Stegs Jenner has always lived on the edge.
No ordinary cop, he's never happier than when he's working undercover, consorting with criminals and fighting to bring them to justice. But suspicion falls on him when he strikes out on his own and the operation he's involved in goes horribly wrong.
DI John Gallan and DS Tina Boyd are called in to investigate.
What they cannot know is that their enquiries will take them both into the heart of one of London's most notorious criminal gangs - and one of them into the rifle sights of the enemy.
