The fourth book in Chris Ryan's Extreme series.

The Chris Ryan Extreme books take you even further into the heart of the mission with more extreme action, more extreme language and more extreme pace. Like Call of Duty or Medal of Honour you'll feel part of the team.

Chris Ryan Extreme: Silent Kill has previously been published as four separate shorter missions. Now in one book to keep you at the heart of the action.

Northern Ireland, 1993. For high-flying MI5 officer Avery Chance the real war has only just begun. When Chance is abducted by the IRA's notorious Nutting Squad, her hopes lie in the hands of a young SAS recruit who must risk everything to bring her home.

Twenty years after his act of self-sacrifice in Belfast ex-SAS legend John Bald is a scarred shadow of his former self. But when a face from the past appears and rescues him from deep trouble, Bald is offered one last shot at redemption. His target is Kurt Pretorius, a ruthless mercenary operating deep in the wilds of war-ravaged Somalia.

In a world where rogue mercenaries operate beyond the reach of the law, Kurt Pretorius has transformed himself into a god. It is up to Bald to stop Pretorius before he turns Somalia into a terrorist haven. But Bald quickly finds himself sucked into a twisted game of survival, where the stakes could not be higher - and the price of failure is his life...

With time running out, Bald must kill Pretorius before he brings down everyone around him. It's a mission Bald was born to do. Because sometimes, the only way to beat your deadliest enemy...is to be like your deadliest enemy.
