Absolution

1984 - It looked like a simple job.  That was why they gave it to him.  Guarding a woman - nameless and almost faceless after a savage acid attack - at a Glasgow hospital, PC Alan McAlpine has no idea that this simple job will haunt his career and change his live forever.

2006 - Two decades later, Alan steps into Partickhill police station and back in time.  Now a celebrated Detective Chief Inspector, McAlpine has been drafted in to lead the hunt for a man the press are calling the 'Crucifixion Killer'.  Two women are already dead, their mutilated bodies displayed with arms outstretched.
