"I'm not so particular," he returned laughingly, "but the silver in that hole was never touched, nor I dare say even imagined by mortal man before. However, there is something else about the hollow that I want to tell you. You remember the slipper that you picked up?"
"Yes."
"Well, I lied to you about that; I never dropped it. On the contrary, I had picked up the mate of it very near where you found yours, and I wanted to know to whom it belonged. For I don't mind telling you now, Collinson, that I believe there WAS a woman in that house, and the same woman whose face I saw at the window. You remember how the boys joked me about it—well, perhaps I didn't care that you should laugh at me too, but I've had a sore conscience over my lie, for I remembered that you seemed to have some interest in the matter too, and I thought that maybe I might have thrown you off the scent. It seemed to me that if you had any idea who it was, we might now talk the matter over and compare notes. I think you said—at least, I gathered the idea from a remark of yours," he added hastily, as he remembered that the suggestion was his own, and a satirical one—"that it reminded you of your wife's slipper. Of course, as your wife is dead, that would offer no clue, and can only be a chance resemblance, unless"— He stopped.
"Have you got 'em yet?"
"Yes, both." He took them from the pocket of his riding-jacket.
As Collinson received them, his face took upon itself an even graver expression. "It's mighty cur'ous," he said reflectively, "but looking at the two of 'em the likeness is more fetchin'. Ye see, my wife had a STRAIGHT foot, and never wore reg'lar rights and lefts like other women, but kinder changed about; ye see, these shoes is reg'lar rights and lefts, but never was worn as sich!"
"There may be other women as peculiar," suggested Key.
"There MUST be," said Collinson quietly.
For an instant Key was touched with the manly security of the reply, for, remembering Uncle Dick's scandal, it had occurred to him that the unknown tenant of the robbers' den might be Collinson's wife. He was glad to be relieved on that point, and went on more confidently:—
"So, you see, this woman was undoubtedly in that house on the night of the fire. She escaped, and in a mighty hurry too, for she had not time to change her slippers for shoes; she escaped on horseback, for that is how she lost them. Now what was she doing there with those rascals, for the face I saw looked as innocent as a saint's."
