“You had occasion to open the drawer?”

“It is really a very old bureau and none of the drawers fit closely. Dust lies on the ledges and you always have to open them a little to dust properly. They were never kept locked.”

“Possibly your father had taken the revolver with him.”

“No. I had seen it there after he had gone. He rode to Stinbridge immediately after lunch and did not return until nearly eight. After he left I went to dust his room. It was then that I saw it. I was doing the desk when Frank knocked and interrupted me. That is how I came to be there twice.”

“But you said that you had no proof, Miss Whitmarsh,” Carrados reminded her, with deep seriousness. “Do you not recognize the importance—the deadly importance—that this one shred of evidence may assume?”

“Does it?” she replied simply. “I am afraid that I am rather dull just now. All yesterday I was absolutely dazed; I could not do the most ordinary things. I found myself looking at the clock for minutes together, yet absolutely incapable of grasping what time it was. In the same way I know that it struck me as being funny about the revolver but I always had to give it up. It was as though everything was there but things would not fit in.”

“You are sure, absolutely sure, that you saw the revolver there after your father had left, and missed it before he returned?”

“Oh yes,” said the girl quickly; “I remember realizing how curious it was at the time. Besides there is something else. I so often had things to ask papa about when he was out of the house that I got into the way of making little notes to remind me later. This morning I found on my dressing-table one that I had written on Thursday afternoon.”

“About this weapon?”

“Yes; to ask him what could have become of it.”
