Meanwhile I had been looking about the room for a box or a case where the cipher messages might be hid. I saw nothing of the kind. Of course they might be hidden between the pages of a book. I went from table to table, taking them by the boards and shaking the leaves. Not a scrap of paper tumbled out. There was another door in the room besides that which led on to the landing.

"Mademoiselle, what room is that?" I asked.

"My bedroom," she answered simply, and with a gesture full of dignity she threw open the door.

I carried the mud and snow and the grime of a camp without a scruple of remorse into that neat and pretty chamber. Mademoiselle Sophie followed me as I searched wardrobe and drawer and box. At last I came to one drawer in her dressing-table which was locked. I looked suddenly at the young lady. She was watching me out of the corners of her eyes with a peculiar intentness.

"Open that drawer, mademoiselle," I said.

"It contains only some private things."

"Open that drawer or I burst it open."

"No," she cried, as I jerked the handle. "I will open it."
