The 4:50 From Paddington // What Mrs. McGillicuddy Saw — Agatha Christie

SHE WAS THE ONLY WITNESS TO A MURDER!

Standing with his back to her was a man. His hands were around a woman's throat. He was slowly, relentlessly strangling her. As Mrs. McGillicuddy watched, fascinated, the end came. The body went limp and crumpled in the man's hands.

Nobody believed Mrs. McGillicuddy...because there was no corpse.

Nobody, that is, except Miss Jane Marple, who figured out where the body was hidden--and then showed Scotland Yard how to trap the killer!
