Blurb

Postern of Fate is a work of detective fiction by Agatha Christie that was first published in the UK by the Collins Crime Club in October 1973 and in the US by Dodd, Mead and Company later in the same year. The UK edition retailed at £2.00 and the US edition at $6.95.
The book features her detectives Tommy and Tuppence Beresford and is the detectives' last appearance. It is the last novel Christie wrote, but not the last to be published as it was followed by two previously unpublished novels from the 1940s.
