Hercule Poirot solves his first case in the Agatha Christie novel that started it all, now in a fully restored edition that features a “missing chapter” along with commentary from Christie expert John Curran. Who poisoned the wealthy Emily Inglethorp and how did the murderer penetrate and escape from her locked bedroom? Suspects abound in the quaint village of Styles St. Mary—from the heiress's fawning new husband to her two stepsons, her volatile housekeeper, and a pretty nurse who works in a hospital dispensary. With impeccable timing, and making his unforgettable debut, the brilliant Belgian detective Hercule Poirot is on the case.
