Season of Darkness by Maureen Jennings

All of England is shaken by the events of Dunkirk during World War II. When land girl Elsie Bates is murdered in the small rural village of Whitchurch, the relationship between the townspeople and the German nationals who are imprisoned at a camp outside of town becomes even more uneasy, even though the men are mostly intellectuals and don't seem to have Nazi ties. DI Tom Tyler of the Shropshire constabulary works with his colleagues to find out who would want Elsie dead. But when someone else is killed, a mild panic sets in. It soon becomes clear that there is a connection to the camp and maybe even a killer in its midst. Season of Darkness is the first book in this mystery trilogy. I really liked the characters and the setting of a English town in 1940. If you like historical mysteries, give it a try.
