The Mysterious Affair at Styles (1920), Agatha Christie's debut novel, introduces the brilliant Belgian detective Hercule Poirot. Set in wartime England, the story unfolds at Styles Court, where wealthy widow Emily Inglethorp dies from strychnine poisoning. Narrated by Captain Arthur Hastings, the tale follows Poirot as he investigates a household of suspects: a much younger husband, resentful stepsons, and a sharp-tongued companion. With misleading clues, tangled alibis, and a dramatic courtroom revelation, Poirot unravels a chilling conspiracy driven by greed and betrayal. This classic whodunit launched Christie's legendary career and helped define the golden age of detective fiction.
