Revenge of the Saboteur

In The Hunt for the Saboteur, Landon Garland's first book, two saboteurs are brought ashore from a German U-boat off the coast of Virginia in 1944. One is caught. The other escapes and becomes a spy for the Soviet Union until he is caught in 1949.

In The Revenge of the Saboteur, the saboteur/spy, Jack Dillard, escapes and is hunted by the FBI, CIA and the KGB33, managing to reach England working as a steward aboard the Queen Mary. He returns to America in 1951, seeking revenge against four men who were responsible for his 1949 arrest. One by one, with murder in mind, Dillard stalks these men through England and the United States.

Tom Fisher, the retired FBI agent responsible for Dillard's arrest in 1949, joins the hunt, and with the help of an MI-6 agent, tracks Dillard to a surprising ending.
