"Not always; but usually it is, or course; even if they are not together, they certainly _have_ been at one time, and to have one is a very long step toward having the other. Now, to begin with, is anybody suspected?" "Well, the police are reserved, but I believe the fact is they've nothing to say. Claridge won't admit that he suspects any one, though he believes that whoever it was must have watched him yesterday evening through the back window of his room, and must have seen him put the cameo away in his desk; because the thief would seem to have gone straight to the place. But I half fancy that, in his inner mind, he is inclined to suspect one of two people. You see, a robbery of this sort is different from others. That cameo would never be stolen, I imagine, with the view of its being sold--it is much too famous a thing; a man might as well walk about offering to sell the Tower of London. There are only a very few people who buy such things, and every one of them knows all about it. No dealer would touch it; he could never even show it, much less sell it, without being called to account. So that it really seems more likely that it has been taken by somebody who wishes to keep it for mere love of the thing--a collector, in fact--who would then have to keep it secretly at home, and never let a soul besides himself see it, living in the consciousness that at his death it must be found and this theft known; unless, indeed, an ordinary vulgar burglar has taken it without knowing its value." "That isn't likely," Hewitt replied. "An ordinary burglar, ignorant of its value, wouldn't have gone straight to the cameo and have taken it in preference to many other things of more apparent worth, which must be lying near in such a place as Claridge's." "True--I suppose he wouldn't. Although the police seem to think that the breaking in is clearly the work of a regular criminal--from the jimmy-marks, you know, and so on." "Well, but what of the two people you think Mr. Claridge suspects?" "Of course I can't say that he does suspect them--I only fancied from his tone that it might be possible; he himself insists that he can't, in justice, suspect anybody. One of these men is Hahn, the traveling agent who sold him the cameo. This man's character does not appear to be absolutely irreproachable; no dealer trusts him very far. Of course Claridge doesn't say what he paid him for the cameo; these dealers are very reticent about their profits, which I believe are as often something like five hundred per cent as not. But it seems Hahn bargained to have something extra, depending on the amount Claridge could sell the carving for. According to the appointment he should have turned up this morning, but he hasn't been seen, and nobody seems to know exactly where he is." "Yes; and the other person?"
