Fenley was frowning when he reappeared.

"Another call from the Bank," he said gruffly. "Everything there is at sixes and sevens since the news was howled through the City. That is why I really must go to town later. I'm not altogether sorry. The necessity of bringing my mind to bear on business will leaven the surfeit of horrors I've borne this morning....

"Now, about my brother, Mr. Winter. While listening to Mr. Brown's condolences—you remember Brown, the cashier, Mr. Furneaux—I was thinking of more vital matters. A policy of concealment often defeats its own object, and I have come to the conclusion that you ought to know of a dispute between my father and Robert. There's a woman in the case, of course. It's a rather unpleasant story, too. Poor Bob got entangled with a married woman some months ago. He was infatuated at first, but would have broken it off recently were it not for fear of divorce proceedings."

"Would you make the position a little clearer, sir?" said Winter, who also was listening and thinking. He was quite certain that when he met Mr. Brown he would meet the man who had been worrying a telephone exchange "during the last twenty minutes."

"I—I can't." And Fenley's hand brushed away some imaginary film from before his eyes. "Bob and I never hit it off very well. We're only half brothers, you see."

"Was your father married twice?"

"Am I to reopen a forgotten history?"

"Some person, or persons, may not have forgotten it."

"Well, you must have the full story, if at all. My father was not a well-born man. Thirty years ago he was a trainer in the service of a rich East Indian merchant, Anthony Drummond, of Calcutta, who owned racehorses, and one of Drummond's daughters fell in love with him. They ran away and got married, but the marriage was a failure. She divorced him—by mutual consent, I fancy. Anyhow, I was left on his hands.

"He went to Assam, and fell in with a tea planter named Manning, who had a big estate, but neglected it for racing. My father suddenly developed business instincts and Manning made him a partner. Unfortunately—well, that is a hard word, but it applies—my father married again—a girl of his own class; rather beneath it, in fact. Then Bob was born.

"The old man made money, heaps of it. Manning married, but lost his wife when Sylvia came into the world. That broke him up; he drank himself to death, leaving his partner as trustee and guardian for the infant. There was a boom in tea estates; my father sold on the crest of the wave and came to London. He progressed, but Mrs. Fenley—didn't. She was just a Tommy's daughter, and never seemed to try and rise above the level of 'married quarters'.

"I had to mind my p's and q's as a boy, I can assure you. My mother was always thrown in my teeth. Mrs. Fenley called her 'black.' It was a —— lie. She was dark-skinned, as I am, but there are Cornish and Welsh folk of much darker complexion. My father, too, shared something of the same prejudice. I had to be the good boy of the family. Otherwise, I should have been turned out, neck and crop.

"As I behaved well, he was forced to depend on me, because Bob did as he liked, with his mother always ready to aid and abet him. Then came this scrape I've spoken of. I believe Bob was being blackmailed. That's the long and the short of it. Now you know the plain, ungarbled facts. Better that they should come from me than reach you with the decorations of gossip and servants' tittle-tattle."

The somewhat strained and metallic voice ceased. Fenley was seated at the corner of the table near the door. Seemingly yielding to that ever-present desire for movement, he pushed with his foot an armchair out of its place at the head of the table.

Sylvia Manning had pointed out that chair to Furneaux as the one occupied by Mortimer Fenley at breakfast.

"Is the first Mrs. Fenley dead?" said Furneaux suddenly.

"I don't think so," said Fenley, after a pause.

"You are not sure?"

"No."

"Have you ever tried to find out?"

"No, I dare not."

"May I ask why?"

"If it were discovered that my mother and I were in communication I would have been given short shrift in the bank."

"Did she marry again?"

"I don't know."

Again there was silence. Furneaux seemed to be satisfied that he was following a blind alley, and Winter became the inquisitor.

"What is the name of the woman with whom your brother is mixed up?"

"I can not tell you, but my father knew."

"What leads you to form that opinion?"

"Some words that passed between Bob and him last Saturday morning."

"Where? Here?"

"Yes, in the hall. Tomlinson heard more distinctly than I. I saw there was trouble brewing, and kept out of it—hung back, on the pretense of reading a newspaper."

"As to the missing rifle—can you help us there?"

"Not in the least. I wish to Heaven Bob had gone to Africa, as he was planning. Then all this misery would have been avoided."

"Do you mean your father's death?"

Fenley started. He had not weighed his words.

"Oh, no, no!" he cried hurriedly. "Don't try to trip me into admissions, Mr. Winter. I can't stand that, damned if I can."

He jumped up, went to the sideboard and mixed himself a weak brandy and soda, which he swallowed as if his throat were afire with thirst.

"I am not treating you as a hostile witness, sir," answered Winter calmly. "Mr. Furneaux and I are merely clearing the ground. Soon we shall know, or believe that we know, what line to avoid and what to follow."

"Is Miss Sylvia Manning engaged to be married?" put in Furneaux. Fenley gave him a fiendish look.

"What the devil has Miss Manning's matrimonial prospects got to do with this inquiry?" he said, and the venom in his tone was hardly to be accounted for by Furneaux's harmless-sounding query.

"One never knows," said the little man, taking the unexpected attack with bland indifference. "You don't appreciate our position in this matter. We are not judges, but guessers. We sit in the stalls of a theater, watching people on the stage of real life playing four acts of a tragedy, and it is our business to construct the fifth, which is produced in court. Let me give you a wildly supposititious version of that fifth act now. Suppose some neurotic fool was in love with Miss Manning, or her money, and Mr. Mortimer Fenley opposed the project. That would supply a motive for the murder. Do you take the point?"

"I'm sorry I blazed out at you. Miss Manning is not engaged to be married, nor likely to be for many a day."

Now, the obvious question was, "Why, she being such an attractive young lady?" But Furneaux never put obvious questions. He turned to Winter with the air of one who had nothing more to say. His colleague was evidently perplexed, and showed it, but extricated the others from an awkward situation with the tact for which he was noted.

"I am much obliged to you for your candor in supplying such a clear summary of the family history, Mr. Fenley," he said. "Of course, we shall be meeting you frequently during the next few days, and developments can be discussed as they arise."

His manner, more than his words, conveyed an intimation that when the opportunity served he would trounce Furneaux for an indiscretion. Fenley was mollified.

"Command me in every way," he said.

"There is one more question, the last and the gravest," said Winter seriously. "Do you suspect any one of committing this murder?"

"No! On my soul and honor, no!"

"Thank you, sir. We'll tackle the butler now, if you please."

"I'll send him," said Fenley. Probably in nervous forgetfulness, he lighted a cigarette and went out, blowing two long columns of smoke through his nostrils. He might, or might not, have been pleased had he heard the reprimanding of Furneaux.

"Good stroke, that about the stage, Charles," mumbled Winter. Furneaux threw out his hands with a gesture of disgust.

"What an actor the man is!" he almost hissed, owing to the need there was of subduing his piping voice to a whisper. "Every word thought out, but allowed to be dragged forth reluctantly. Putting brother Bob into the tureen, isn't he? 'On my soul and honor,' too! Don't you remember, some French blighter said that when an innocent man was being made a political scapegoat?... Of course, the mother is a Eurasian, and he has met her. A nice dish he served up! A salad of easily ascertainable facts with a dressing of lying innuendo. Name of a pipe! If Master Hilton hadn't been in the house——"

A knock, and the door opened.

"You want me, gentlemen, I am informed by Mr. Hilton Fenley," said Tomlinson.

There spoke the butler, discreet, precise, incapable of error. Tomlinson had recovered his breath and his dignity. He was in his own domain. The very sight of the Mid-Victorian furniture gave him confidence. His skilled glance traveled to the decanter and the empty glass. He knew to a minim how much brandy had evaporated since his last survey of the sideboard.

"Sit down, Tomlinson," said Winter pleasantly. "You must have been dreadfully shocked by this morning's occurrence."

Tomlinson sat down. He drew the chair somewhat apart from the table, knowing better than to place his elbows on that sacred spread of polished mahogany.

"I was, sir," he admitted. "Indeed, I may say I shall always be shocked by the remembrance of it."

"Mr. Mortimer Fenley was a kindly employer?"

"One of the best, sir. He liked things done just so, and could be sharp if there was any laxity, but I have never received a cross word from him."

"Known him long?"

"Ever since he come to The Towers; nearly twenty years."

"And Mrs. Fenley?"

"Mrs. Fenley leaves the household entirely under my control, sir. She never interferes."

"Why?"

"She is an invalid."

"Is she so ill that she can not be seen?"

"Practically that, sir."

"Been so for twenty years?"

Tomlinson coughed. He was prepared with an ample statement as to the catastrophe which took place at nine thirty a. m., but this delving into bygone decades was unexpected and decidedly distasteful, it would seem.

"Mrs. Fenley is unhappily addicted to the drug habit, sir," he said severely, plainly hinting that there were bounds, even for detectives.

"I fancied so," was the dry response. "However, I can understand and honor your reluctance to reveal Mrs. Fenley's failings. Now, please tell us exactly what Mr. Fenley and Mr. Robert said to each other in the hall last Saturday morning."

How poor Farrow, immured in his jungle, would have gloated over Tomlinson's collapse when he heard those fatal words! To his credit be it said, the butler had not breathed a word to a soul concerning the scene between father and son. He knew nothing of an inquisitive housemaid, and his tortured brain fastened on Hilton Fenley as the Paul Pry. Unconsciously, he felt bitter against his new master from that moment.

"Must I go into these delicate matters, sir?" he bleated.

"Most certainly. The man whom you respected so greatly has been killed, not in the course of a heated dispute, but as the outcome of a brutal and well-conceived plan. Bear that in mind, and you will see that concealment of vital facts is not only unwise but disloyal."

Winter rather let himself go in his earnestness. He flushed slightly, and dared not look at Furneaux lest he should encounter an admiring glance.

The butler, however, was far too worried to pay heed to his questioner's florid turn of speech. He sighed deeply. He felt like a timid swimmer in a choppy sea, knowing he was out of his depth yet compelled to struggle blindly.

So, with broken utterance, he repeated the words which a rabbit-eared housemaid had carried to Bates. Nevertheless, even while he labored on, he fancied that the detectives did not attach such weight to the recital as he feared. He anticipated that Winter would write each syllable in a notebook, and show an exceeding gravity of appreciation. To his great relief, nothing of the kind happened. Winter's comment was distinctly helpful.

"It must have been rather disconcerting for you to hear father and son quarreling openly," he said.

"Sir, it was most unpleasant."

"Now, did you form any opinion as to the cause of this bickering? For instance, did you imagine that Mr. Fenley wished his son to break off relations with an undesirable acquaintance?"

"I did, sir."

"Is either Mr. Hilton or Mr. Robert engaged to be married? Or, I had better put it, had their father expressed any views as to either of his sons marrying suitably?"

"We, in the house, sir, had a notion that Mr. Fenley would like Mr. Robert to marry Miss Sylvia."

"Exactly. I expected that. Were these two young people of the same way of thinking?"

"They were friendly, sir, but more like brother and sister. You see, they were reared together. It often happens that way when a young gentleman and young lady grow up from childhood in each other's company. They never think of marriage, whereas the same young gentleman would probably fall head over heels in love with the same young lady if he met her elsewhere."

"Good!" broke in Furneaux. "Tomlinson, do you drink port?"

The butler looked his astonishment, but answered readily enough—

"My favorite wine, sir."

"I thought so. Taken in moderation, port induces sound reasoning. I have some Alto Douro of '61. I'll bring you a bottle."

Tomlinson was mystified, a trifle scandalized perhaps; but he bowed his acknowledgments.

"Sir, I will appreciate it greatly."

"I know you will. My Alto Douro goes down no gullet but a connoisseur's."

Even in his agitation, Tomlinson smiled.

What a queer little man this undersized detective was, to be sure, and how oddly he expressed himself!

"I ask this just as a matter of form, but did Mr. Robert Fenley take his .450 Express rifle when he went away on Saturday?" said Winter.

"No, sir. He had only a valise strapped to the carrier. But I do happen to know that the gun was in his room on Friday, because Friday is my day for house inspection."

"Any cartridges?"

"I can't say, sir. They would be in a drawer, or, more likely, in the gun room."

"Where is this gun room?"

"Next to the harness room, sir—second door to the right in the courtyard."

"Speaking absolutely in confidence, have you formed a theory as to this murder?"

"No, sir. But if any sort of evidence is piled up against Mr. Robert I shall not credit it. No power on earth could make me believe that he would kill his father in cold blood. He respected his father, sir. He's a bit wild, as young men with too much money are apt to be, but he was good-hearted and genuine."

"Yet he did speak of blowing his own brains out, and his father's."

"That was his silly way of talking, sir. He would say, 'Tomlinson, if you tell the pater what time I came home last night I'll stab you to the heart.' When there was a bit of a family squabble he would threaten to mix a gallon of weed-killer and drink every drop. Everything was rotten, or beastly, or awfully ripping. He was not so well educated as he ought to have been—Mrs. Fenley's fault entirely; and he hadn't the—the words——"

"The vocabulary."

"That's it, sir. I see you understand."

"Tomlinson," interrupted Furneaux, "a famous American writer, Oliver Wendell Holmes, described adjectives of that class as the blank checks of intellectual bankruptcy. You have hit on the same great thought."

The butler smiled again. He was beginning to like Furneaux.

"You have never heard, I suppose, of Mr. Fenley receiving any threatening letters?" continued Winter.

"No, sir. Some stupid postcards were sent when he tried to close a right of way through the park; but they were merely ridiculous, and that occurred years ago."

"So you, like the rest of us, feel utterly unable to assign a motive for this crime?"

"Sir, it's like a thunderbolt from a clear sky."

"Were the brothers, or half brothers, on good terms with each other?"

Tomlinson started at those words, "or half brothers." He was not prepared for the Superintendent's close acquaintance with the Fenley records.

"They're as different as chalk and cheese, sir," he said, after a pause to collect his wits. "Mr. Hilton is clever and well read, and cares nothing about sport, though he has a wonderful steady nerve. Yes, I mean that——" for Winter's prominent eyes showed surprise at the statement. "He's a strange mixture, is Mr. Hilton. He's a fair nailer with a revolver. I've seen him hit a penny three times straight off at twelve paces, and, when in the mind, he would bowl over running rabbits with a rook rifle. Yet he never joined the shooting parties in October. Said it made him ill to see graceful birds shattered by clumsy folk. All the same, he would ill-treat a horse something shameful. I——"

The butler bethought himself, and pulled up with a jerk. But Winter smiled encouragingly.

"Say what you had in mind," he said. "You are not giving evidence. You may rely on our discretion."

"Well, sir, he's that sort of man who must have his own way, and when things went against him at home, he'd take it out of any servant or animal that vexed him afterwards."

"It was not an ideally happy household, I take it?"

"Things went along very smoothly, sir, all things considered. They have been rather better since Miss Sylvia came home from Brussels. She was worried about Mrs. Fenley at first, but gave it up as a bad job; and Mr. Fenley and the young gentlemen used to hide their differences before her. That was why Mr. Fenley and Mr. Robert blazed up in the hall on Saturday. They couldn't say a word in front of Miss Sylvia at the breakfast table."

"The four always met at breakfast, then?"

"Almost without fail, sir. On Monday and Tuesday mornings Mr. Hilton breakfasted early, and his father was joking about it, for if any one was late it would be him—or should I say 'he', sir?"

Furneaux cackled.

"I wouldn't have you alter your speech on any account," he grinned. "Why did Mr. Hilton turn over these new leaves on Monday and Tuesday?"

"He said he had work to do. What it was I don't know, sir. But he managed to miss the nine forty-five, and Mr. Fenley was vexed about it. Of course, I don't know why I am telling you these small things. Mr. Hilton might be angry——"

Some one knocked. Harris, the footman, entered, a scared look on his face.

"Can you come a moment, Mr. Tomlinson?" he said. "The undertaker is here for the body."

"What is that?" cried Winter sharply.

The butler arose.

"Didn't Mr. Hilton mention it, sir?" he said. "Dr. Stern must hold a post mortem before the inquest, and he suggested that it could be carried through more easily in the mortuary attached to the Cottage Hospital. Isn't that all right, sir?"

"Oh, yes, I'm sorry. I didn't understand. Go, by all means. We'll wait here."

When they were alone, the two detectives remained silent for a long minute. Winter arose and looked through a window at the scene outside. A closed hearse had arrived; some men were carrying in a rough coffin and three trestles. There was none of the gorgeous trappings which lend dignity to such transits in public. Polished oak and gleaming brass and rare flowers would add pageantry later; this was the livery of the dissecting-room.

"Queer case!" growled Winter over his shoulder.

"If only Hilton had breakfasted early this morning!" said Furneaux.

"If the dog hadn't stopped to scratch himself he would have caught the hare," was the irritable answer.

"Aren't you pleased with Tomlinson, then?"

"The more he opened up the more puzzled I became. By the way, you hardly asked him a thing, though you were keen on tackling him yourself."

"James, I'm an artist. You handled him so neatly that I stood by and appreciated. It would be mean to suggest that the prospect of a bottle of Alto Douro quickened his imagination. I——"

Winter's hands were crossed behind his back, and his fingers worked in expressive pantomime. Furneaux was by his side in an instant. Hilton Fenley was standing on the steps, a little below and to the left of the window. He was gazing with a curiously set stare at the bust of Police Constable Farrow perched high among the trees to the right. The observers in the room had then an excellent opportunity to study him at leisure.

"More of Asia than of Europe in that face and figure," murmured Furneaux.

"The odd thing is that he should be more interested in our sentinel than in the disposal of his father's body," commented Winter.

"A live donkey is always more valuable than a dead lion."

"We shall have to go to that wood soon, Charles."

"Your only failing is that you can't see the forest for the trees."

They were bickering, an ominous sign for some one yet unknown. Suddenly, far down the avenue, they saw a motor bicycle traveling fast. Hilton Fenley saw it at the same moment and screened his eyes with a hand, for he was bareheaded and the sun was now blazing with noonday intensity.

"Brother Bob!" hissed Furneaux.

Winter thought the other had recognized the man crouched over the handlebar.

"Gee!" he said. "Your sight must be good."

"I'm not using eyes, but brains. Who else can it be? This is the psychological moment which never fails. Bet you a new hat I'm right."

"I'm not buying you any new hats," said Winter. "Look at Hilton. He knows. Now, I wonder if the other one telephoned. No. He'd have told us. He'd guess it would crop up in talk some time or other. Yes, the motorist is waving to him. There! You can see his face. It is Robert, isn't it?"

"O sapient one!" snapped Furneaux.

The meeting between the brothers was orthodox in its tragic friendliness. The onlookers could supply the words they were unable to hear. Robert Fenley, bigger, heavier, altogether more British in build and semblance than Hilton, was evidently asking breathlessly if the news he had read in London was true, and Hilton was volubly explaining what had happened, pointing to the wood, the doorway, the hearse, emphasizing with many gestures the painful story he had to tell.

Then the two young men mounted the steps, the inference being that Robert Fenley wished to see his father's body before it was removed. A pallor was spreading beneath the glow on the younger Fenley's perspiring face. He was obviously shocked beyond measure. Grief and horror had imparted a certain strength to somewhat sullen features. He might be a ne'er-do-well, a loose liver, a good deal of a fool, perhaps, but he was learning one of life's sharpest lessons; in time, it might bring out what was best in his character. The detectives understood now why the butler, who knew the boy even better than his own father, deemed it impossible that he should be a parricide. Some men are constitutionally incapable of committing certain crimes. At least, the public thinks so; Scotland Yard knows better, and studies criminology with an open mind.

The brothers had hardly crossed the threshold of the house when an eldritch scream rang through the lofty hall. The detectives hastened from the dining-room, and forthwith witnessed a tableau which would have received the envious approval of a skilled producer of melodrama. The hall measured some thirty-five feet square, and was nearly as lofty, its ceiling forming the second floor. The staircase was on the right, starting from curved steps in the inner right angle and making a complete turn from a half landing to reach a gallery which ran around three sides of the first floor. The fourth contained the doorway, with a window on each hand and four windows above.

The stairs and the well of the hall were of oak, polished as to parquet and steps, but left to age and color naturally as to wainscot, balusters and rails. The walls of the upper floor were decorated in shades of dull gold and amber. The general effect was superb, either in daylight or when a great Venetian luster in the center of the ceiling blazed with electric lights.

The body of the unfortunate banker had not been removed from the oaken settee at the back of the hall, and was still covered with a white sheet. An enormously stout woman, clothed in a dressing-gown of black lace, was standing in the cross gallery and resisting the gentle efforts of Sylvia Manning, now attired in black, to take her away. The stout woman's face was deathly white, and her distended eyes were gazing dully at the ominous figure stretched beneath. Two podgy hands, with rings gleaming on every finger, were clutching the carved railing, and the tenacity of their grip caused the knuckles to stand out in white spots on the ivory-tinted skin.

This, then, was Mrs. Fenley, in whom some vague stirring of the spirit had induced a consciousness that all was not well in the household with which she "never interfered."

It was she who had uttered that ringing shriek when some flustered maid blurted out that "the master" was dead, and her dazed brain had realized what the sheet covered. She lifted her eyes from that terrifying object when her son entered with Hilton Fenley.

"Oh, Bob!" she wailed. "They've killed your father! Why did you let them do it?"

Even in the agony of the moment the distraught young man was aware that his mother was in no fit state to appear thus openly.

"Mother," he said roughly, "you oughtn't to be here, you know. Do go to your room with Sylvia. I'll come soon, and explain everything."

"Explain!" she wailed. "Explain your father's death! Who killed him? Tell me that, and I'll tear them with my nails. But is he dead? Did that hussy lie to me? You all tell me lies because you think I am a fool. Let me alone, Sylvia. I will go to my husband. Let me alone, or I'll strike you!"

By sheer weight she forced herself free from the girl's hands, and tottered down the stairs. At the half landing she fell to her knees, and Sylvia ran to pick her up. Then Hilton Fenley seemed to arouse himself from a stupor. Flinging a command at the servants, he rushed to Sylvia's assistance, and, helped by Tomlinson and a couple of footmen, half carried the screaming and fighting woman up the stairs and along a corridor.

Thus it happened that Robert Fenley was left in the hall with the dead body of his father. He stood stock still, and seemed to follow with disapproval the manner of the disappearance of the poor creature whom he called mother. Her shrieks redoubled in volume as she understood that she would not be allowed to see her husband's corpse, and her son added to the uproar by shouting loudly:

"Hi, there! Don't ill-treat her, or I'll break all your —— necks! Confound you, be gentle with her!"

He listened till a door slammed, and a sudden cessation of the tumult showed that some one, in sheer self-defense, had given her morphia, the only sedative that could have any real effect. Then he turned, and became aware of the presence of the two detectives.

"Well," he said furiously, "who are you, and what the blazes do you want here? Get out, both of you, or I'll have you chucked out!"
