"Take these people in their order. Mr. Claridge is out of the question, as a dealer with a reputation to keep up would be, even if he hadn't immediately sent you this five thousand pounds--more than the market value, I understand, of the cameo. The assistant is a reputable man, against whom nothing is known, who would never need to break in, and who must understand his business well enough to know that he could never attempt to sell the missing stone without instant detection. Hahn is a man of shady antecedents, probably clever enough to know as well as anybody how to dispose of such plunder--if it be possible to dispose of it at all; also, Hahn hasn't been to Claridge's to-day, although he had an appointment to take money. Lastly, Mr. Woollett is a gentleman of the most honorable record, but a perfectly rabid collector, who had made every effort to secure the cameo before you bought it; who, moreover, could have seen Mr. Claridge working in his back room, and who has perfectly easy access to Mr. Claridge's roof. If we find it can't be none of these, then we must look where circumstances indicate." There was unwonted excitement at Mr. Claridge's place when Hewitt and his client arrived. It was a dull old building, and in the windows there was never more show than an odd blue china vase or two, or, mayhap, a few old silver shoe-buckles and a curious small sword. Nine men out of ten would have passed it without a glance; but the tenth at least would probably know it for a place famous through the world for the number and value of the old and curious objects of art that had passed through it. On this day two or three loiterers, having heard of the robbery, extracted what gratification they might from staring at nothing between the railings guarding the windows. Within, Mr. Claridge, a brisk, stout, little old man, was talking earnestly to a burly police-inspector in uniform, and Mr. Cutler, who had seized the opportunity to attempt amateur detective work on his own account, was groveling perseveringly about the floor, among old porcelain and loose pieces of armor, in the futile hope of finding any clue that the thieves might have considerately dropped. Mr. Claridge came forward eagerly. "The leather case has been found, I am pleased to be able to tell you, Lord Stanway, since you left." "Empty, of course?" "Unfortunately, yes. It had evidently been thrown away by the thief behind a chimney-stack a roof or two away, where the police have found it. But it is a clue, of course." "Ah, then this gentleman will give me his opinion of it," Lord Stanway said, turning to Hewitt. "This, Mr. Claridge, is Mr. Martin Hewitt, who has been kind enough to come with me here at a moment's notice. With the police on the one hand and Mr. Hewitt on the other we shall certainly recover that cameo, if it is to be recovered, I think."
