"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. 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.
