Anne Beddingfeld is on her own and ready for adventures when one comes her way. She sees a man die in a tube station and picks up a piece of paper dropped nearby. The message on the paper leads her to South Africa as she fits more pieces of the puzzle together about the death she witnessed, a murder in England the next day, and attempts to kill her on the ship en route to Cape Town.
Reviews were mixed at publication, as some hoped for another book featuring Poirot, while others liked the writing style and were sure that readers would want to read to the end to learn who is the murderer.A later review liked the start of the novel, and felt that the end did not keep pace with the quality of the start, and the reviewer did not like when the story became like a thriller novel.
