The Quisling Factor

Treason. Espionage. Revenge. In the aftermath of WWII, ex-intelligence agent Tore Haugland tries to adjust to life in his newly freed country with the woman he loves. But he still has to testify against a Norwegian traitor—one of the monsters of the German occupation—whom he helped to capture.
When mysterious notes threaten Haugland and his family, he must choose between protecting them or bringing to justice the man who tortured him and destroyed the village that hid him. Challenged by injuries and recurring nightmares, he will have to rely on his former training and old Resistance friends to rescue his wife from the traitor who will do anything to keep Haugland from testifying.
