Soon after World War II, two former co-workers in the operations room of a Royal Air Force squadron meet in the street. Their lives have diverged dramatically but each wants to get rid of her husband. And so a mutual-assistance pact is made.

Rose and Antonia had a good war. As WAAF plotters they had all the excitement and independence of a difficult and fulfilling job, and all the fun of being two women on an RAF base. But peacetime is a disappointment. Rose’s war-hero husband has turned brutal out. Antonia, bored with her rich manufacturer, wants to move to America with her lover.

But what are plotters for, if not to plot? Antonia’s ruthless scheme would give them what they both want. If Rose doesn’t lose her nerve, they could get away with murder.
