Mackenzie Clarke, a police officer living abroad (that is, far from her home country) in London, is forced to return temporarily to Dolphin Cove, Australia, the town where she grew up. When a murder occurs, Mack can’t resist the urge to put her investigative skills to use. This return to her roots (in other words, the place where she belongs) brings back a flood of memories—some pleasant, some not—and leads to some rather awkward reunions, particularly with her former fiancé Glenn, whom she abandoned on their wedding day, as well as with her former mother-in-law, who was also her boss and who heads the town’s police station. This idyllic setting, located on the coast of New South Wales (a state in southeastern Australia), is the scene of complex murders, which Mack will strive to solve with the help of her new team: Lieutenant Colin Cartwright, an Englishman living in Australia; Officer Felix Wilkinson; and Reggie Rocco, a former teacher who has become a volunteer (meaning she helps out without pay) with the police department.
