The card of Major Bingham Wrynche, C.B., was brought to Saxham one morning, as, his early-calling patients seen and dismissed, the Doctor was going out to his waiting motor-brougham.

Bingo, following what he was prone to call his pasteboard, presented himself—a large, cool, well-bred, if rather stupid-looking, man, arrayed in excellently-fitting clothes, saying:

"You were goin' out? Don't let me keep you. Look in again!"—even as he deposited a tightly-rolled silk umbrella in the waste-paper basket, and tenderly balanced his gleaming hat upon the edge of the writing-table, and chose, by the ordeal of punch, a comfortable chair, as a man prepared to remain. Saxham, pushing a cigar-box across the consulting-room table, asked after Lady Hannah.

"First-rate! Seems to agree with her, having a one-armed husband to fuss over!"

"She won't have a one-armed husband long," returned Saxham, not unkindly, glancing at the bandaged and strapped-up limb that had been shattered by an expanding bullet, and was neatly suspended in its cut sleeve in the shiny black sling.

"By the Living Tinker! she's had him long enough for me!" exploded Bingo, who seemed larger and fussier than ever, if a thought less pink. "So'd you say if they tucked a napkin under your chin at meals, and cut your meat up into dice for you, and you'd ever tried to fold up your newspaper with one hand, or had to stop a perfect stranger in the street, as I did just now outside your door, and ask him to fish a cab-fare out of your right-hand trouser-pocket if he'd be so good? because your idiot of a man ought to have put your money in the other one."

"You're lookin' at my head," pursued the Major, "and I don't wonder. She's been and given me a fringe again. 'Stonishing thing the Feminine Touch is. Let your servant part your hair and knot your necktie, and you simply look a filthy bounder. Your wife does it—and you hardly know yourself in the glass, and wonder why they didn't christen you Anna-Maria. Not bad weeds these, by half! You remember those cigars of Kreil's and the thunderin' price me and Beauvayse paid for 'em, biddin' against each other for fun?" The big man blew a heavy sigh with the light blue smoke-wreath, and added: "And before the last box was dust and ashes, poor old Toby was! And that chap Levestre—never fit to brown his shoes—is wearing 'em; and 'll be Marquess of Foltlebarre when the old man goes. Queer thing, Luck is—when you come to think of it?"

Saxham nodded and looked at the clock. A dull impatience of this large, bland, prosperous personage was growing in him. From the rim the top-hat had left upon his shining forehead to the tightly-screwed eyeglass that assisted his left eye; from the pink Malmaison carnation in the buttonhole of his frock-coat to the buff spats that matched his expansive waistcoat in shade, the large Major was the personification of luxurious, pampered, West End swelldom, the type of a class Saxham abhorred. He had seen the heavy dandy under other conditions, in circumstances strenuous, severe, even tragic. Then he had borne himself after a simple, manly fashion. Now he had backslidden, retrograded, relaxed. Saxham, always destitute of the saving sense of humour, frowned as he looked upon the pampered son of Clubland, and the sullen lowering of the Doctor's heavy smudge of black eyebrow suggested to the Major that his regrets for "poor old Toby!" had been misplaced. The man who had married Miss Mildare could hardly be expected to join with heartiness in deploring the untimely decease of his predecessor.

"Not that it could have come to anything between poor Toby and her if the dear old chap had lived," reflected Bingo, and wondered if the Doctor knew about—about Lessie? "Bound to," he mentally decided, "if he keeps his ears only half as open as other men keep theirs. Didn't a brace of bounders of the worst discuss the story in all its bearin's, sittin' behind my wife and Mrs. Saxham in the stalls at the theatre the other night! Everybody is discussin' it now that the Foltlebarres have left off payin' Lessie not to talk, and provided for her and the youngster out of the estate, and Whittinger's given her a back seat in the family.... That family, too!... Lord! what a rum thing Luck is!"

The musing Major cleared his throat, and his large, rather stupid, blonde face was perfectly stolid as he smoked and stared at his host, reminding himself that Beauvayse had been jealous of Saxham, Attached Medical Staff, Gueldersdorp, and had feared that, if the fellow knew of the scratch against him, he might force the running; and recalling, with a tingling of the shamed blood in his expansive countenance, how he—Wrynche—had let Beauvayse into the sordid secret that Alderman Brooker had blabbed. He wondered, looking at the square, set face, whether Saxham had ever really earned the degrading nickname that he could not get quite right. The 'Peg Doctor,' was it?—or the 'Lush Doctor?' Something in that way.... Not that Saxham looked like a man given to lifting his elbow with undue frequency....

"—But you never know," thought experienced Bingo sagely, even as, in his heavy fashion, he went pounding on: "The Chief's continuin' the Work of Pacification, and acceptin' the surrender of arms—any date of manufacture you like between the chassepot of 1870 and the leather-breeched firelock of Oliver Cromwell's time. The modern kind, you find by employin' the Divinin' Rod"—the large narrator bestowed a wink on Saxham and added—"on the backs of the fellows who buried the guns. Never fails—used in that way. And—as it chances—I have a communication to make to you."

"A communication—a message—from the Chief to me?"

Saxham's face changed, and softened, and brightened curiously and pleasantly.

Major Bingo nodded and cleared his throat. He rebalanced his shiny hat upon the table corner, and said with his eyes engaged in this way:

"I was to remind you—from him—that—not long before the ending of the Siege, a lady who is now a near connection of yours sustained a terrible bereavement through the—infernally dastardly crime of a—person then unknown!"

Saxham's vivid eyes leaped at the speaker's as if to drag out the knowledge he withheld. But Bingo was balancing the glossy triumph of a Bond Street hatter, and looked at it and not at the Doctor, who said:

"You refer to the murder of the Mother-Superior at the Convent of the Holy Way on February the —th, 1900. And you say a person then unknown.... Has the murderer been arrested?"

Major Bingo shook his head.

"He hasn't been arrested, but his name is known. You remember the runner who came in from Diamond Town with a letter for a man called Casey? Not long after—after my wife was exchanged for a spy of Brounckers'?"

"I did not see the man myself," returned Saxham, "but I perfectly recollect his getting through."

Major Bingo said:

"I thought you would. Well, the letter was a blind; the bearer an agent of the firm of Huysmans and Eybel, sent to make certain of our weakest points before they put in the attack on the Barala town; and—that's the man who committed the murder!"

"The man who committed the murder?"

Saxham's vivid eyes were intent upon the Major's face. The Major coughed, and went on:

"My wife came across that man at Tweipans under curious circumstances, which I'm here to put before you as plainly as may be.... She'd met him before the Siege, travelling up from Cape Town. He scraped acquaintance, called himself a loyal Johannesburger, and an Agent of the British South African War-Intelligence-Bureau. Not that there ever was such a Bureau." Major Bingo blinked nervously, and ran a thick finger round the inside of his collar as he added: "The beggar spoofed Lady Hannah up hill and down dale with that, and she believed him. And when she subsequently flew the coop—dash this cold of mine!..."

The Major drew out a very large pink cambric pocket-handkerchief, and performed behind its shelter an elaborate but unconvincing sneeze:

"—When she shot the moon with Nixey's mare and spider, it was by private arrangement with this oily, lying blackguard, who had given her an address—a farm on the Transvaal Border, known as Haargrond Plaats—where she might communicate with him through another scoundrel in the Transport Agency line, supposin' she chose to do a little business on her own in Secret Intelligence——"

Saxham interrupted:

"I shall say nothing to my wife of this, and I trust you will impress upon Lady Hannah that it would be highly inadvisable for her to do so."

"She won't, you may depend on it." Major Bingo palpably grew warm, and mopped the dew from his large, kind, rather stupid countenance with the pink cambric handkerchief—"She's awfully afraid, as it is, that a word or two she dropped quite innocently, to that infernal liar and swindler, who'd bled her of a monkey, good English cash—paid for procurin' and forwardin' items of information that he took damned good care should reach us at Gueldersdorp too late to be of use, led up to—to the crime!... By the Living Tinker! it's out at last!"

The big man, so cool and nonchalant a minute or so before, fanned himself with the pocket-handkerchief, and turned red, and went white, and went red, and turned white half a dozen times, in twice as many beats of his flurried pulse.

"—Out at last, Saxham, and that's why I've been gulpin' and blunderin' and bogglin' for the last ten minutes. Poof!" Major Bingo exhaled a vast breath of relief. "Tellin' tales on a woman—and her your wife—even when she's begged you to, isn't the sweetest job a man can tackle!"

"Let me have this story in detail once and for all," said Saxham, turning a stern, white face, and hard, compelling eyes upon the embarrassed Major. "What utterance of Lady Hannah's do you suppose to have led to the tragedy in the Convent Chapel? Upon this point I must and shall be clear before you leave me!"

"You shall have things as clearly as I can put 'em. This pretended Secret Agent of the War-Intelligence-Bureau that never existed, and who called himself Van Busch—a name that's as common among Boers as Murphy is among Irishmen—arranged to pass off my wife as his sister, a refugee from Gueldersdorp, who'd married a German drummer, and buried him not long before. Women are so dashed fond of play-actin'! Kids, Saxham,—that's what they are in their weakness for dressin' up and makin'-believe! And my wife——"

The large Major was in a violent lather as he ran the thick finger round inside his collar, and swallowed at the lump in his throat.

"—My wife saw Van Busch at Kink's hotel at Tweipans from time to time. He came, I've already explained, to sell bogus information for good money. And as the boodle ran low, the cloven hoof began to show, and the brute became downright insolent."

"As might have been expected," said Saxham, coldly.

"—Kept his hat on in my wife's room, talked big, and twiddled a signet-ring he wore," went on the Major. "And, bein' quick, you know, and sharp as they make 'em, you know, my wife recognised the crest of an old acquaintance cut upon the stone. I knew the man myself"—declared Major Bingo—"and a better never stepped in leather. A brother-officer of the Chiefs, too, and a rippin' good fellow!—Dicky Mildare, of the Grey Hussars."

"Mildare!" repeated Saxham.

"You understand, Saxham, the name did it. My wife had seen the present Mrs. Saxham at Gueldersdorp, and, not knowin' that the surname of Mildare had been taken by her at the wish of her adopted mother, supposed—got the maggot into her head that the Mother-Superior's ward might possibly be a—a daughter of the man the seal-ring had belonged to, knowing—Lord! what a mull I'm making of it!—that Mildare had at one time been engaged to marry that"—the Major boggled horribly—"that uncommonly brave and noble lady, and had, in fact, thrown her over, and made a bolt of it with the wife of his Regimental C.O., Colonel Sir George Hawting."

The faint stain of colour that had showed through Saxham's dead-white skin faded. He waited with strained attention for what was coming.

"South Africa Lady Lucy and Mildare bolted to," went on Bingo, "and now you know the kind of mare's-nest her ladyship had scratched up. And," declared Bingo, "rather than have had to spin this yarn. I'd have faced a Court-Martial of Inquiry respectin' my conduct in the Field. For my wife has a kind heart and a keen sense of honour, and rather than bring harm upon Miss Mildare that was, or anyone connected with her, she'd have stood up to be shot! By G——!" trumpeted Bingo, "I know she would!"

Saxham's face was blue-white now, and looked oddly shrunken. His voice came in a rasping croak from his ashen lips as he said:

"Lady Hannah mentioned my wife to this man, thinking that she might prove to be the daughter of the owner of the ring. What could possibly lead her to infer such a relationship?"

"You must understand that the blackguard had given my wife details of Mildare's death at a farm owned by a friend of his in Natal, and that Hannah—that my wife knew poor little Lucy Hawting had had a child by Mildare," Major Bingo spluttered. "That was why she asked Van Busch outright whether the girl with the nuns at Gueldersdorp was—could be—the same child, grown up? By the Living Tinker!—I never was in such a lather in my life! The better the light I try to put the thing in, the dirtier it looks. And I'm not half through yet, that's the worst of it!"

He mopped and mopped, and took several violent turns about the room, and subsided in a chair at length, and went on, waving the large pink cambric handkerchief, now a damp rag, in the air, at intervals, to dry it.

"She says—Lady Hannah says—that the eagerness and curiosity with which the brute snapped up the hint she'd never meant to drop, warned her to shunt him off on another line, and give no more information. They got on money matters; and, seeing plain how she'd been bilked, my wife gave the welsher a bit of her mind, and he showed his teeth in a way that meant Murder. Just in time—before he could wring her neck round—and he'd started in to do it, you understand—Brounckers came stormin' and bullyin' in, to tell the prisoner she was exchanged, and would be sent down to Gueldersdorp.... They packed her back that very day.... And not a week after, the pretended runner came in from Diamond Town with the bogus letter from Mrs. Casey."

Saxham had thought. He said now:

"This man, this rascally Van Busch, acting as a spy for Brounckers, was disguised as the runner? Is that what has been proved? Did Lady Hannah see the man and recognise him?"

Bingo leaned forward to answer.

"Lady Hannah never set eyes on the man from Diamond Town. But the day the Siege Gazette came out, with a blithering paragraph in it that never ought to have appeared, announcin'"—he coughed and crimsoned—"Lord Beauvayse's formal engagement to Miss Mildare;—my wife was rung up at the Convalescent Hospital by a caller who wouldn't say where he telephoned from. And the message that came through—couched in queer, ambiguous language, and purportin' to come from an old friend—was a message for the young lady who is now Mrs. Saxham!"

Saxham's eyes flickered dangerously. He said not a word. The Major went on:

"My wife didn't then and there identify the voice with Van Busch's. She remembered the name given her as that of the owner of the farm at which Mildare died, a place which by rights was in what's now the Orange River Colony, and not Natal at all. She asked plump and plain: 'Are you So-and-So?' There was no answer to the question. But seven hours later the Mother-Superior was shot; and the nuns and Miss Mildare, on their way to the Convent, were passed by a thickset, bearded man, who ran into one of the Sisters in his hurry, and nearly knocked her down."

"That," said Saxham, "has always been regarded as a suspicious circumstance. But the man was never subsequently traced."

"No! Because," said Bingo, "the runner from Diamond Town evaporated that night."

Saxham said, with his grim under-jaw thrust out:

"Surely that circumstance, when reported to the Officer commanding the Garrison, might then have awakened his suspicions?"

"Naturally," agreed Bingo, "and therefore he kept 'em dark. As for my wife, the shock of the murder, accompanied with her own secret conviction that, in some indirect way, she'd helped to set a malicious, lurking, watchful, dangerous Force of some kind working against your wife—when she dropped that hint I've told you of—bowled her over with a nervous fever."

"I remember," said Saxham, who had been called in.

"Consequently, it wasn't until some days after the Relief—a bare hour or two before the Division—Irregular Horse and Baraland Rifles, and a company or so of Civilian Johnnies that had made believe they were genuine fightin' Tommies till they couldn't get out of the notion—marched out of Gueldersdorp for Frostenberg, that her ladyship got a chance of makin' a clean breast to the Chief. Hold on a minute, Doctor——"

For Saxham would have spoken.

"—The Chief had had his own private opinion, from the very first. He heard what my wife had to say. As you may guess, she'd worked herself up into a regular cooker of remorse and anxiety—told him she was ready to go anywhere and do anything—he'd only got to give her orders, and all that sort of thing! He charged her with the simple but difficult rÔle of holdin' her tongue, and keepin' her oar out, and findin' him—if by good luck she'd got it by her—a specimen of the handwritin' of the clever scoundrel who'd played at bein' a War Intelligence Agent, and waltzed with her five hundred pounds, which sample, as it chanced, she was able to supply. And the fist of the man who'd swindled her, and the writin' of the Mrs. Casey who'd sent a letter per despatch-runner from Diamond Town to a husband who didn't exist, tallied to an upstroke and the crossin' of a 't'!"

"Is it beyond doubt that the letter from the supposed Mrs. Casey was not a genuine communication?" Saxham asked.

"Beyond doubt. As a fact, the neatly-directed envelope had simply got a sheet of blank paper inside. Another odd fact brought to light was, that the person who communicated with my wife at the Convalescent Hospital about half-past twelve on the day of the murder, rang her up on the telephone belongin' to the orderly-room at the Headquarters of the Baraland Rifles. We had up the orderly, and after some solid lyin', he owned that the man from Diamond Town had bribed him with 'baccy to let him put a message through. And that's another link in the evidence, I take it?" said Major Bingo.

"Undoubtedly!"

"There's not much more to tell, except," said Bingo, "that the first march of the Division on its route to Frostenberg led past the Border farm called Haargrond Plaats. It looked deserted and half-ruined, with only a slipshod woman and a coloured man in charge; but something was known of what had gone on there, and might be going on still, and the Boers are clever stage-managers, and it don't do to trust to appearances! So the Chief detached a party with dynamite cartridges and express orders to make the ruin real. Our men searched the place thoroughly before they blew it up; and hidden in a disused chimney—solid bit of old Dutch masonry big enough to accommodate a baker's dozen of sweeps—were a few things calculated to facilitate that search for the needle in the haystack—you understand? Disguises of various kinds—a suit of clothes lined with chamois-leather bags for gold-smugglin'—a good deal of the raw stuff itself, scattered all over the shop by the blow-up—and in a rusty cashbox a diary or private ledger, posted up in a clumsy kind of thieves' cipher, impossible to make out, but with the name written on it of the identical man my wife suspected and the Chief believed to be the murderer of Miss Mildare's adopted mother! And that's what you may call the Clue Direct, Saxham, I rather fancy?"

Major Bingo Wrynche leaned back with an air of some finality, and with some little difficulty extracted a biggish square envelope from the left inner pocket of the accurately-fitting frock-coat. He lightly placed the envelope upon the blotter before Saxham; reached out and took the shiny top-hat off the writing-table, fitted it with peculiar care on his pinkish, sandy, close-cropped head, and said, looking at Saxham with a pleasant smile.

"Perhaps you wouldn't mind throwin' your eye over the contents of that envelope? There are three photographs of handwritin' inside, marked on the backs respectively." He waited for Saxham to take the enclosures from the big envelope, examining the polish of his own varnished patent-leather boots with a fastidious air of anxiety that was extremely well assumed, if it was not strictly genuine. His large face was as bland and expressionless as the face of the grandfather-clock in the Sheraton case that ticked against the wainscot behind him, as he advised:

"Take 'em in numerical sequence. No. 1 is the photographed facsimile of the cover of the bogus letter to Mr. Casey. No. 2"—the speaker lightly touched it with a large round finger-tip—"that's the replica—also photographed—of a card the man we're after wrote on and gave to Lady Hannah, in case she found herself inclined to invest a hundred or so in the kind of wares he professed to supply. Photo No. 3 is a reproduction of an autograph and address that's written on the inside cover of the ledger —posted up in thieves' cipher—that was in the cashbox found at Haargrond Plaats." He waited, screwing painfully at the stiff, waxed ends of the scrubby moustache.

Saxham took the photographs in their order. The envelope of the bogus letter brought by the supposed runner from Diamond Town had been addressed in a big bold black round hand with curiously malformed capitals, to

"Mr. Barney Casey,
"Commercial Traveller,
"Gueldersdorp.
"Care of the Officer Commanding H.M. Forces"

"—Don't put it back in the envelope," said Major Bingo. "Compare the writin' with No. 2."

No. 2 was the photograph of an oblong card. On it was written in ink, in the same bold hand:

"Mr. Hendryk Van Busch,
"C/o Mr. W. Bough,
"Transport Agent,
"Haargrond Plaats,
"Near Matambani,
"Transvaal."
