Death by Water (Miss Fisher's Murder Mysteries Book 15)

Phryne Fisher boards the S.S. Hinemoa, a luxury cruise to New Zealand, to investigate a series of jewelry thefts from first-class passengers. P&O executives are concerned that the thefts—likely committed by someone aboard—will damage the cruise line's reputation. Fisher, known for her bob haircut, green eyes, and pragmatic approach, is well-suited to move among the upper classes and solve the case. She carries the Great Queen of Sapphires, the Maharani, as bait. During the voyage, shipboard romances, champagne cocktails, erotic photographers, jealous suitors, drugged drinks, jazz musicians, blackmail, and an attempted murder all unfold. The thieves eventually discover what many before them have learned: that resisting Phryne Fisher's intelligence and charm proves futile.
