The Man With the Twisted Lip

Neville St. Clair, a respectable businessman, has disappeared and his wife claims she saw him at the upper window of an opium den. Rushing upstairs to the room she found only a beggar who denied any knowledge of St. Clair—whose clothes are later found in the room, and his coat, laden with coins, in the River Thames outside the window. The beggar is arrested, but a few days later St. Clair's wife receives a letter from her husband. Holmes concludes, then proves, that the beggar is actually St. Clair in disguise; he confesses that he has been leading a double life as a beggar, making more money that way than in his nominal work.
