“Oh,” said the Inspector. “Well, I suppose that is quite natural, but I shall probably have a lot more questions to ask you later.”
“Quite,” muttered Harley, “quite. Come on, Knox. Good-night, Inspector Aylesbury.”
“Good-night.”
Harley walked out of the dining room and across the deserted hall. He slowly mounted the stairs and I followed him into his room. It was now quite light, and as my friend dropped down upon the bed I thought that he looked very tired and haggard.
“Knox,” he said, “shut the door.”
I closed the door and turned to him.
“You heard that question about Miss Beverley?” I began.
“I heard it, and I am wondering what her answer will be when the Inspector puts it to her personally.”
“Surely it is obvious?” I cried. “A cloud of apprehension had settled on the house last night, Harley, which was like the darkness of Egypt. The poor girl was afraid to go to bed. She was probably sitting up reading.”
“Hm,” said Harley, drumming his feet upon the carpet. “Of course you realize that there is one person in Cray’s Folly who holds the clue to the heart of the mystery?”
