Murder on the Orient Express

Summary

Railway director and fellow Belgian Monsieur Bouc secures Poirot a last minute berth on the Orient Express, returning to England from Istanbul. Ratchett, an abrasive American businessman, traveling with his valet and male secretary, tries to secure Poirot's services as he fears that his life is in danger. Poirot turns him down, but the next morning, whilst the train is stuck in a snowdrift in Croatia, Ratchett is found stabbed to death.
