Cassie is the flight attendant of the title. She’s about as reliable a narrator as Rachel from The Girl on the Train . Overindulgence in alcohol causes her to black out, not pass out. After a one-night stand with a man she met on her flight to Dubai, she wakes up to find that he has been brutally murdered in the bed next to her. She’s pretty sure she didn’t do it, but not 100%. She runs from the hotel after cleaning up the evidence and it isn’t long after her return to the US that the FBI starts sniffing around her door. The subsequent action leads to shady international investment funds, Russian oligarchs, an international chase, and a rather surprising ending. Apparently this was made into an HBO miniseries, with some of the book’s details changed. I think I may give the TV version a try. It is a good story.
