Poirot reveals to Race, Bessner, and Cornelia that Simon killed Linnet. The murder was planned by Jacqueline; the pair are still lovers. Simon married Linnet as part of their scheme to get Linnet's money. On the night of the murder, Jacqueline deliberately missed Simon, who faked his leg injury with red ink. While Fanthorp and Cornelia were distracted by Jacqueline, Simon took her pistol that she had deliberately discarded, went to Linnet's cabin, and shot her. He placed the nail polish bottle which had contained the red ink on Linnet's washstand, then returned to the lounge and shot his own leg. Simon used the stole to try to silence the pistol, loaded a spare cartridge to make it seem that only two shots were fired, and threw the pistol overboard. Louise and Mrs. Otterbourne were murdered by Jacqueline, who was warned by Simon when the plan was going awry – Louise witnessed Simon entering Linnet's cabin that night, and hinted at this to Simon when Poirot was interviewing her in an attempt at blackmail; Mrs. Otterbourne witnessed Jacqueline entering Louise's cabin before stabbing her. Poirot confronts Simon, who confesses. He is arrested, as are Jacqueline and Richetti. As the steamer arrives back in Shellal and the passengers disembark, Jacqueline shoots Simon and herself with another pistol she possessed, so they may escape the gallows. When pressed, Poirot reveals he had known she had a second pistol, but had sympathetically chosen to allow her to take her own life.
