Alastair Sheridan has it all. Fresh faced and handsome, he's a self-made millionaire with a beautiful wife and children, and in the chaotic world of British politics, where heroes are in short supply, he has a real chance of becoming Prime Minister.

But Alastair Sheridan also has a secret. He's a serial killer with a taste for young women, and he's been killing for years, protected and abetted by some very powerful individuals.

Only a handful of people know what kind of monster he is, but disgraced detective Ray Mason, languishing in prison and awaiting trial for murder, is one of them.

And then, while being transferred between prisons, Ray's broken free by armed men and given an offer: assassinate Alastair Sheridan, and he can begin a new life abroad with a new identity. The men he's working for claim to be from MI6, and their reason for wanting Sheridan dead is that he's a threat to national security.

But, as Ray soon discovers, their motives are far darker than that. No one is who they seem, and the only person he can trust is his former lover, Tina Boyd, a battle-hardened ex cop with scores to settle of her own with Sheridan.

As Ray prepares to pull the trigger, with the police closing in on him and enemies on every side, only one thing is certain. No one wants either him or Tina to get out of this alive.
