The story begins when a friend of Dr. Watson's wife comes to Watson's house, frantic because her husband, who is addicted to opium, has gone missing. Watson helps her pull him out of the opium den and sends him home. Watson is surprised to find that Sherlock Holmes is there too, in disguise and trying to get information to solve a different case about a man who has disappeared. Watson stays to listen to Holmes tell the story of the case of Neville St. Clair.
St. Clair is a prosperous, respectable, punctual man. His family's home is in the country, but he visits London every day on business. One day when Mr. St. Clair was in London, Mrs. St. Clair also went to London separately. She happened to pass down Upper Swandam Lane, a "vile alley" near the London docks, where the opium den is. Glancing up, she saw her husband at a second-floor window of the opium den. He vanished from the window immediately, and Mrs. St. Clair was sure that there was something wrong.
She tried to enter the building; but her way was blocked by the opium den's owner, a lascar. She fetched the police, but they did not find Mr. St. Clair. The room behind the window was the lair of a dirty, disfigured beggar, known to the police as Hugh Boone. The police were about to put her story down as a mistake of some kind when Mrs. St. Clair noticed a box of wooden toy bricks that her husband said he would buy for their son. A further search turned up some of St. Clair's clothes. Later, his coat, with the pockets stuffed with hundreds of pennies and halfpennies, was found on the bank of the River Thames, just below the building's back window.
Hugh Boone was arrested at once, but would say nothing, except to deny any knowledge of St. Clair. He also resisted any attempt to make him wash. Holmes was initially quite convinced that St. 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.
