Nemesis is a work of detective fiction by Agatha Christie (1890–1976) and first published in the UK by the Collins Crime Club in November 1971 and in the US by Dodd, Mead and Company later in the same year. The UK edition retailed at £1.50 and the US edition at $6.95. It was the last Miss Marple novel the author wrote, although Sleeping Murder was the last Miss Marple novel to be published. Miss Marple first encounters Jason Rafiel in A Caribbean Mystery, where they solve a mystery. Miss Marple receives communications from him, sent posthumously, setting up the plot of this novel.
