The next morning, Poirot discovers Ratchett was murdered during the night after having been stabbed a dozen times. Poirot and Bouc investigate the other passengers as repairs begin. Evidence indicates that Ratchett was murdered by one person, and Caroline Hubbard, a fellow passenger, claims that a man had been in her compartment in the night. Poirot discovers a partially burned note connecting Ratchett to the kidnapping of Daisy Armstrong, a child who was abducted from her bedroom and held for ransom.
