"I shouldn't wonder if we're getting at something like a real clue," he said. "It seems evident that Ashton was not very particular about showing his diamond to people! If he'd show it--readily--to a lot of Hatton Garden diamond merchants, who, after all, were strangers to him, how do we know that he wouldn't show it to other men? The fact is, wealthy men like that are often very careless about their possessions. Possibly a diamond worth fifty or sixty thousand pounds wasn't of so much importance in Ashton's eyes as it would have been in--well, in mine. And how do we know that he didn't show the diamond to the man with the muffler, in Paris, and that the fellow followed him here and murdered him for it?" "Possible!" said Armitstead. "Doesn't it strike you as strange, though," suggested Viner, "that the first news of this diamond comes from Van Hoeren? One would have thought that Ashton would have mentioned it--and shown it--to Miss Wickham and Mrs. Killenhall. Yet apparently--he never did." "Yes, that does seem odd," asserted Mr. Pawle. "But there seems to be no end of oddity in this case. And there's one thing that must be done at once: we must have a full and thorough search and examination of all Ashton's effects. His house must be thoroughly searched for papers and so on. Viner, I suppose you're going home? Do me the favour to call at Miss Wickham's, and tell her that I propose to come there at ten o'clock tomorrow morning, to go through Ashton's desk and his various belongings with her--surely there must be something discoverable that will throw more light on the matter. And in the meantime, Viner, don't say anything to her about our journey to Marketstoke--leave that for a while." Viner went away from Crawle, Pawle, and Rattenbury's in company with Armitstead. Outside, the Lancashire business man gave him a shrewd glance. "I very much doubt if that diamond has anything whatever to do with Ashton's murder," he said. "From what I saw of him, he seemed to me to be a very practical man, full of business aptitude and common sense, and I don't believe that he'd make a practice of walking about London with a diamond of that value in his pocket. It's all very well that he should have it in his pocket when he went down to Hatton Garden--he had a purpose. But that he should always carry it--no, I don't credit that, Mr. Viner." "I can scarcely credit such a foolish thing myself," said Viner. "But--where is the diamond?" "Perhaps you'll find it tomorrow," suggested Armitstead. "The man would be sure to have some place in his house where he kept his valuables. I shall be curious to hear." "Are you staying in town?" inquired Viner. "I shall be at the Hotel Cecil for a fortnight at least," answered Armitstead. "And if I can be of any use to you or Mr. Pawle, you've only to ring me up there. You've no doubt yourself, I think, that the unfortunate fellow Hyde is innocent?"
