By Agathe Christie.

Poirot was passed over for this one. Anne Beddingfeld 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. There is a murder in England the next day, and the murderer attempts to kill her on the ship en route to Cape Town. The setting for the early chapters is London. Later chapters are set in Cape Town, Bulawayo, and on a fictional island in the Zambezi. The plot involves an agent provocateur who wants to retire, and has eliminated his former agents.
