I thought William Tyrwhitt mad.
"I will come, by all means," he said.
The stranger bowed us out of the room.
"That is right," he exclaimed. "You will find me here. Good-bye for the present."
As we plunged like dazed men into the street, now grown sunny, I turned on my friend.
"William," I said, "did you happen to look back as we left the cabin?"
"No."
"I did."
"Well?"
"There was no stranger there at all. The place was empty."
