Marine biologist Susie Cooper traded her life in America for a dream job on the rugged Scottish coast. Now all she lacks is the right man to start a family with. After their first meeting, she knows sexy Detective Inspector Nick Archer isn't what she's looking for. He's the type of guy whose idea of commitment is staying the whole night.
Nick has returned to St. Andrews for one reason only - to fulfill his vow to find his wife's killer. Relentless in his 12-year quest for justice, he has no problem using Susie to get close to his primary suspect: her boss. But the passion between them smolders, and as it ignites, Nick finds himself torn between his past and his present - with Susie.
When one of her boss's students is murdered, Nick's investigation draws Susie into a web of madness and betrayal. They will have to learn to trust each other if they're going to catch a killer... and come out of this alive.
