Detective Inspector Ray Lennox has fled to Miami to escape the aftermath of a mental breakdown induced by occupational stress and cocaine abuse, and a harrowing child-sex murder case back in Edinburgh. But his fiancee Trudi is only interested in planning their wedding, and soon Lennox cast adrift, alone in Florida. A coke-fuelled binge brings him into contact with another victim of sexual predation, ten-year-old Tianna, and Lennox flees across the state with his terrified charge, determined to protect her at any cost. But can Lennox trust his own instincts? And can he handle Tianna, while still trying to get to grips with the Edinburgh murder?
