Respected Manchester GP Dr Don Halliwell is discovered brutally murdered one cloudy Autumn morning. Shot dead on the front door of his own practice, his shirt soaked in blood.

Then his colleague Dr Fraser McKee goes missing. McKee's car is found at his home, violently smashed up. There's blood inside.

That night McKee walks into the police station. 'Somebody's trying to kill me.'

But just as Detective Janine Lewis is following McKee's trail, shocking new information comes to light. McKee and Halliwell had been seen screaming at each other, that very evening before Halliwell's murder.

Is McKee really in danger, or is he trying to cover his tracks?

As the case continues, it becomes clear that there's much more to both McKee and the late Halliwell than meets the eye. They both had more than one enemy, bloodthirsty for revenge.

It's up to Janine to separate the murky truth from the lies - will she be able to find the killer before it's too late . . . ?
