Beacon of Vengeance — Patrick W. O'Bryon

As America edges closer to engagement in Hitler's war, reluctant operative Ryan Lemmon returns to Nazi Europe. His covert assignment targets Reich operations in Paris, but a cry for help from friends in a fascist internment camp must take priority. Occupied France teems with dangers: an agent of British Intelligence whose help may prove deadly, a beautiful partisan whose cold heart threatens his mission, a former lover trapped between Gestapo persecution and the violent Parisian underworld. But most threatening of all, a ruthless personal enemy lurks, awaiting his moment of revenge. Beacon of Vengeance is the powerful sequel to the award-winning thriller Corridor of Darkness, A Novel of Nazi Germany, described by Kirkus Reviews as "...an intriguing early WWII spy yarn set in a well-researched, authentic Germany."
