Sherlock Holmes and I surveyed this curt announcement and the rueful face behind it, until the comical side of the affair so completely overtopped every other consideration that we both burst out into a roar of laughter.

“I cannot see that there is anything very funny,” cried our client, flushing up to the roots of his flaming head. “If you can do nothing better than laugh at me, I can go elsewhere.”

“No, no,” cried Holmes, shoving him back into the chair from which he had half risen. “I really wouldn’t miss your case for the world. It is most refreshingly unusual. But there is, if you will excuse my saying so, something just a little funny about it. Pray what steps did you take when you found the card upon the door?”
