"I was afraid of to-night. Perhaps for the time being I have lost my grip
a little on account of my nervous condition. I have had a long talk with
Dr. Bates, and he tried to persuade me to give up the idea of spending a
night here alone. He was rather doubtful about a supernatural solution to
the mystery. Then I didn't like the agent when I went to him to arrange
about the key. I shouldn't have entered the house with him to-night had I
not known you were here."

"Anything else?" I asked.

"Always that strong presentiment of danger," he answered. "Were these
hangings on the bed last night?"

"It was exactly as you see it now."

"The agent said the mattress and blankets had been put here for my
convenience."

"Did he say when they were put here?"

"I thought he meant to-day," said Quarles.

"No one has entered the house to-day," I answered.

"Yet, if Greaves was murdered, some one must have gained access to this
room somehow, in spite of the locked door and fastened window."

"You have dropped the idea of the supernatural, then?"
