“Convinced that something was amiss with him, she rushed down the steps – for the house was none other than the opium den in which you found me to-night – and running through the front room she attempted to ascend the stairs which led to the first floor. At the foot of the stairs, however, she met this Lascar scoundrel of whom I have spoken, who thrust her back and, aided by a Dane, who acts as assistant there, pushed her out into the street. Filled with the most maddening doubts and fears, she rushed down the lane and, by rare good-fortune, met in Fresno Street a number of constables with an inspector, all on their way to their beat. The inspector and two men accompanied her back, and in spite of the continued resistance of the proprietor, they made their way to the room in which Mr. St. Clair had last been seen. There was no sign of him there. In fact, in the whole of that floor there was no one to be found save a crippled wretch of hideous aspect, who, it seems, made his home there. Both he and the Lascar stoutly swore that no one else had been in the front room during the afternoon. So determined was their denial that the inspector was staggered, and had almost come to believe that Mrs. St. Clair had been deluded when, with a cry, she sprang at a small deal box which lay upon the table and tore the lid from it. Out there fell a cascade of children’s bricks. It was the toy which he had promised to bring home.

“This discovery, and the evident confusion which the cripple showed, made the inspector realise that the matter was serious. The rooms were carefully examined, and results all pointed to an abominable crime. The front room was plainly furnished as a sitting-room and led into a small bedroom, which looked out upon the back of one of the wharves. Between the wharf and the bedroom window is a narrow strip, which is dry at low tide but is covered at high tide with at least four and a half feet of water. The bedroom window was a broad one and opened from below. On examination traces of blood were to be seen upon the windowsill, and several scattered drops were visible upon the wooden floor of the bedroom. Thrust away behind a curtain in the front room were all the clothes of Mr. Neville St. Clair, with the exception of his coat. His boots, his socks, his hat, and his watch – all were there. There were no signs of violence upon any of these garments, and there were no other traces of Mr. Neville St. Clair. Out of the window he must apparently have gone for no other exit could be discovered, and the ominous bloodstains upon the sill gave little promise that he could save himself by swimming, for the tide was at its very highest at the moment of the tragedy.

“And now as to the villains who seemed to be immediately implicated in the matter. The Lascar was known to be a man of the vilest antecedents, but as, by Mrs. St. Clair’s story, he was known to have been at the foot of the stair within a very few seconds of her husband’s appearance at the window, he could hardly have been more than an accessory to the crime. His defence was one of absolute ignorance, and he protested that he had no knowledge as to the doings of Hugh Boone, his lodger, and that he could not account in any way for the presence of the missing gentleman’s clothes.

“So much for the Lascar manager. Now for the sinister cripple who lives upon the second floor of the opium den, and who was certainly the last human being whose eyes rested upon Neville St. Clair. His name is Hugh Boone, and his hideous face is one which is familiar to every man who goes much to the City. He is a professional beggar, though in order to avoid the police regulations he pretends to a small trade in wax vestas[58]. Some little distance down Threadneedle Street, upon the left-hand side, there is, as you may have remarked, a small angle in the wall. Here it is that this creature takes his daily seat, cross-legged with his tiny stock of matches on his lap, and as he is a piteous spectacle a small rain of charity descends into the greasy leather cap which lies upon the pavement beside him. I have watched the fellow more than once before ever I thought of making his professional acquaintance, and I have been surprised at the harvest which he has reaped in a short time. His appearance, you see, is so remarkable that no one can pass him without observing him. A shock of orange hair, a pale face disfigured by a horrible scar, which, by its contraction, has turned up the outer edge of his upper lip, a bulldog chin, and a pair of very penetrating dark eyes, which present a singular contrast to the colour of his hair, all mark him out from amid the common crowd of mendicants and so, too, does his wit, for he is ever ready with a reply to any piece of chaff which may be thrown at him by the passers-by. This is the man whom we now learn to have been the lodger at the opium den, and to have been the last man to see the gentleman of whom we are in quest.”

“But a cripple!” said I. “What could he have done single-handed against a man in the prime of life?”

“He is a cripple in the sense that he walks with a limp; but in other respects he appears to be a powerful and well-nurtured man. Surely your medical experience would tell you, Watson, that weakness in one limb is often compensated for by exceptional strength in the others.”

“Pray continue your narrative.”

“Mrs. St. Clair had fainted at the sight of the blood upon the window, and she was escorted home in a cab by the police, as her presence could be of no help to them in their investigations. Inspector Barton, who had charge of the case, made a very careful examination of the premises, but without finding anything which threw any light upon the matter. One mistake had been made in not arresting Boone instantly, as he was allowed some few minutes during which he might have communicated with his friend the Lascar, but this fault was soon remedied, and he was seized and searched, without anything being found which could incriminate him. There were, it is true, some blood-stains upon his right shirt-sleeve, but he pointed to his ring-finger, which had been cut near the nail, and explained that the bleeding came from there, adding that he had been to the window not long before, and that the stains which had been observed there came doubtless from the same source. He denied strenuously having ever seen Mr. Neville St. Clair and swore that the presence of the clothes in his room was as much a mystery to him as to the police. As to Mrs. St. Clair’s assertion that she had actually seen her husband at the window, he declared that she must have been either mad or dreaming. He was removed, loudly protesting, to the police-station, while the inspector remained upon the premises in the hope that the ebbing tide might afford some fresh clew.

“And it did, though they hardly found upon the mud-bank what they had feared to find. It was Neville St. Clair’s coat, and not Neville St. Clair, which lay uncovered as the tide receded. And what do you think they found in the pockets?”

“I cannot imagine.”

“No, I don’t think you would guess. Every pocket stuffed with pennies and half-pennies – 421 pennies and 270 half-pennies. It was no wonder that it had not been swept away by the tide. But a human body is a different matter. There is a fierce eddy between the wharf and the house. It seemed likely enough that the weighted coat had remained when the stripped body had been sucked away into the river.”

“But I understand that all the other clothes were found in the room. Would the body be dressed in a coat alone?”

“No, sir, but the facts might be met speciously enough. Suppose that this man Boone had thrust Neville St. Clair through the window, there is no human eye which could have seen the deed. What would he do then? It would of course instantly strike him that he must get rid of the tell-tale garments. He would seize the coat, then, and be in the act of throwing it out, when it would occur to him that it would swim and not sink. He has little time, for he has heard the scuffle downstairs when the wife tried to force her way up, and perhaps he has already heard from his Lascar confederate that the police are hurrying up the street. There is not an instant to be lost. He rushes to some secret hoard, where he has accumulated the fruits of his beggary, and he stuffs all the coins upon which he can lay his hands into the pockets to make sure of the coat’s sinking. He throws it out, and would have done the same with the other garments had not he heard the rush of steps below, and only just had time to close the window when the police appeared.”
