"The fellow who devised that was a genius," he said, admiringly, pushing it back into place. "I wonder what its contents have been from the days of Madame de Montespan down to the present? Love letters, mostly, I suppose, since they are the things which need concealment most. Don't you wish this drawer could tell its secrets, Lester?"

"There is one I wish it would tell, if it knows it," I said. "I wish it would tell who killed Philip Vantine. I suppose you will agree with me that our pretty theory has got a knock-out blow, this time."

"It looks that way, doesn't it?"

"There is no poisoned mechanism about that drawer—that's sure," I added.

"No, and never has been," Godfrey agreed.

"And that leaves us all at sea, doesn't it? It leaves the whole affair more mysterious than ever. I can't understand it," and I sat down in my bewilderment and rubbed my head. I really felt for an instant as though I had gone mentally blind. "There is one thing sure," I added. "The killing, whatever its cause, was done out there in the ante-room, not in here."

"What makes you think that?"

"We believe that Drouet came here to get Vantine's permission to open this drawer and get the letters, no doubt representing himself as the agent of their owner."

"I think it's a pretty good guess," said Godfrey, pensively.

"Our theory was that, after being shown into the ante-room, he discovered the cabinet, tried to open the drawer, and was killed in the attempt. But it is evident enough now that there is nothing about that drawer to hurt any one."
