To Sherlock Holmes, the big financial tycoon Neil Gibson, nicknamed the Golden King, is asking for help. Gibson’s wife was found in a park at the entrance to the Torsky Bridge, dressed for dinner, with a shot through the flight head. Near the corpse, no weapons were found. Suspicion fell on governess Gibson’s children, Miss Dunber. A revolver was found in her closet, the caliber of which corresponded to the caliber of the bullet, and a note was found from the governess from the governess with a proposal to meet. At the time of the murder, the governess was near the bridge. Everything is complicated by the fact that Gibson is in love with a girl.
Before the arrival of Gibson Holmes visits his manager. He warns the great detective that his master is a rude and unbalanced man. Mrs. Gibson was a Brazilian and madly loved him, but when her beauty withered, her husband’s attachment also disappeared. The manager asks Holmes not to judge Gibson in appearance.
admits that he married for love, eventually love passed, but his wife still loved him. Then a governess appeared, Miss Dunbar. Confessing her love, the Golden King put the girl in a difficult situation: she could not leave, because her family had relatives. Then Gibson vowed that he would leave her alone.
Gibson suggests that his wife was mad with jealousy and decided to kill her rival. During the fight, she accidentally shot herself, but Miss Dunbar rejects this version.
The great detective arrives at the crime scene. There he is met by a police sergeant. He says that the revolver lying in the closet of Miss Dunbar belongs to Mr. Gibson. He has a lot of weapons, but there are two such revolvers. The second can not find. The shot was fired at close range, no traces of the fight were found, and in the fist of the murdered they found a note from Miss Dunbar, in which it was reported that the girl would arrive at the appointed time at Torsky Bridge. The fact that the note was squeezed in a fist, Sherlock Holmes seems strange. Looking at the bridge, he notices on the parapet a schebin, a trail from the impact.
great detective weighs the facts: Gibson quarreled with his wife and insulted her at all, but at the time of the murder he was at home. Miss Dunbar admits that she has made an appointment, she can not say anything more, she was banned by a lawyer. But why did she put the revolver in her closet, instead of throwing it in the pond? Miss Dunber herself says she does not know about any revolver.
Sherlock Holmes visits the prison in Miss Dunbar. The girl says that Mrs. Gibson was furiously hating her. That morning Miss Dunbar received a note from the landlady, in which she asked to meet on the bridge, and destroy the note herself. At the request of Mrs. Gibson, the girl left the answer on the sundial. When Miss Dunbar came to the meeting, Mrs. Gibson threw all her hatred at her. Catching up her ears, so as not to hear curses in her address, Miss Dunbar escaped. She does not know anything about the revolver in the closet, since it was not in the morning.
During his reflections on the great detective he heard, he gets a guess, he jumps up and rushes to the scene of the crime.
Arriving at the scene of the crime, Holmes binds a solid stone and a revolver with string. Throwing a stone across the bridge parapet, he takes a weapon in his hand and unclasps it. The revolver falls into the water, bumping against the parapet and leaving a scrape on it. Holmes orders the sergeant to get weapons out of the water and says that next to it lie the sinker and the revolver, from which Mrs. Gibson shot herself, accusing the crime of an innocent man. Before committing suicide, she put a second revolver in the wardrobe of the girl.
