No, the ABC Murders are not based on a true story. They are a work of fiction by the renowned author Agatha Christie, featuring her famous detective, Hercule Poirot. The novel, published in 1936, tells the tale of a serial killer who uses the alphabet as a guide to select his victims, leaving clues for Poirot to decipher.
While the events and characters in the book are entirely fictional, Agatha Christie drew inspiration from various real-life experiences and societal issues of her time. Although certain aspects of the murder mystery genre may resonate with real-world criminal cases, the ABC Murders itself is purely a product of Christie’s imagination, showcasing her exceptional storytelling skills.
