The Cruise Ship Murders A series of murders besets the four thousand passengers on a luxury cruise ship headed to Honduras, Belize, and Mexico. Sadie and Nathan Weinstein have sold their Brooklyn grocery and relocated to a senior community in Florida. Sadie, a zany amateur sleuth in the past begins an investigation, but she also becomes a suspect herself. Enlisting help in cracking the case, she organizes the Cruise Ship Murder Squad. The visions of Rhajmah, a pickle-eating psychic, are indispensable. Nathan, calling the ship a "boat" consistently, warns his wife to mind her own business. But Sadie doesn't listen even in the face of life-threatening danger. The action takes place in the casino, the buffet, the infirmary, and on many decks. It was not a relaxing cruise to be sure.
