Jonathan Pine thought he'd buried his past. Now living as Alex Goodwin - a low-level MI6 officer running a quiet surveillance unit in London - his life is comfortingly uneventful. Then one night a chance sighting of an old Roper mercenary prompts a call to action and leads Pine to a violent encounter with a new player: Colombian businessman Teddy Dos Santos. On this perilous new journey, Pine meets Roxana Bolaños, a businesswoman who reluctantly helps him infiltrate Teddy's Colombian arms operation. Once in Colombia, Pine is plunged deep into a deadly plot involving arms and training of a guerrilla army. As allegiances splinter, Pine races to expose a conspiracy designed to destabilise a nation. And with betrayal at every turn, he must decide whose trust he needs to earn and how far he's willing to go before it's too late.
