The Woman in Cabin 10

Investigative journalist Laura "Lo" Blacklock is recovering from a traumatic episode: a woman that was the subject of her piece was drowned for speaking to her. She takes on an assignment aboard the maiden voyage of the luxury superyacht Aurora Borealis, owned by Norwegian tycoon Anne Bullmer and her husband Richard. Anne is dying from leukemia, and Lo is to write a story about the yacht full of billionaires going to Anne's fundraising gala.
