Le couteau sur la nuque

Lord Edgware Dies is a work of detective fiction by British writer Agatha Christie, published in the UK by the Collins Crime Club in September 1933 and in the US by Dodd, Mead and Company later in the same year under the title of Thirteen at Dinner. Before its book publication, the novel was serialised in six issues (March–August 1933) of The American Magazine as 13 For Dinner. The novel features Hercule Poirot, Arthur Hastings and Chief Inspector Japp. An American actress married to Lord Edgware asks Poirot to aid her in getting a divorce from her husband. Poirot agrees to help her, meeting her husband. That evening, the actress is seen at a dinner with thirteen guests, which has an associated superstition. By the next morning Lord Edgware and another American actress are found murdered, each at their own homes. Poirot investigates. The novel was well received at publication, in both London and New York, noting the clue that came from the chance remark of a stranger, calling it ingenious. A later review called it clever and unusual.
