The Hollow is a work of detective fiction by Agatha Christie and first published in the US by Dodd, Mead and Company in 1946 and in the UK by the Collins Crime Club in November of the same year. The US edition retailed at $2.50 and the UK edition at eight shillings and sixpence (8/6). A paperback edition in the US by Dell books in 1954 changed the title to Murder after Hours.
The novel is a fine example of a "country house mystery" and was the first of her novels in four years to feature Christie's Belgian detective Hercule Poirot—one of the longest gaps in the entire series. Christie, who often admitted that she did not like Poirot (a fact parodied by her recurring novelist character Ariadne Oliver), particularly disliked his appearance in this novel. His late arrival, jarring, given the established atmosphere, led her to claim in her Autobiography that she "ruined by the introduction of Poirot".
