Originally published in 1929, a Golden Age classic murder mystery set on a cruise ship - the perfect holiday read! Everyone is a suspect. When a beautiful countess is found strangled in her cabin aboard the luxury liner Latakia, scientist, explorer, and former intelligence officer Walter Ghost tries to find the killer. He has a taste for puzzles and a habit of getting into trouble, but now he's trapped in a game he doesn't know if he can win. Anyone could be next. Confined to the close quarters of 'B' deck, with a group of paranoid passengers, Walter must solve this one quickly - and find the killer before someone else gets scratched off the passenger list.
