"By whom?"

"I can't say. If I knew that I'd know who stole the body. But he was drugged by means of a perfume which is the same as that impregnating the devil-stick."

"How do you know?"

Jen was about to explain when he remembered the necessity of keeping silent concerning the visit of Isabella to the house.

"I can't tell you that just now," he said, in a hesitating manner. "But I know it for certain."

"Well," said Lady Meg, "it would seem that the devil-stick is the center of this mystery."

"I fancy it is."

"If you found the devil-stick you would know the truth?"

"I don't go so far as that," protested Jen. "If we found the person who stole the devil-stick from my smoking-room I might guess the truth."

"In that case, major, look at this," said Lady Meg, and produced an article from her pocket, an article which she held up triumphantly before the astonished eyes of the old man.
