In his third adventure, private eye John Caine is in trouble again--only this time it comes looking for him. After saving a California woman and her corporation from certain ruin and acquiring his new home, a classic sailing vessel christened Olympia, he's back in his Hawaiian paradise, working hard at relaxing on the beach and trying to keep to the peaceful side of the street. But a woman named Margo Halliday is about to turn Caine's peaceful world upside down. One night, as Caine is leaving a neighborhood restaurant/bar, Chawlie's, he encounters a naked woman fleeing from a man who is shooting at her, but fortunately not doing a very good job of hitting his target. Caine easily disables the man and ushers the woman back into the restaurant. The woman, he discovers, is Margo Halliday, and the man, who quickly fled the scene, was her abusive ex-husband. Caine has almost forgotten about the incident when, months later, he reads about the murder of Margo's ex, who has been found shot to death in her exclusive Hawaii Kai condominium. And the next thing Caine knows, Margo is at his doorstep begging him to hide her from the thugs who murdered her ex and who she now thinks are after her. Desperate to get off the island of Oahu, Margo enlists Caine's help and unknowingly lead him into a lethal game that begins with shots aimed at them with high-powered rifles and leads them deep into the jungles on the island of Kauai, alone and outnumbered against the deadly assassins.
