1. Age is catching up with Robert Finlay, a police officer on the Royalty Protection team based in London. He’s looking forward to returning to uniform policing and a less stressful life with his new family. But fate has other plans.

A policeman is killed by a bomb blast, and a second is gunned down in his own driveway. Both of the murdered men were former Army colleagues from Finlay’s SAS regiment, and a series of explosive events makes it clear that he is not the ordinary man that his colleagues and new family think he is. And so begins a game of cat and mouse in which Finlay is forced to test his long-buried skills in a fight against a determined, unidentified enemy.
