“The case is extraordinarily puzzling,” said Mr. Ludgrove sympathetically. “If you feel disposed to discuss it, Inspector, I suggest that you do so in comfort over at my place. I can make you a cup of cocoa, or, if you prefer it, I can supply you with something stronger. I always kept a bottle of whiskey in reserve for poor Mr. Copperdock.”

“Well, it’s very good of you, Mr. Ludgrove,” replied Whyland gratefully. “What’s the time? After two? I want to stay about here until it’s light. I’ll just tell Waters where I’m to be found in case he wants me. Then I shall be very glad to accept your kind hospitality.”
