However, Lestrade was anxious to get his man into safe quarters, so within a few minutes our cab had been summoned and we were all four upon our way to London. Not a word would our captive say; but he glared at us from the shadow of his matted hair, and once, when my hand seemed within his reach, he snapped at it like a hungry wolf. We stayed long enough at the police-station to learn that a search of his clothing revealed nothing save a few shillings and a long sheath knife, the handle of which bore copious traces of recent blood. "That's all right," said Lestrade, as we parted. "Hill knows all these gentry, and he will give a name to him. You'll find that my theory of the Mafia will work out all right. But I'm sure I am exceedingly obliged to you, Mr. Holmes, for the workmanlike way in which you laid hands upon him. I don't quite understand it all yet." "I fear it is rather too late an hour for explanations," said Holmes. "Besides, there are one or two details which are not finished off, and it is one of those cases which are worth working out to the very end. If you will come round once more to my rooms at six o'clock to-morrow I think I shall be able to show you that even now you have not grasped the entire meaning of this business, which presents some features which make it absolutely original in the history of crime. If ever I permit you to chronicle any more of my little problems, Watson, I foresee that you will enliven your pages by an account of the singular adventure of the Napoleonic busts." * * * * * When we met again next evening Lestrade was furnished with much information concerning our prisoner. His name, it appeared, was Beppo, second name unknown. He was a well-known ne'er-do-well among the Italian colony. He had once been a skilful sculptor and had earned an honest living, but he had taken to evil courses and had twice already been in gaol--once for a petty theft and once, as we had already heard, for stabbing a fellow-countryman. He could talk English perfectly well. His reasons for destroying the busts were still unknown, and he refused to answer any questions upon the subject; but the police had discovered that these same busts might very well have been made by his own hands, since he was engaged in this class of work at the establishment of Gelder and Co. To all this information, much of which we already knew, Holmes listened with polite attention; but I, who knew him so well, could clearly see that his thoughts were elsewhere, and I detected a mixture of mingled uneasiness and expectation beneath that mask which he was wont to assume. At last he started in his chair and his eyes brightened. There had been a ring at the bell. A minute later we heard steps upon the stairs, and an elderly, red-faced man with grizzled side-whiskers was ushered in. In his right hand he carried an old-fashioned carpet-bag, which he placed upon the table. "Is Mr. Sherlock Holmes here?"
