“Instinct is a marvelous thing. It can neither be explained nor ignored.” — Agatha Christie In a quiet English country manor, a murder shatters the illusion of peace. The wealthy Emily Inglethorp lies dead—poisoned behind locked doors—and suspicion ripples through the family estate. Everyone has a motive. Everyone has secrets. And only one man has the brilliance to untangle the deadly web. Enter Hercule Poirot: the meticulous Belgian detective with a razor-sharp mind and a penchant for methodical deduction. In his very first case, Poirot must navigate a maze of lies, red herrings, and concealed motives to uncover the truth behind The Mysterious Affair at Styles. A masterclass in classic detective fiction, this is where it all began—Agatha Christie’s groundbreaking debut and the birth of one of literature’s most iconic sleuths.
