Hallowe'en Party

Hallowe'en Party is a mystery novel by English writer Agatha Christie, first published in the United Kingdom by the Collins Crime Club in November 1969 and in the United States by Dodd, Mead and Company later in the same year. This book was dedicated to writer P. G. Wodehouse. It has been adapted for television, radio, and most recently for the film A Haunting in Venice (2023). The novel features Belgian detective Hercule Poirot and the mystery novelist Ariadne Oliver. A boastful girl at a Hallowe'en party tells Mrs Oliver she once witnessed a murder; the same girl is later drowned in an apple-bobbing bucket, and Poirot must solve a two-pronged mystery: who killed the girl, and what, if anything, did she witness?
