For Detective Chief Inspector Ryan, the stakes have never been higher. Most of the world thinks he's dead, killed by an assassin's rifle in his own home. But another man took the bullet intended for him, and now Ryan's living on borrowed time. As long as he stays 'dead', in the sanctuary of his parents' home in Devon, there's a chance to find the people behind the deadly killing network. It's only a matter of time before his secret's uncovered, and nowhere will be safe. Back in Northumberland, Ryan's team are called in to investigate the mysterious death of a man in Alnwick, who collapsed yards from the walls of its Mediaeval castle. When a second person is rushed to hospital with the same symptoms, her life hangs in the balance unless they can discover the toxic substance that's killing her. For DCs Lowerson and Reed, there's only one place to look for inspiration - the Poison Garden.
