Can you recommend some detective novels or movies that take place on a ship?

Ask for recommendations
The main story takes place on a ship. It can be a nautical/naval/naval type.
Better be a mystery novel
If it really doesn't work, other types are fine too, such as "2012" and "Zheng He"

Answer 1

"I recommend 'The Ultimate Killer.' It's a mystery detective novel. The story takes place on a boat and tells the story of a red dress that was thrown at the scene of a murder. It also tells the story of a serial rape and murder case that happened a few years ago. It involves the capable captain of the criminal police, Ning Zhiyuan, and the young female surgeon, An Jing, who are two unrelated people. I hope you like this fairy's recommendation. Muah ~😗
