Poirot and the brave and loyal, but perennially clueless, Captain Hastings travel to France at the behest of a mysterious millionaire who turns up dead before he can explain why he wrote so urgently to Poirot.
This is Poirot’s second appearance in a Christie novel, but he has already developed a disdain for the forensic methods he espoused in his first novel, The Mysterious Affair at Styles. Indeed, Poirot derides the French detective who examines every inch of the crime scene for hair and other clues as a “human bloodhound.”
This story had me grasping at red herrings until the end, and we learn something important about Hastings in the process! Highly recommended.
