Mysterious affair at Styles: A refugee of the Great War, Poirot has settled in England near Styles Court, the country estate of his wealthy benefactor, the elderly Emily Inglethorp. When Emily is poisoned and the authorities are baffled, Poirot puts his prodigious sleuthing skills to work. Suspects are plentiful, including the victim’s much younger husband, her resentful stepsons, her longtime hired companion, a young family friend working as a nurse, and a London specialist on poisons who just happens to be visiting the nearby village.

Poirot investigates: First there was the mystery of the film star and the diamond... then came the “suicide” that was murder... the mystery of the absurdly cheap flat...a suspicious death in a locked gun room... a million dollar bond robbery... the curse of a pharaoh’s tomb... a jewel robbery by the sea... the abduction of a prime minister... the disappearance of a banker... a phone call from a dying man... and, finally, the mystery of the missing will.
