This novel's protagonist is chastised by its narrator for his habit of using "derange" to mean "disturb." One subplot involves the suspicion that Mrs. Ferrars poisoned her husband to marry the title character, while another deals with Flora's ring, discovered on the path behind the house. Its solution relies on the deduction that the victim's voice was being played by a since-removed Dictaphone, and that suspicious stepson Ralph Paton was being hidden away at a local inn by the real killer. Though its protagonist would star in over forty more books, at its start he's already retired to grow marrows in King's Abbot, where he meets Dr. James Sheppard, the man that serves as his new sidekick and chronicler until the twist ending.  For 10 points, in what novel does Hercule Poirot discover that the narrator killed the title character?
