Incredulously, I thought of my acquaintance of the Lavender Arms, with his bemused expression and his magnificent brow; and a great doubt and wonder grew up in my mind.
I became increasingly impatient for the return of Paul Harley. I felt that a clue of the first importance had fallen into my possession; so that when, presently, as I walked impatiently up and down the room, the door opened and Harley entered, I greeted him excitedly.
“Harley!” I cried, “Harley! I have learned a most extraordinary thing!”
Even as I spoke and looked into the keen, eager face, the expression in Harley’s eyes struck me. I recognized that in him, too, intense excitement was pent up. Furthermore, he was in one of his irritable moods. But, full of my own discoveries:
“I chanced to glance at this book,” I continued, “whilst I was waiting for you. You have underlined certain passages.”
He stared at me queerly.
“I discovered the book in my own library after you had gone last night, Knox, and it was then that I marked the passages which struck me as significant.”
“But, Harley,” I cried, “the man who is quoted here, Colin Camber, lives in this very neighbourhood!”
“I know.”
“What! You know?”
“I learned it from Inspector Aylesbury of the County Police half an hour ago.”
Harley frowned perplexedly. “Then, why, in Heaven’s name didn’t you tell me?” he exclaimed. “It would have saved me a most disagreeable journey into Market Hilton.”
