Task: Question Answering
Input (English): In London, Vivian Vedder (Renee Godfrey) verifies that a carpenter has completed a coffin for her recently deceased mother's body, which she is transporting to Scotland by train. She boards the train that evening, as do Lady Margaret Carstairs (Mary Forbes), who owns and is transporting the famous Star of Rhodesia diamond; Lady Margaret's son Roland (Geoffrey Steele); Holmes, whom Roland has hired to protect the diamond; Inspector Lestrade (Dennis Hoey), who is also worried about the diamond's safety; and Watson and his friend Major Duncan-Bleek (Alan Mowbray). Holmes briefly examines the diamond.Shortly afterward, Roland is murdered and the diamond is stolen. Lestrade, Holmes, and Watson learn nothing conclusive in questioning the other passengers, and Holmes is pushed out of the train, nearly to his death, but he climbs back inside and discovers a secret compartment in the coffin carrying Miss Vedder's mother. He suspects that one of the people on the train is the notorious jewel thief Colonel Sebastian Moran.Upon further questioning, Miss Vedder admits that a man paid her to transport the coffin. As Watson and Duncan-Bleek join the group, Holmes reveals that he swapped the diamond with an imitation while examining it. Lestrade takes possession of the real diamond.In the luggage compartment, Holmes and Watson find a train guard murdered with a poisoned dart. Meanwhile, a street criminal named Sands (Skelton Knaggs) incapacitates the conductor. Sands was hidden inside the coffin, and is in cahoots with Duncan-Bleek, who is in fact Colonel Moran. Sands and Moran go to Lestrade's room, where Sands knocks him unconscious and steals the diamond from him, but Moran double-crosses Sands, shooting him dead with the same dart gun he used to kill Roland and the guard.The train makes an unexpected stop to pick up several Scottish policemen led by Inspector McDonald (Boyd Davis). Holmes informs McDonald that Duncan-Bleek is really Moran, and McDonald arrests Moran and finds the diamond in his vest, but Moran seizes a policeman's gun and pulls the emergency cord to stop the train. During a scuffle in which the lights are turned off, Holmes subdues and handcuffs Moran, then secretly hides him under a table. When the lights are turned on again, the officers leave the train with Lestrade, his coat covering his face, believing he is Moran. As the train departs, Lestrade captures the thieves in the train station, and Holmes reveals to Watson and Moran that he recognized McDonald as an impostor and recovered the diamond from him during the fight., Question: Where does Moran have the diamond?
