Inspired by the author’s own experience, The Vicar introduces Terry Nolan, an M15 operative who, when he discovers his cover is blown and millions of lives are at stake, will do whatever it takes to stop enemy forces.

Terry Nolan, an off-the-books MI5 operative known as the Vicar, has been officially dead for the past thirty years. But when Nolan is attacked in Boston, it becomes clear his cover is blown. Even worse, his Parishioners—the network of spies who work under the Vicar—have all been compromised.

Nolan races to New York to try and find his last remaining agent, Shae, whom he personally recruited years ago. Instead, he finds Kristen, a young civilian who is determined to save Shae, too—and who may know more than she’s letting on.

In the search for his missing agent, Nolan intercepts intelligence that indicates weapons of mass destruction are on their way to Britain’s four largest cities. Working directly with the ruthless head of MI5, Nolan must call upon all his clandestine skills to save the final Parishioner and find out who is behind the attacks and why. But he’s playing a dangerous game, and the dark secrets of his past are about to catch up with him.
