The Clocks is a work of detective fiction by British writer Agatha Christie, first published in the UK by the Collins Crime Club on 7 November 1963 and in the US by Dodd, Mead and Company the following year. It features the Belgian detective Hercule Poirot. The UK edition retailed at sixteen shillings (16/-) and the US edition at $4.50. In the novel Poirot never visits any of the crime scenes or speaks to any of the witnesses or suspects. He is challenged to prove his claim that a crime can be solved by the exercise of the intellect alone. The novel marks the return of partial first-person narrative, a technique that Christie had largely abandoned earlier in the Poirot sequence but which she had employed in the previous Ariadne Oliver novel, The Pale Horse (1961). There are two interwoven plots: the mystery Poirot works on from his armchair while the police work on the spot, and a Cold War spy story told in the first person narrative. Reviews at the time of publication found the writing up to Christie's par, but found negatives: the murder of a character about to add useful information was considered "corny" and "unworthy" of the author, and "not as zestful". In contrast, Barnard's review in 1990 said it was a "lively, well-narrated, highly unlikely late specimen" of Christie's writing. He loved the clocks at the start, and was oddly disappointed that they were red herrings. Source: Wikipedia (en)
