I had not, as a matter of fact, given the matter a moment's consideration.

"We are going to call on Mr. Jellicoe," Thorndyke explained. "There is something behind this affair, and until I have ascertained what it is, the case is not complete from my point of view."

"Wouldn't it have done as well to-morrow?" I asked.

"It might; and then it might not. There is an old saying as to catching a weasel asleep. Mr. Jellicoe is a somewhat wide-awake person, and I think it best to introduce him to Inspector Badger at the earliest possible moment."

"The meeting of a weasel and a badger suggests a sporting interview," remarked Jervis. "But you don't expect Jellicoe to give himself away, do you?"

"He can hardly do that, seeing that there is nothing to give away. But I think he may make a statement. There were some exceptional circumstances, I feel sure."

"How long have you known that the body was in the Museum?" I asked.

"About thirty or forty seconds longer than you have, I should say."

"Do you mean," I exclaimed, "that you did not know until the negative was developed?"

"My dear fellow," he replied, "do you suppose that, if I had had certain knowledge where the body was, I should have allowed that noble girl to go on dragging out a lingering agony of suspense that I could have cut short in a moment? Or that I should have made these humbugging pretenses of scientific experiments if a more dignified course had been open to me?"
