At the height of World War II, Thomas Littlejohn investigates a factory boss's murder Once, Henry Worth's sprawling factory was filled with looms and textile workers, but since the onset of World War II, the space has been given over entirely to military production. Worth is walking the grounds late one night when he smells gas coming from an unused shed. When he enters to investigate, the door slams and locks behind him. He is dead in minutes. Detective-Inspector Littlejohn is called down from London to investigate the murder and finds the entire town upended by the question of Worth's inheritance. Three children and a wife are feuding over the man's fortune, and they are not afraid to kill to get their share. As British troops fight and die overseas, Littlejohn finds that the fiercest battlefield of all may be on the home front.
