Cruise Ship Murders is the story of two retired police detectives and their wives that are taking a world cruise to all seven continents after their retirement.

The first welcome aboard cocktail party is to introduce the captain of their ship and her crew, and she turns out to be one of the detective's best friend's, from childhood. That his wife and working partner had never heard of.

The next surprise is, there is a murder on the ship, and the captain asked her friend and his partner to take charge of the investigating, since the security staff were not trained to handle a murder investigation.

The cruise takes them to all the places they wanted to see around the world and the murders of women keep happening.

They have almost no clues except one good looking man that all the women on the ship were attracted to. Was he the killer?

The women who were killed had all been see with him, yet everything about him said that he wasn't the killer. Was he the one that killed these women or was he somehow the cause of them being killed?

This would be one of the tough cases for the retired detectives to find who murdered these women that they ever had.
