“Was it actually a hook-nose? I mean, had it a drooping tip?”

“Yes, the tip projected downwards and it was rather sharp—not bulbous.”

“And the chin? Should you call it a pronounced or a retreating chin?”

“Oh, it was quite a projecting chin, rather of the Wellington type.”

“Well,” he rejoined, with a smile, “I wouldn’t recall that unpleasant vision too often, if I were you. And now, may I, without disturbing you further, just take a look round the premises?”

“But, of course, Dr. Thorndyke,” she replied. “Do exactly what you please.”
