A ring of German spies threatens the coastal town of Folkestone, England. Newly-recruited agent Ben Dorroll must uncover which British citizens are traitors to their country. When his first attempt at espionage falls prey to a trap laid by German sympathizers, the security of the British Secret Service is threatened. Feeling lost in a strange country and aching for a steady place to call home, he wants to resign and go back to his American medical work. But when he learns that his family identity holds the key to capturing the spy ring, Ben has no choice but to unite with the mysterious Jaeryn Graham so that the truth can be discovered.
In the aftermath of the Irish Rebellion, Jaeryn Graham’s British colleagues look warily on his Irish background. Always up for a challenge, he thinks his new mission in the Secret Service should be an opportunity to prove his prowess. But after encountering death and alienating two agents, he finds the road to victory isn’t as easy as he thought. Unless he can win the loyalties of his newest assistant, Ben Dorroll, his secret ambitions and his perfect success record will be destroyed.
