Poirot Refuses Ratchett's Case

In the dining car, Poirot observes the other passengers: Princess Dragomiroff, the Hungarian couple, Mrs. Hubbard, Greta Ohlsson, and others. After lunch, Ratchett approaches Poirot and offers him a large sum of money to protect him from an enemy who has threatened his life. Poirot refuses bluntly, stating he does not like Ratchett's face. This refusal establishes Ratchett's vulnerability and Poirot's moral stance.
