Having retreated to the idyllic Polynesian island of Bora Bora to savour and lament the lost past, Harry Lindstrom finds himself drawn into a strange relationship with a raven-haired, B-list movie actress and her invalid husband. Harry learns from the amiably grotesque Inspector Theophil Queequeg that they are leaders of a virulent religious movement, and that the woman is far more dangerous than he could ever have imagined. Back in Toronto, she reappears with a disturbing capacity to make Harry wonder about the moral justifications for murder. Separately, they travel to England where they challenge the horrific intentions of the cult. Lindstrom Unbound is the final book in a trilogy, following Lindstrom Alone and Lindstrom's Progress.
