Here is Hercule Poirot’s last case, the triumphant climax to his long and brilliant career. The shrewd little Belgian detective has returned to Styles Court, the scene of his first English adventure in crime. But now the handsome country mansion is a guest house and Poirot, old and arthritic, is one of the guests. He invites his friend Captain Hastings to join him and then reveals the reason for his request.
Someone at Styles is responsible for several murders, someone the law cannot touch. And soon, Poirot said, a murder would be committed at the guest house.
Could Poirot and Hastings trap the guilty person? Poirot was resolved to try. But Hastings was investigating with one hand tied behind his back, for Poirot refused to disclose the name of his suspect, merely promising that Hastings would be given clues. Then there was a death at Styles — but was it murder?
