Travel journalist Lo Blacklock has just gotten the assignment of a lifetime: a week on a luxury cruise to see the northern lights in Norway's fjords. The guests are fancy, the parties are full of booze and laughter, and the cabins are so nice. As they cruise on, Lo witnesses someone being thrown overboard. But when all the guests are still accounted for, the mystery truly begins. Lo won't let go what she saw, and is determined to solve what happened.
The Woman in Cabin 10 is supposedly being adapted by CBS Films, but there hasn't been any further news since 2017.
