“What’s this, Dawson!” he cried. “No gossiping! Go about your business! And you, what the devil do you want here?”

“I’ve no time to talk to every gadabout. We want no stranger here. Be off, or you may find a dog at your heels.”

Holmes leaned forward and whispered something in the trainer’s ear. He started violently and flushed to the temples.

“It’s a lie!” he shouted, “an infernal lie!”

“Very good. Shall we argue about it here in public or talk it over in your parlor?”
