ship and books passage on it. On board the ship, Anne meets Suzanne Blair, Colonel Race, and Sir Eustace Pedler and his secretaries, Guy Pagett and Harry Rayburn. Colonel Race recounts the story of the theft of diamonds some years before, attributed to the son of a South African gold magnate, John Eardsley, and his friend Harry Lucas. The friends joined the war where John was killed and his father's huge fortune passed to his next of kin, Race himself. Lucas was posted as "missing in action". Anne and Suzanne examine the piece of paper Anne obtained in the Underground station and realises that it could refer to cabin 71, Suzanne's cabin, originally booked by a woman who did not appear. Anne connects finding the film roll in Mill House with a film canister containing uncut diamonds that was dropped into Suzanne's cabin in the early hours of the 22nd. They speculate that Harry Rayburn is the Man in the Brown Suit. In Cape Town, Anne is lured to a house at Muizenberg, where she is imprisoned but manages to escape the next morning and returns to Cape Town to find that Harry is wanted as the Man in the Brown Suit and has gone missing. Pedler offers Anne the role of his secretary on his train trip to Rhodesia which she accepts at the last second, and is reunited on the train with Race, Suzanne and Pedler, who has a new secretary named Miss Pettigrew. In Bulawayo, Anne receives a note from Harry which lures her out to a ravine near their hotel. She is chased and falls into the ravine. Almost a month later, Anne awakens in a hut on an island in the Zambezi with Harry Rayburn, who rescued her. Anne and Harry fall in love and Harry tells her his side of the story revealing that he and John were both in love with Anita / Nadina who cheated them. Carter, her husband fell to the track on the shock of seeing Harry again. Harry admits that he is the man in brown suit but denied that he killed Anita. Harry's island is attacked, but the two escape, and Anne returns to Pedler's party. They exchange codes to be used in future communications so that neither can be duped again. She receives a telegram signed Harry telling her to meet him, but not using their code.
