When Hercule Poirot is summoned to the quiet English suburb of Hawthorne Lane, he finds the community unsettled by a shocking and ritual-like murder. The case appears simple at first, but beneath the polite façades lie buried secrets, simmering grudges, and a trail of clues only Poirot’s unmatched order and method can untangle. As suspicion spreads and tensions rise, Poirot must navigate tangled relationships and hidden pasts to expose a killer who is far closer—and far cleverer—than anyone suspects.
