The German Woman

A conscientious objector loses his appeal and is later found dead in his cell. At the house of the judge who sentenced him, a young evacuee is killed by a booby-trap in the summerhouse. Foyle's investigation reveals a relationship between the judge's daughter, Susan, and a local worker, Peter. While guarding the judge, Milner is caught in an apparently compromising position by the judge and forced to leave - another murder follows as Foyle considers the actual purpose of the factory at which Peter works.
