The Lady Vera Moyle had made herself notorious in a cause that scored some points through her allegiance. She it was who cajoled the Home Secretary outside Palace Yard, and sent him about his weighty business with the colors of a hated Union pinned to his unconscious back. It is true that some of her excesses had less to redeem them, but all were committed with a pious zest which recalled the saying that the Moyles were a race of Irish rebels who had intermarried with the saints. It was reserved for Lady Vera to combine the truculence of her forefathers with the serene solemnity of their wives, and to enact her devilments, as she took their consequences, with a buxom austerity all her own.

But she was not at her best when she went to see Doctor Dollar on Christmas Eve; for it was just two months after the autumn raid, which had caused the retirement of Lady Vera Moyle, and some of her political friends, for precisely that period. Otherwise, the autumn raid had been a triumph for the raiders, thanks to a fog of providential density, which had fought on their side as the stars in their courses fought against Sisera for the earliest militant. Never had private property been destroyed on so generous a scale, with fewer casualties on the side of the destroying angels; and yet there had been one unnecessary blot on the proceedings, which they were the first to repudiate and condemn.

A vile male member of the common criminal classes had not only taken occasion to loot a jeweler's window, broken by some innocent lady, but had coolly murdered a policeman who interfered with him in the perpetration of his selfish crime. Fortunately the wretch had been traced through the stolen trinkets, expeditiously committed and condemned, and was on the point of paying the supreme penalty. No sane person could doubt his guilt, and yet there were those who sought to fix a certain responsibility on the women! The charge of moral complicity had disgraced and stultified both Press and platform, and the Home Secretary, pestered for a reprieve, had only sealed the murderer's fate at the eleventh hour. Even the steel nerves of the Vinsons had suffered under a complex strain: it was just as well that he was on the point of departure for the holidays.

A deplorable circumstance was the way the Minister's last hours in town had been embittered by his implacable tormentor, Lady Vera Moyle. That ingrate had celebrated her release by trying to invade the Home Office, and by actually waylaying the Secretary of State in Whitehall. An unobtrusive body-guard had nipped the annoyance in the bud; but it had caused Topham Vinson to require champagne at his club, whither he was proceeding on the arm of his last ally and most secret adviser, Doctor John Dollar of Welbeck Street. And before dark the doctor had been invaded in his turn.

"You must blame the Home Secretary for this intrusion," began Lady Vera, with all the precision of a practised speaker who knew what she had to say. "He refused, as you heard, to listen to what I had to say to him this morning; but the detective-in-waiting informed me that you were not only a friend of Mr. Vinson's, but yourself a medical expert in criminology. I have therefore a double reason for coming to you, Doctor Dollar, though it would not have been necessary if Mr. Topham Vinson had treated me with ordinary courtesy."

"I am very glad you have done so, Lady Vera," rejoined the doctor in his most conciliatory manner. "Mr. Vinson, to be frank with you, is not in a fit state for the kind of scene he was afraid you were going to make. He is in a highly nervous condition for a man of his robust temperament. Truth, Lady Vera, compels me to add that you and your friends have had something to do with this, but the immediate cause is a far more unhappy case which he has just settled."

"Has he settled it?" cried Lady Vera, turning paler than before between her winter sables and a less seasonable hat.

"This morning," said Dollar, with a very solemn air.

"He isn't going to hang that poor man?"

No breath came between the opened lips that prison had bleached and parched, but neither did they tremble as the doctor bowed.

"If you mean Alfred Croucher," said he, "convicted of the murder of Sergeant Simpkins during the last suffragist disturbance, I can only say there would be an end of capital punishment if he had been reprieved."

"Doctor Dollar," returned Lady Vera, under great control, "it was about this case, and nothing else, that I wanted to speak to the Home Secretary. I never heard of it until this morning, for I have been out of the way of newspapers, as you may know; and it is difficult to take in a whole trial at one hurried reading. Do you mind telling me why everybody is so sure that this man is the murderer? Did anybody see him do it?"

The crime doctor smiled as he shook his head.

"Very few murders are actually witnessed, Lady Vera; yet this would have been one of the few, but for the fog. Croucher was plainly seen through the jeweler's window, helping himself one moment, then struggling with the unfortunate sergeant."

"Was the struggle seen as plainly as the robbery?"

"Not quite, perhaps, but the evidence was equally convincing about both. Then the stolen goods were found, some of them, still in Croucher's possession; and the way he tried to account for that, in the witness-box, was only less suicidal than his fatal attempt at an alibi."

"Poor fool!" exclaimed Lady Vera, with perhaps less pity than impatience. "Of course he was there—I saw him!"

Dollar was not altogether unprepared for this.

"You were there yourself, then, Lady Vera?"

"I should think I was!"

"It—it wasn't you who broke the window for him?"

"Of course it was! Yet nobody tried to find me as a witness! It is only by pure chance that I come out in time to save an innocent man's life, for innocent he is of everything but theft. I know—too well!"

Her voice was no longer under inhuman control; and there was something in its passionate pitch that sent a cold thrill of conviction down Dollar's spine. He gazed in horror at the unhappy girl, in her luxurious sables, drawn up to her last inch in the pitiless glare of his electric light; and even as he gazed—and guessed—all horror melted into the most profound emotion he had ever felt. It was she who first found her voice, and now it was calmer than it had been as yet.

"One thing more about the trial," she said. "What was the weapon he is supposed to have used?"

"His knife."

"Yet it seems to have been a small wound?"

"It had a small blade."

"But was there any blood on it?"

She had to press him for these details; any squeamishness was on his side, and he a doctor!

"There was," he said. "Croucher had an explanation, but it wasn't convincing."

"The truth often isn't," said Lady Vera, bitterly. "You may be surprised to hear that the blow wasn't struck with a knife at all. It was struck with—this!"

Her right hand flew from her glossy muff; in it was no flashing steel, but a short, black, round-knobbed life-preserver, that she handed over without more words.

"But his skull wasn't smashed!" exclaimed John Dollar, and for an instant he looked at his visitor with the eye of the alienist. "It was a puncture of the carotid artery, and you couldn't do that with this if you tried."

"Hit the floor with it," said Lady Vera, "but don't hold it quite by the end."

Dollar bent down and did as directed; at the blow, a poniard flew out of the opposite end to the round knob; the point caught in his sleeve.

"That's how it was done," continued Lady Vera. "And I am the person it was done by, Doctor Dollar!"

"It was—an accident?" he said, hoarsely. He could look at her as though the accident had not been fatal; he had less command of his voice.

"I call it one; the law may not," said she resignedly. "Yet I didn't even know that I possessed such a weapon as this; it was sold to me as a life-preserver, and nothing else, out of a pawnbroker's window, where I happened to see it on the very morning of the raid. I thought it would be just the thing for smashing other windows, especially with that thong to go round one's wrist. I thought, too—I don't mind telling you—that, if I were roughly handled, it was a thing I could use in self-defense as I couldn't very well use a hammer."

And here she showed no more shame than a soldier need feel about his bayonet after battle; and Dollar met her eyes on better terms. He had been making mechanical experiments with the life-preserver. Some spring was broken. That was why it became a dagger at every blow, instead of only when you gave it a jerk.

"And you were roughly handled by Sergeant Simpkins?" he suggested eagerly.

"Very," she said, with a certain reluctance. "But I expect the poor fellow was as excited as I was when I tried to beat him off."

"I suppose you hardly knew what you were doing, Lady Vera?"

"Not only that, Doctor Dollar, but I didn't know what I had done."

"Thank God for that!"

"But did you imagine it for a moment? That's the whole point and explanation of everything that has happened. The worst was over in a few seconds, in the thick of that awful fog, but, of course I never dreamt what I had done. I did think that I had knocked him out. But that was all that ever entered my head until this very morning."

"Were you close to your broken window at the time?"

"Very close, and yet out of sight in the fog."

"And you had seen nothing of this man Croucher, and his hand in the affair?"

"Not after I'd done my part. I did just before. I'm certain it was the same huge man that they describe. But I heard the whole thing while we were struggling. They were blowing a police-whistle and calling out 'Thieves!' I remember hoping that the policeman would hear them, and let me go. But I suppose his blood was up, as well as mine."

"And after you had—freed yourself?" said the doctor, trying not to set his teeth.

"I ran off, of course! I knew that I had done much more than I ever intended; but that's all I knew, or suspected, even when I found this horrid thing open in my hand. I tried to shut it again, but couldn't. So I hid it in my dress, and ran up Dover Street to my club, where I put it straight into a bag that I had there. Then I made myself decent and—turned out again with a proper hammer."

The doctor groaned; he could not help it. Yet it was his first audible expression of disapproval; he had restrained himself while all the worst was being told; and the girl's face acknowledged his consideration. Her color had come at last. Thus far, in recounting her intentional misdeeds, as though they were all in the great day's work, she had shown a divine indifference to his opinion of her or her proceedings. There had been nothing aggressive about it—he merely doubted whether the question of his views had ever entered her mind. But now he could see that it did; he had shown her something that she did not want to lose, and her fine candor hid that fact as little as any other.

"I didn't know what I'd done, remember!" she said with sharp solicitude. "I never did know until this morning, when I heard of the case for the first time, and for the first time saw the stains on the dagger—at which you've been trying so hard not to look! Do look at them, Doctor Dollar. Of course, there can be no doubt what they are, but I shall be only too glad for you to prove it to everybody's satisfaction."

"'Only too glad,' Lady Vera?"

They gazed at each other for several seconds. Her face was tragic to him now; but emotion, apparently, was the one thing she would condescend to hide. But for her eyes, she might have been incredibly callous and cold-blooded; her blue Irish eyes were great and glassy with a grief not soluble in tears.

"Doctor Dollar," she said, tensely, "nothing can undo this hideous thing, though I hope to live long enough to make such poor amends as a human being can. But in this other direction they must be made at once. It's no use thinking of what can't be undone till we have undone what we can—if we are quick! That's why I tried to go straight to the Home Secretary, and why I have come straight to you. Take me to him, Doctor Dollar, and help me to convince him that what I have told you is the whole truth and nothing else! If you think it will make it easier, satisfy yourself about those blood-stains. Then we can take the dagger with us."

The doctor applied a crude test on the spot. He stooped over the fire, heated the stained steel between the bars, cooled it at the open window, picked off a scale and examined it briefly under a microscope. All this was done with tremendous energy tempered by extreme precision and nicety. And Lady Vera followed the operation with an impersonal interest that could not but include the operator, so intent upon his task, so obviously thankful to have a task of any sort in hand. But when he rose from his microscope it was with a shrug of the shoulders, an almost angry shake of the head.

"Of course, this is all no good, you know!" he cried, as if it were her test. "It would take hours to make the analysis that's really wanted."

"But as far as you have gone, Doctor Dollar?"

"As far as I have gone—which isn't a legal or medical inch—it certainly does look like blood, Lady Vera."

"Of course it is blood. There's another thing that will help us, too."

"What's that?"

"One of the best points in the defense, so far as I've had time to make out, was about the prisoner's knife. Now, if we take this with us, either to the Home Secretary, or, if he still refuses to see me, to New Scotland Yard——"

"Lady Vera!" the doctor interrupted, aghast at her suicidal zeal. "Is it possible that you realize the position you are in? It isn't only a situation that you've got to face; that you have already done, superbly! But have you any conception of the consequences?"

"I think I have," said Lady Vera, smiling. "I don't believe they will hang me; it would be affectation to pretend I did. But, of course, that's their business—mine is to change places with an innocent man."

"That you will never do," replied the doctor warmly. "There's no innocent man in the case; this Croucher is a thief and a perjurer, besides being an old convict who has spent half his life in prison! He would have had five years for the other night's work, without any question of a murder; they'll simply pack him off to Dartmoor or Portland when we've saved his miserable neck. And save it we will, no fear about that; but at what a price—at what a price!"

"I don't see that you need trouble about it," said Lady Vera, concerned at his distress, "beyond putting me in touch with Mr. Vinson. The rest will be up to him, as they say; and, after all, it won't be anything so very terrible to me. I am an old prisoner myself, you must remember!"

There was a gleam of her notorious audacity with all this; but it was like the glow of flowers on a grave. The horror of things to happen had never possessed her valiant eyes, and yet it must have been there, for all at once Dollar missed it. He read her look. He had relieved her mind about the man in the cell, only to open it at last to the man in his grave. Grief crippled her as horror had not; prisons could be broken, but not the prison to which her hand had sent a fellow creature. Yet her grief was mastered in its turn, forced out of sight before his eyes, even while her flippant speech rang through him as the bravest utterance he had ever heard.

It blew a bugle in the man's brain, and the call was clear and definite. He knew his own mind only less instantaneously than he had penetrated hers. Never in all his days had he known his mind quite so well as when she thought better of the very words which had enlightened him, and went on to add to them in another key:

"So now, Doctor Dollar, will you crown all your great kindness by taking me to see the Home Secretary at once?"

"Lady Vera," he exclaimed, with unreasonable irritation, "what is the good of asking impossibilities? I couldn't take you to Topham Vinson even if I would. He would begin by doubting your sanity; there would be all manner of silly difficulties. Moreover, he's not in town."

She showed displeasure at the statement of fact only.

"Doctor Dollar, are you serious?"

"Perfectly."

"Have you forgot that I saw you together at almost two o'clock?"

"I think not quite so late as that. The Home Secretary left Euston at 2:45."

"Where for?"

She looked panic-stricken.

"I'll tell you, Lady Vera, if you promise not to follow him by the next train."

"When does it go?"

"Not for some time. There's only one more; we debated which he should take. But you mustn't take the other, Lady Vera; you must leave that to me. I want you to leave the whole thing to me—from this very moment till you hear from me again."

"When would that be, Doctor Dollar?"

"As soon as I have seen Mr. Vinson."

"You would undertake to tell him everything?"

"Every detail, exactly as you have told me."

"Will it seem credible at second-hand?"

"Quite enough so to justify a respite. That's the first object; and this is the first step to it, believe me! There's plenty of time between this and—Tuesday."

"Oh! I know that," she returned, bluntly disdainful of a well-meant hesitation. "There's still not a moment to lose while that poor man lies facing death."

"I'm not sure that he does, Lady Vera. The decision's only just been made; it won't be out till the day after to-morrow. I don't believe they would break it to Croucher on Christmas Day."

"They can break the good news instead. Where is Mr. Vinson? It's all right, I won't attempt to tackle him till you have. That's a promise—and I don't break them like windows!"

John Dollar ignored that boast with difficulty. He saw through her tragic levity as through a glass, and his heart cried out with a sympathy hard indeed to keep to himself; but it was obviously the last thing required of him by Lady Vera Moyle. He gave her the required information in a voice only less well managed than her own. And he thought her eyes softened with the faintest recognition of his restraint.

"I thought the Duke had washed his hands of his notorious nephew," she remarked. "Well, we shall have to spoil the family gathering, I'm afraid."

"That's my job, Lady Vera."

"And I never thanked you for taking it on! Nor will I, Doctor Dollar; thanks don't meet a case like this!" Very frankly she took his hand instead: it was hotter and less steady than her own. "And now what about your train?"

"I'm afraid there's not one till seven o'clock. Vinson talked of going down by it at first."

The time-table confirmed his fear; he threw it down, and plunged into the telephone directory instead. Lady Vera watched him narrowly. He had dropped into his old oak chair, and the sheen of age on the table betrayed his face as though it were bent over clear brown water. She could see its anxiety as he had not allowed her to see it yet.

"I suppose you wouldn't care to face it in a motor?"

She was faltering for the first time.

"That's exactly what I mean to do," he answered, without looking up from the directory. "I'm just going to telephone for a car."

"Then you needn't!" she cried joyfully. "We have at least two eating their bonnets off in our mews. I'll go home in a taxi, and send one of them straight round with a driver who knows the way, and a coat that you must promise to wear, Doctor Dollar. All my people are away except my mother, and she won't know; she isn't strong enough to use the cars. But I mustn't speak of poor mother, or I shall make a fool of myself yet. It's partly my fault as it is, you see, and of course all this will make her worse. But I'm not so sure of that, either! My mother is the kind of person who has all the modern ailments and no modern ideas—but she could show us all how to play the game at a pinch. She will be the first to back me up in the only conceivable course."

This speech had not come quite so fluently as might be supposed, though Dollar had only interrupted it to send for a taxicab. It had interrupted itself when Lady Vera Moyle was betrayed into speaking of poor Lady Armagh, whose heart-felt disapproval of her daughter's escapades was public property. Dollar had heard from Topham Vinson—that very day at lunch—that the last one had made her seriously ill; then what indeed of impending resolutions, and the nine days' tragic scandal which was the very least that could come of them unless——

"Unless!"

In the doctor's mind so many broken sentences began with that will-o'-the-wisp among words, that others really spoken fell upon stony ears, and he knew as little what he said in reply. In a dream he saw a small hand wave as the taxicab vanished round the corner to the right; in a dream he sprang up-stairs, hiding under his coat the weapon with which that little hand had dealt out death; and awoke in his wintriest clothes, his greatest coat, to find himself called upon to top the lot with another of unkempt fur sent with the car.

That aluminum clipper—a fifteen-horse-power Invincible Talboys—was indeed at the door in incredibly quick time. Twin headlights lit long wedges of London mud; two pairs of goblin goggles mounted up behind them—one sent with the coat and a message that was more than law. The dapper chauffeur huddled down behind the wheel; the passenger sat bolt upright at his side; the Barton family, his faithful creatures, carried out an impromptu tableau in the background. Mother and son—those unpresentable features of a former occasion—now appeared as immaculate cook and page at the top of the area steps and on the lighted threshold respectively. Barton himself leaned out of an upper window, still in his white suit—it was the typically muggy Christmas of a degenerate young century—but with all the black cares of the strange establishment quite apparent on his snowy shoulders. The dapper driver gave his horn a spiteful pinch. And then they were off, only to be held up in Oxford Street by the Christmas traffic, but doing better in the Edgware Road, and soon on the way to Edgware itself, and Elstree and St. Albans, and all the lighted towns and pitch-dark roads that lie by night between the capital of England and her smallest county.

"Least trem-lines this wye," said the dapper one, a mile or two out; and said no more for another fifty. But he drove like a little genius, and the car responded to his cunning hands as a horse that knows its master. She proved to be a sound roadster whose only drawback was a lack of racing speed; the lad had her in prime condition, and the good road ran from under her like silk from a silent loom.

Dollar sat beside him, in the shelter of a wind-screen that glazed and framed a continuous study in nocturnal values. Now the fine shades would be broken by a cluster of lights, soon to scatter and go out like sparks from a pipe; now only by the acetylene lamps that kept the foreground in a blaze between villages. Often a ghostly portent appeared hovering over the road ahead; but this was only the doctor's own anxious face, seen dimly in the screen.

And yet he was not really anxious for those first fifty miles. At the start he was too thankful to be under way, and the road was never empty of exciting and diverting possibilities. But at Bedford they stopped for supper: it was Dollar's sudden idea, the hour being now between eight and nine; but the treasure at the wheel professed his readiness to push on, and it would have been better for Dollar to have taken him at his word. The break in the run also broke up the dreamy lull induced by the keen air and the low smooth hum of the car. In the warm hotel, all holly and Christmas cheer, he came back to real life with a thud, and its most immediate problem beset him all the rest of the way.

Hitherto his one anxiety had been to get at the Home Secretary that night; henceforth he was having the interview over and over again, with a different result every time. He knew, indeed, what he meant to say himself; he had known that before he said good-by to Lady Vera Moyle. But what would the Home Secretary say? Was it conceivable that the blood-stained life-preserver would be enough for him? It would be supported by the sworn statement of a man whom he had learned to trust. But was such utterly indirect evidence in the least likely to upset a decision already taken, if not already communicated to the man in the condemned cell?

The very thought of that hapless wretch was fraught with definite and vivid horror. The crime doctor had once seen the inside of a condemned cell; he could see it still. The door was open, the pitiful occupant at exercise in an adjacent yard. He had looked in. The cell was not so gloomy as it should have been. Texts on the walls, sunlight through the bars, and on the fixed flap of clean worn wood, a big open book.

Dollar recalled every detail with morbid fidelity. He had gone in to look at the book, and found it a bound volume of Good Words, open at a laudable serial by a lady then in vogue with the virtuous. Yet that particular reader had cut a woman's throat over a quarrel about a shilling, and Dollar had seen him striding jauntily up and down the narrow yard, cracking some joke with the attendant warders, a smile on his scrubby lips and in his bold blue eyes. He could see the fellow as he had seen him for ten seconds years ago. Yet his pity for one in the same awful case, for a crime he had not committed, was as nothing to his infinite sorrow and compassion for her who had committed it unawares, comparatively light as the punishment for such a deed was bound to be.

But was it? Not for Lady Vera Moyle, at all events! Either she would go scot-free, or her punishment might well be worse than death. It might easily kill her mother; then the tragedy would be a double tragedy after all, and Lady Vera would still be its author. Supposing she had not discovered her own crime! Croucher would have been no loss to the community; life-long criminals like Croucher were best out of the way, murderers or no murderers. The crime doctor was convinced of that. They were the incurables; extermination was the only thing for them.

"I would shut up my penitentiaries, but enlarge my lethal chamber," he sometimes said, and would be quite serious about it. Yet not for a moment could he have carried his ideas to their logical conclusion in the concrete case of Alfred Croucher and Lady Vera Moyle. He could have let a man of that stamp go technically innocent to the gallows—or he thought he could just then. But he could not have allowed the greatest monster to suffer for Lady Vera's sins—and that he felt in his bones. It was the personal equation as supplied by her that made the thing impossible. Such a load on such a soul! Better any punishment than that!

At Kettering a right-hand turn led up-hill and down-dale into little Rutland, and Dollar ceased glaring at his own ghost in the wind-screen; a healthily immediate anxiety kept him peering at his watch instead. But now they were skirting one of the longest and stumpiest stone walls in feudal England, and all of a sudden it parted in twin turrets joined by triple gates. Over the central arch heraldic monsters pawed the stars; underneath an arc lamp hung resplendent; all three gates were open, and the drive beyond was a perspective of guiding lights. It was evidently a case of Christmas festivities on a suitable scale at Stockersham Hall.

Miles up the drive, a semicircle of motor-cars fringed a country edition of the Horseguards Parade, dominated by an escaped hotel; and the car that really was from London had becoming palpitations in the zone of light. Before a comparatively simple portico a superlatively splendid menial looked askance at the doctor's borrowed furs, but was not unimpressed by a curt inquiry for Mr. Topham Vinson, and consented to inquire in his turn.

"Be quick and quiet, and give him this card," said the doctor, slipping half-a-sovereign underneath it. "I want to see Mr. Vinson—no one else—on urgent business from the Home Office."

Yet the next minute merely brought forth an imposing personage whom the dapper driver did not fail to salute; even Dollar was not positive whether it was the Duke or his butler until summoned indoors with the subtle condescension of the supreme servitor. He went as he was, in hirsute coat and goggles, the butler stalking at arm's length, with an air of personal repudiation happily not lost upon the little London lynx in charge of the car.

That artist would have been an endless joy to eyes not turned within. His silent endurance and efficiency, his phlegmatic zest in an adventure which might have a professional interest for him, but obviously did not engage his curiosity, were qualities which even the tormented Dollar had appreciated at intervals on the road. But now he missed a treat. The little Cockney ran his engine till the first flunkey returned and said things through the noise. Then he looked under his bonnet, as a monkey into its offspring's head. But the climax arrived with sandwiches on a lordly tray, when a glass of beer was sent back, and one of champagne brought instead to this choice specimen of a contemporary type. It was scarcely down before the passenger reappeared, accompanied by another swollen figure in motoring disguise, as well as by my Lord Duke, who saw them off himself, and did look less ducal than the butler after all.

The many lights of Stockersham dwindled and disappeared into the night and one long wave of incandescence flowed back as it had come, by finespun hedge and wirework thicket, through dead villages and sleeping towns, like phosphorescent foam before a vessel's bows. And in the torpedo body of the Invincible Talboys, where Dollar now sat behind his companion of the outward trip, and the Home Secretary of England behind a fat cigar, there was a strained silence through two entire counties, but something like an explosion on the confines of the third.

"Do you still refuse to give her name?" demanded Topham Vinson, exactly as though they had been talking all the time. The stump of his second cigar was so short that angry light and angry mouth were one.

"I must," said Dollar, in a muffled voice, and he pointed to the hunched shoulders within a yard of their noses.

"In that case we have no secrets," replied the Home Secretary with a sneer. "But why must you, Dollar? She seems to have made no reservations with you, yet you would make this enormous one with me."

"It's a secret of the consulting-room, Mr. Vinson; those of the confessional are not more sacred, as you know perfectly well."

"And you expect me to eat my decision on the strength of a hearsay anonymous confession?"

"I do—in the first instance," said Dollar decidedly. "An immediate respite would commit you to nothing, but I don't ask even for that on the unsupported strength of what I told you at Stockersham. You know what you've got in your overcoat pocket. Hand it over to your own analyst; have an exhumation, if you like, and see if the weapon doesn't actually fit the wound; if it doesn't, hang your man."

"I'm much obliged for your valuable advice. But it's got to be one thing or the other, once for all; the poor devil has been on tenter-hooks quite long enough."

"And have you forgotten how nearly you decided in his favor, Mr. Vinson, without all this to turn the scale?"

It was perhaps an ominous feature of their mushroom intimacy that the younger man had not yet been invited to drop the formal prefix in addressing his senior by a short decade. But this would not have been the moment even for a familiarity encouraged in happier circumstances. And yet Dollar dared to pat the great man's arm as he spoke; and the gesture was as the button on the foil; it prevented a shrewd thrust from drawing blood, and if anything it improved Topham Vinson's temper.

"It's no good, my dear fellow!" he exclaimed in friendly settlement of the general question. "I must have the lady's name, unless she's determined to defeat her own ends."

"Do you mean to say that it's her name or Croucher's life?"

Topham Vinson had not meant to say any such thing—in so many words—and it was annoying to have them put into his mouth. But he had decided not to be annoyed any more. It did not pay with this fellow Dollar; at least, it had not paid on that occasion; but anybody might be at a disadvantage after a heavy political strain, a lengthy journey, an excellent dinner, and a development as untimely as it was embarrassing. Mr. Vinson relapsed into silence and an attitude unconsciously modeled on that of the gallant little driver. His body sank deep into the rugs, his head as deep between his shoulders. It was almost Hertfordshire before he spoke again.

"Vera Moyle was one of the Oxford Street division," he remarked at last. "I know all about her movements on the night of battle; otherwise I should want to know about them now. If I thought she was the woman——"

"What's that?" said Dollar lethargically. "I was almost asleep."

The remarks did not gain weight by repetition, but the broken sentence was finished with some effect: "I'd let her drain the cup."

"I don't wonder," rejoined Dollar, sympathetically.

"Yet you would have me risk my political existence for one of her kidney!"

"I don't follow."

"You would reprieve the apparent murderer, and let the real one continue militant here on earth?"

"I believe she has had her fill of militancy."

"Not she!"

"I'll go bail for her if you like. It was an accident She is heart-broken about it—and you don't know her—I do! I'd back her not to run the risk of such another accident!"

"And what if she rounded on me? However such a thing came out, it would be my ruin, Dollar."

"It wouldn't come out through her!"

A certain fervor crept into the doctor's voice. It was obviously unconscious, and Topham Vinson was far too astute a person to engender consciousness and caution by so much as a rallying syllable. But he did hazard a leading question, subtly introduced as nothing of the sort.

"I'm not trying to get at what I want in a roundabout way," he had the nerve to state. "I've given up trying to pump you, Dollar; but—would it make a very great scandal if we had to fix this thing on this particular young lady?"

"I can't answer about scandals," replied the still not unwary doctor. "It would break hearts—probably cause death—make her a double murderer in her own eyes, and God knows what else as a result! And it wouldn't do anybody the least bit of good, because you would still have to give Croucher a suitable term for his authentic offense."

It was three o'clock on Christmas morning when they saw the lights of London from the top of Brockley Hill; a minute later they were on the tram-lines at the foot, and almost immediately in the purlieus of the town.

The trip did not end without a telling taste of Mr. Vinson's very individual quality. In Maida Vale he suddenly announced his intention of having the life-preserver identified in those very small hours by the pawnbroker who had sold it on the morning of the autumn raid. The crime doctor was terrified; for aught he knew the man might be well aware that he had sold it to Lady Vera Moyle. She was notorious enough, in all conscience; his only hope lay in the fact that he himself had not known her by sight before that day. In vain he raised various objections; they were well met by his own previous arguments for the immediate reprieve of Alfred Croucher, and he feared to press them. He knew only the name of the pawnbroker's street, but here Cockney sharpness came in again, and they were pounding on the right shutters by half past three. An up-stairs window flew alight, up went a sash, and out came an angry head.

"My name is Topham Vinson," said one of the swaddled men in a sepulchral voice. "I'm the Home Secretary, but I can't force you to come down and speak to me because of that. I can only make it more or less worth your while."

He was fishing for his sovereign-case as he spoke. In another minute the private door had shut behind him and Doctor Dollar, and an obsequious sack of humanity shuffled before them into a sanctum still redolent of a somewhat highly-seasoned meal.

"I remember 'aving it in the thop," said the unkempt head protruding from the sack. "But I can't thay 'ow it came here—that I can thwear in a court of juthtith, my lord! It'th a narthy, beathly thing, but I thwear it wath here when I took over the bithneth."

"I don't care how or when it came here," said Topham Vinson, counting the sovereigns in the gold case attached to the watch-chain of other memories. "I want to know if you remember selling this life-preserver?"

"Yeth, I do!"

"When?"

"It would be—let me thee—thome time lartht October or November."

"Do you remember who bought it?"

"Yeth—a young lady!"

Dollar breathed again. The man did not know her name; at first he was extremely shaky on the point of personal appearance. But the doctor assisted him by unscrupulously suggesting a number of marked characteristics which Lady Vera Moyle did not happen to possess. The man fell straight into the trap, recalled every imaginary feature, and finally earned big gold by quite convincingly connecting the sale of the life-preserver with the date of the great women's raid. Mr. Vinson looked very stern as he led the way out into the street; and it was he who sharply woke the little chauffeur, who was snoring heartily over his wheel.

"I like that lad," he muttered in the car. "He does nothing by halves. No more do I! Do you mind dropping me first at Portman Square?"

Dollar gave the order, and they slid through the empty streets as though man and car were fresh from the garage. There was not a soul in Portman Square, or a light in any of the houses except the Home Secretary's. They had telephoned through from Stockersham after his departure, and the door opened as he emptied his remaining sovereigns into the chauffeur's hand, before taking Dollar's with no lack of warmth.

"I can't ask you in this time," said Topham Vinson, smiling. "Apart from the hour, I've got to go straight to the telephone, get through to Pentonville, and spoil the Governor's night!"

"Reprieved?" gasped the doctor. It was the one word that would come.

The Home Secretary nodded rather grimly, but was smiling as he shut the door almost on the hand with which John Dollar would have seized his once more. There was a shooting of bolts inside.

Dollar turned slowly round, wondering if at last he could tell the little driver something about the night's enterprise in which he had played so heroic a part. There was no need. The driver had kept eyes and ears wide open—and collapsed once more over the wheel. This time it was not in sleep, but in a dead faint; and the driving goggles were all awry, the driver's hat had tumbled off, the driver's hair had broken bounds.

It was a girl's hair, and the girl was Lady Vera Moyle.
