Everyone is in peril. Everyone is a suspect. It's 1925 and the Empress of Australia is making her regular Atlantic crossing, New York-bound, with a full manifest of passengers. When a dead body is uncovered onboard, it is up to Inspector Archie Daniels to find the killer. But solving one murder quickly turns into solving two, then three, and it becomes clear that Daniels must act fast to avoid an all-souls-lost-level calamity. No one, from the horrendously wealthy and entitled first-class passengers to what they would consider the dregs of empire below deck, is safe. And no one can get off . . .
