4.50 from Paddington

Two trains come close together for a brief moment, and during that time, Elspeth McGillicuddy believes she saw a man murder a woman by strangling her. It was only a quick glance through a train window as they passed each other. Since she is the sole witness and there is no body or suspects, only her friend Jane Marple would believe her. Miss Marple should never be underestimated, as all crime writers acknowledge their debt to Agatha Christie and her work is never dull, as stated by The Times.
