Seth Mornay, an ex-Royal Marine, returned home two years ago to start a new life working for the Grampian Police Force. Now a detective sergeant with the Criminal Investigation Division, Mornay is more interested in seducing women than clearing his open cases -- much to the disgust of his partner, Constable Claire Gillespie, the one woman Mornay has put off limits. Early one misty morning, the body of a woman is found brutally stabbed in an old church graveyard, a broken garden stake lying nearby. Charged with solving the bizarre crime, Mornay struggles to break a case that seems to have no pattern. But as he discovers unexpected ties to an unsolved case from the past, the attacks accelerate. With a jealous and vindictive supervisor undermining him at every turn, and complications from his personal life threatening to destroy his career, Mornay finds himself racing against time to stop the killer from striking again.
