4.50 from Paddington

A woman glimpses a horrifying crime through a train window—a man strangling a woman—but in seconds, both trains pass and she is left with only her memory and no body to prove it happened. When Elspeth McGillicuddy confides in her friend Miss Marple, the sharp-minded detective takes her account seriously, despite the skepticism of everyone else. With no suspects, no corpse, and only a fleeting moment of truth, Marple must unravel a puzzle that exists largely in what others refuse to see. Agatha Christie crafts a masterpiece of deduction where the smallest details unlock the darkest secrets.
