Episode 3: Bettany sails into Luxor, where ancient Egyptians buried their pharaohs in the Valley of the Kings for 500 years. The cemetery includes the boy-king Tutankhamen, but Bettany is just as keen to explore the Workers' Village, where generations of skilled tomb-builders lived. After taking in the giant Karnak Temple, she crosses paths with the steamship SS Sudan, which once hosted Agatha Christie.
