But the mystery sender knows too much--including the fact that during the war, Verity worked for the Secret Service, something not even Sidney knew.

Relying on little more than a coded letter, the help of a dashing stranger, and her own sharp instincts, Verity is forced down a path she never imagined--and comes face to face with the shattering possibility that her husband may not have been the man she thought he was. It's a truth that could set her free--or draw her ever deeper into his deception....
