Task: Question Generation
Input (English): Passage: While travelling by train with his sidekick and assistant, "Goldie" Locke, for a vacation in San Francisco, Tom Lawrence, a.k.a. The Falcon, meets Annie Marshall, a lonely little girl. Annie tells them that she is being held prisoner by her nurse, Miss Carla Keyes, and butler Loomis.  Annie's story is cut short when Miss Keyes comes for her. Shortly after, the little girl rushes back to Tom to tell him her nurse is dead.
Tom and Goldie take charge of Annie but police are notified that the little girl was kidnapped. When the train arrives in San Francisco, the police are waiting for the Falcon. Released on $10,000 bail, posted by Doreen Temple, who promises Tom she will disclose the motive behind her generosity. At dinner that evening, Doreen brings along her bodyguard Rickey, posing as a police officer. When they leave, Rickey knocks Tom out and takes him to Doreen's apartment where she interrogates him about the murder, and to stay away from gangster Peter Vantine and the cargo ship, the S.S. Citadel.
After Tom returns to his hotel to collect Goldie, they decide to pay a visit to Annie's house, where they meet her older sister Joan who denies that she knows Doreen or Vantine. Annie claims she made up the story about being held captive, but when Tom sneaks back to the house to talk to her, she says Loomis is holding her prisoner. She takes them to Carla's room where they find a photograph of a ship's officer, signed to his wife, Carla.
Loomis hears someone rummaging around in the nurse's room, but is shot dead by an unknown assailant. Returning to their hotel, Tom is confronted by Vantine, who is brandishing a gun. When Tom disarms him, he learns Doreen was the romantic interest of an ex-bootlegger, Duke Monette, involved with a shipment aboard the S.S. Citadel.
Output (English): What location does Doreen tell Tom to stay away from?
