Play The Mysterious Affair at Styles — an interactive story where YOU are the hero

after the classic by Agatha Christie, 1920

A poisoning at an English country house, a locked dispatch-case, and a dozen tidy alibis. Match your little grey cells against Hercule Poirot's — or play Poirot himself — and arrange the trap that makes the real murderer betray the perfect crime.

A moment from one playthrough

The extra coffee cup is missing, the fire was lit on a warm July night, and the torn will is ash in the grate — three small wrongnesses that don't fit anyone's story. Poirot taps his egg-shaped head and waits for you. Name the fireplace as the key clue, or press the alibi that depends on that missing cup?
