Death on the Nile

On board a steamer cruising the Nile in Egypt, Simon and Linnet Doyle are on their honeymoon, but they are being stalked by Jacqueline de Bellefort. She was engaged to Simon, when she introduced her old school friend Linnet to him - and Jacqueline is bitter about being cast off. Poirot is also on board the steamer, but nevertheless the cruise turns into a series of killings for him to solve.
