"Quite so; still the lady is decidedly attractive, and Murray Wigan is a man. The man who holds himself barred from admiring one woman just because he happens to be engaged to another is not a very conspicuous biped. I am not reproaching you, I should probably do the same myself, but Zena will take you to task no doubt, and you will explain and promise not to do it any more, and—"
"I haven't done anything which requires explanation," I said irritably.
"Of course not, but that may not be Zena's view, and I daresay Mrs. Selborne believes you are more than half in love with her. I happened to overhear part of your conversation. She was putting your admiration to the test, rather a severe test, by the way, since you are an invalid. Probably she is smiling to herself in the glass as she dresses for dinner, which reminds me you have none too much time to dress, and you must not be late to-night."
"Why not? I am feeling quite fit again. If there is anything to be done I am quite capable of doing it."
"Dress, Wigan, while I talk. Since you broke down at a crucial point I have been helping Percival. I daresay he will get the kudos in this case, but you mustn't grudge him that."
"I don't."
"We have progressed," Quarles went on. "I will give you my line of argument and the result so far. We start with Squires. He led us into a trap, but the gang with which he was formerly connected has practically ceased to exist. His old companions have seen nothing of him; he is supposed to have turned good, and I find he has been a member of that hooligan club for over a year with an irreproachable record during that time. Two conclusions seem to arise; either Squires is connected with another gang, or some compulsion was put upon him to betray us. I incline to the second idea, and if I am correct there must have been a strong incentive to persuade Squires to do what he did. Perhaps he wished to protect some one."
"What did Percival say to that?" I asked as I put the links into my shirt.
"He jeered at it, of course, as you are inclined to do; indeed, it was quite a long time before Percival awoke to the fact that I was not quite a fool. Now the machinery of Scotland Yard seems to have proved that these robberies are not the work of a known gang; we may therefore assume that persons unknown to the police are at work. The methods adopted are clever. The property is stolen, yet no one has disappeared from the hotel, neither guest nor servant, and in no case has any of the property been found in the possession of any one in the hotel. Shall we suppose that it has been carefully lowered from a bedroom window to an accomplice without? None of this property has been traced, which leads us to two hypotheses; either it has been got out of the country and disposed of abroad, or the thieves can afford to bide their time. When you consider the worth of the jewels stolen, it seems remarkable that nothing should have been traced in the known markets abroad, and I am inclined to think the thieves can afford to wait. Having arrived at this point—"
"Without a scrap of evidence," I put in.
