Stella Whitelaw - Fold and Die (audiobook)

Jordan Lacey, Latching's zany but intrepid private eye, goes cruising to Norway and the spectacular Midnight Sun. But she is the undercover bodyguard of Joanna Carter, a woman who believes that her life is in danger. A set of curious events culminate with Jordan on the run and being charged with Joanna's murder. In desperation Jordan emails DI James for help.
Storms at sea, gale force winds, a mysterious grey man, a disappearing Thai stewardess and a doddery old lady who calls herself Miss Phoebe Brown accentuate the twists and turns of this fast moving plot aboard a supposedly leisurely cruise.
