"I'm perplexed, Wigan," the professor went on. "I'm a man in a wood and can't find my way out. That is literal rather than a figure of speech. In my endeavor to get out and look for a murderer I seem to keep on hurting myself against the trunks and branches of trees, and out of the darkness about me wild animals seem to roar with laughter at my idea of murder.

"Why did you call upon her?"
"To ask why she went to see Mr. Seligmann, of Hampstead, on Saturday night."
"Did she go there?"
