One of her lesser books, if I must say. The main character is retired policeman, Luke Fitzwilliam. Luke has discovered that an elderly woman who had professed to know something of murders in her village, has died, under mysterious circumstances, along with another villager. He comes to town, bent on discovering the identity of the killer. He spends most of the book ruminating over all the potential killers, ruling them out, and then putting them back under suspicion. There’s a strange romance, he involves himself in( Christie does have a habit of doing that once in a while,). The identity of the killer wasn’t much of a surprise to me. Luke doesn’t even play much into the discovery of the killer . This is billed as Superintendent Battle number four, but he hardly has a role in this book , he shows up for a couple pages and that’s It. It was a decent read, but nothing spectacular or memorable.
