The A.B.C. Murders

The A.B.C. Murders is a detective novel by Agatha Christie, first published in 1936. It belongs to the Hercule Poirot canon and follows a series of killings linked by the signature of an unknown murderer called A.B.C. Rather than relying on spectacle, the book is built around investigation, patterns, and the slow piecing together of clues, with the case unfolding through several perspectives.

It suits readers who like classic crime fiction, a structured puzzle, and familiar figures from the Poirot world, including Hercule Poirot, Arthur Hastings, and Chief Inspector Japp. One of its notable features is the way it mixes first person and third person narration, which gives the mystery an unusual shape and keeps information arriving from different angles. If you enjoy detective stories where the method of telling matters as much as the case itself, this is a good fit.
