The Old Man in the Corner Part 4

"The stables, which immediately faced the back entrance of the Phillimore Terrace houses, were all private ones belonging to residents in the neighbourhood. The coachmen, their families, and all the grooms who slept in the stablings were rigidly watched and questioned. One and all had seen nothing, heard nothing, until Robertson's shrieks had roused them from their sleep.

"As for the letter from Brighton, it was absolutely commonplace, and written upon note-paper which the detective, with Machiavellian cunning, traced to a stationer's shop in West Street. But the trade at that particular shop was a very brisk one; scores of people had bought note-paper there, similar to that on which the supposed doctor had written his tricky letter. The handwriting was cramped, perhaps a disguised one; in any case, except under very exceptional circ.u.mstances, it could afford no clue to the ident.i.ty of the thief. Needless to say, the tramp, when told to write his name, wrote a totally different and absolutely uneducated hand.

"Matters stood, however, in the same persistently mysterious state when a small discovery was made, which suggested to Mr. Francis Howard an idea, which, if properly carried out, would, he hoped, inevitably bring the cunning burglar safely within the grasp of the police.

"That was the discovery of a few of Mr. Knopf's diamonds," continued the man in the corner after a slight pause, "evidently trampled into the ground by the thief whilst making his hurried exit through the garden of No. 22, Phillimore Terrace.

"At the end of this garden there is a small studio which had been built by a former owner of the house, and behind it a small piece of waste ground about seven feet square which had once been a rockery, and is still filled with large loose stones, in the shadow of which earwigs and woodlice innumerable have made a happy hunting ground.

"It was Robertson who, two days after the robbery, having need of a large stone, for some household purpose or other, dislodged one from that piece of waste ground, and found a few s.h.i.+ning pebbles beneath it. Mr. Knopf took them round to the police-station himself immediately, and identified the stones as some of his Parisian ones.

"Later on the detective went to view the place where the find had been made, and there conceived the plan upon which he built big cherished hopes.

"Acting upon the advice of Mr. Francis Howard, the police decided to let the anonymous tramp out of his safe retreat within the station, and to allow him to wander whithersoever he chose. A good idea, perhaps-the presumption being that, sooner or later, if the man was in any way mixed up with the cunning thieves, he would either rejoin his comrades or even lead the police to where the remnant of his h.o.a.rd lay hidden; needless to say, his footsteps were to be literally dogged.

"The wretched tramp, on his discharge, wandered out of the yard, wrapping his thin coat round his shoulders, for it was a bitterly cold afternoon. He began operations by turning into the Town Hall Tavern for a good feed and a copious drink. Mr. Francis Howard noted that he seemed to eye every pa.s.ser-by with suspicion, but he seemed to enjoy his dinner, and sat some time over his bottle of wine.

"It was close upon four o'clock when he left the tavern, and then began for the indefatigable Mr. Howard one of the most wearisome and uninteresting chases, through the mazes of the London streets, he ever remembers to have made. Up Notting Hill, down the slums of Notting Dale, along the High Street, beyond Hammersmith, and through Shepherd's Bush did that anonymous tramp lead the unfortunate detective, never hurrying himself, stopping every now and then at a public-house to get a drink, whither Mr. Howard did not always care to follow him.

"In spite of his fatigue, Mr. Francis Howard's hopes rose with every half-hour of this weary tramp. The man was obviously striving to kill time; he seemed to feel no weariness, but walked on and on, perhaps suspecting that he was being followed.

"At last, with a beating heart, though half perished with cold, and with terribly sore feet, the detective began to realize that the tramp was gradually working his way back towards Kensington. It was then close upon eleven o'clock at night; once or twice the man had walked up and down the High Street, from St. Paul's School to Derry and Toms' shops and back again, he had looked down one or two of the side streets and-at last-he turned into Phillimore Terrace. He seemed in no hurry, he oven stopped once in the middle of the road, trying to light a pipe, which, as there was a high east wind, took him some considerable time. Then he leisurely sauntered down the street, and turned into Adam and Eve Mews, with Mr. Francis Howard now close at his heels.

"Acting upon the detective's instructions, there were several men in plain clothes ready to his call in the immediate neighbourhood. Two stood within the shadow of the steps of the Congregational Church at the corner of the mews, others were stationed well within a soft call.

"Hardly, therefore, had the hare turned into the cul-de-sac at the back of Phillimore Terrace than, at a slight sound from Mr. Francis Howard, every egress was barred to him, and he was caught like a rat in a trap.

"As soon as the tramp had advanced some thirty yards or so (the whole length of this part of the mews is about one hundred yards) and was lost in the shadow, Mr. Francis Howard directed four or five of his men to proceed cautiously up the mews, whilst the same number were to form a line all along the front of Phillimore Terrace between the mews and the High Street.

"Remember, the back-garden walls threw long and dense shadows, but the silhouette of the man would be clearly outlined if he made any attempt at climbing over them. Mr. Howard felt quite sure that the thief was bent on recovering the stolen goods, which, no doubt, he had hidden in the rear of one of the houses. He would be caught in flagrante delicto, and, with a heavy sentence hovering over him, he would probably be induced to name his accomplice. Mr. Francis Howard was thoroughly enjoying himself.

"The minutes sped on; absolute silence, in spite of the presence of so many men, reigned in the dark and deserted mews.

"Of course, this night's adventure was never allowed to get into the papers," added the man in the corner with his mild smile. "Had the plan been successful, we should have heard all about it, with a long eulogistic article as to the astuteness of our police; but as it was-well, the tramp sauntered up the mews-and-there he remained for aught Mr. Francis Howard or the other constables could ever explain. The earth or the shadows swallowed him up. No one saw him climb one of the garden walls, no one heard him break open a door; he had retreated within the shadow of the garden walls, and was seen or heard of no more."

"One of the servants in the Phillimore Terrace houses must have belonged to the gang," said Polly with quick decision.

"Ah, yes! but which?" said the man in the corner, making a beautiful knot in his bit of string. "I can a.s.sure you that the police left not a stone unturned once more to catch sight of that tramp whom they had had in custody for two days, but not a trace of him could they find, nor of the diamonds, from that day to this."

CHAPTER VI

ALL HE KNEW

"The tramp was missing," continued the man in the corner, "and Mr. Francis Howard tried to find the missing tramp. Going round to the front, and seeing the lights at No. 26 still in, he called upon Mr. s.h.i.+pman. The jeweller had had a few friends to dinner, and was giving them whiskies-and-sodas before saying good night. The servants had just finished was.h.i.+ng up, and were waiting to go to bed; neither they nor Mr. s.h.i.+pman nor his guests had seen or heard anything of the suspicious individual.

"Mr. Francis Howard went on to see Mr. Ferdinand Knopf. This gentleman was having his warm bath, preparatory to going to bed. So Robertson told the detective. However, Mr. Knopf insisted on talking to Mr. Howard through his bath-room door. Mr. Knopf thanked him for all the trouble he was taking, and felt sure that he and Mr. s.h.i.+pman would soon recover possession of their diamonds, thanks to the persevering detective.

"He! he! he!" laughed the man in the corner. "Poor Mr. Howard. He persevered-but got no farther; no, nor anyone else, for that matter. Even I might not be able to convict the thieves if I told all I knew to the police.

"Now, follow my reasoning, point by point," he added eagerly.

"Who knew of the presence of the diamonds in the house of Mr. s.h.i.+pman and Mr. Knopf? Firstly," he said, putting up an ugly claw-like finger, "Mr. s.h.i.+pman, then Mr. Knopf, then, presumably, the man Robertson."

"And the tramp?" said Polly.

"Leave the tramp alone for the present since he has vanished, and take point number two. Mr. s.h.i.+pman was drugged. That was pretty obvious; no man under ordinary circ.u.mstances would, without waking, have his keys abstracted and then replaced at his own bedside. Mr. Howard suggested that the thief was armed with some anaesthetic; but how did the thief get into Mr. s.h.i.+pman's room without waking him from his natural sleep? Is it not simpler to suppose that the thief had taken the precaution to drug the jeweller before the latter went to bed?"

"But-"

"Wait a moment, and take point number three. Though there was every proof that Mr. s.h.i.+pman had been in possession of 25,000 worth of goods since Mr. Knopf had a cheque from him for that amount, there was no proof that in Mr. Knopf's house there was even an odd stone worth a sovereign.

"And then again," went on the scarecrow, getting more and more excited, "did it ever strike you, or anybody else, that at no time, while the tramp was in custody, while all that searching examination was being gone on with, no one ever saw Mr. Knopf and his man Robertson together at the same time?

"Ah!" he continued, whilst suddenly the young girl seemed to see the whole thing as in a vision, "they did not forget a single detail-follow them with me, point by point. Two cunning scoundrels-geniuses they should be called-well provided with some ill-gotten funds-but determined on a grand coup. They play at respectability, for six months, say. One is the master, the other the servant; they take a house in the same street as their intended victim, make friends with him, accomplish one or two creditable but very small business transactions, always drawing on the reserve funds, which might even have amounted to a few hundreds-and a bit of credit.

"Then the Brazilian diamonds, and the Parisians-which, remember, were so perfect that they required chemical testing to be detected. The Parisian stones are sold-not in business, of course-in the evening, after dinner and a good deal of wine. Mr. Knopf's Brazilians were beautiful; perfect! Mr. Knopf was a well-known diamond merchant.

"Mr. s.h.i.+pman bought-but with the morning would have come sober sense, the cheque stopped before it could have been presented, the swindler caught. No! those exquisite Parisians were never intended to rest in Mr. s.h.i.+pman's safe until the morning. That last bottle of '48 port, with the aid of a powerful soporific, ensured that Mr. s.h.i.+pman would sleep undisturbed during the night.

"Ah! remember all the details, they were so admirable! the letter posted in Brighton by the cunning rogue to himself, the smashed desk, the broken pane of gla.s.s in his own house. The man Robertson on the watch, while Knopf himself in ragged clothing found his way into No. 26. If Constable D 21 had not appeared upon the scene that exciting comedy in the early morning would not have been enacted. As it was, in the supposed fight, Mr. s.h.i.+pman's diamonds pa.s.sed from the hands of the tramp into those of his accomplice.

"Then, later on, Robertson, ill in bed, while his master was supposed to have returned-by the way, it never struck anybody that no one saw Mr. Knopf come home, though he surely would have driven up in a cab. Then the double part played by one man for the next two days. It certainly never struck either the police or the inspector. Remember they only saw Robertson when in bed with a streaming cold. But Knopf had to be got out of gaol as soon as possible; the dual role could not have been kept up for long. Hence the story of the diamonds found in the garden of No. 22. The cunning rogues guessed that the usual plan would be acted upon, and the suspected thief allowed to visit the scene where his h.o.a.rd lay hidden.

"It had all been foreseen, and Robertson must have been constantly on the watch. The tramp stopped, mind you, in Phillimore Terrace for some moments, lighting a pipe. The accomplice, then, was fully on the alert; he slipped the bolts of the back garden gate. Five minutes later Knopf was in the house, in a hot bath, getting rid of the disguise of our friend the tramp. Remember that again here the detective did not actually see him.

"The next morning Mr. Knopf, black hair and beard and all, was himself again. The whole trick lay in one simple art, which those two cunning rascals knew to absolute perfection, the art of impersonating one another.

"They are brothers, presumably-twin brothers, I should say."

"But Mr. Knopf-" suggested Polly.

"Well, look in the Trades' Directory; you will see F. Knopf & Co., diamond merchants, of some City address. Ask about the firm among the trade; you will hear that it is firmly established on a sound financial basis. He! he! he! and it deserves to be," added the man in the corner, as, calling for the waitress, he received his ticket, and taking up his shabby hat, took himself and his bit of string rapidly out of the room.
