Clair had been murdered, and that Boone was involved. Thus he investigated the den in disguise. He and Watson return to St. Clair's home, to a surprise. It is several days after the disappearance; but on that day Mrs. St. Clair had received a letter from her husband in his own handwriting, with his wedding ring enclosed, telling her not to worry. This forces Holmes to reconsider his conclusions, leading him eventually to an extraordinary solution. Holmes and Watson go the police station where Hugh Boone is held; Holmes brings a bath sponge in a Gladstone bag. Finding Boone asleep, Holmes washes the sleeping Boone's dirty face—revealing Neville St. Clair. Mr. St. Clair has been leading a double life, as a respectable businessman, and as a beggar. In his youth, he had been an actor before becoming a newspaper reporter. In order to research an article, he had disguised himself as a beggar for a short time, and was able to collect a surprising amount of money due to a skillset uncommon to beggars; his actor's skills enabled him to emulate a more sympathetic character with make-up, as well as provide a repertoire of witty dialogue with which to entertain passers-by to offer coins—he was as much a street performer as a beggar. Later, he was saddled with a large debt, and returned to the street to beg for several days to pay it off. His newspaper salary was meagre and, tempted by the much larger returns of begging, he eventually became a "professional" beggar. His takings were large enough that he was able to establish himself as a country gentleman, marry well, and begin a respectable family. His wife and children never knew what he did for a living, and when arrested, he feared exposure more than prison or the gallows. But there is no murder, so he is released, and Holmes and the police agree to keep Mr. St. Clair's secret as long as no more is heard of Hugh Boone. Points of interest The ability of St. Clair to earn a good living begging is considered by some to be an unlikely event, but others disagree. Doyle may have got the idea of a professional man making his money from begging from a short story by William Makepeace Thackeray called "Miss Shum's Husband" (1838). The morning the mystery is solved Watson awakes about 4:25 a.m., yet the
