Foyle’s War is a British detective drama set in the 1940s, where Detective Chief Superintendent Christopher Foyle investigates crimes like murder, theft, and black market activities in the English seaside town of Hastings during World War II. The series focuses on the “war on crime” on the home front, often involving interference from military and intelligence services and featuring plots tied to real historical events of the war. Later seasons show a retired Foyle working as an MI5 agent in the aftermath of the war.
