These shows do a great job of creating an image of the British Home Front that is very different from the one romanticized in the history books. We get a very real feeling that the British public "knew" the war was lost in the darkest hour, yet still kept a stiff upper lip. This tension, combined with wartime secrecy, energizes the drama. The war is like the weather is in other mysteries; criminals often use it as cover for their activities (blackmarket petrol, draft dodging, burglary, blackmail, and the like hidden by blackouts, bombing raids, and official secrets) and it's the job of the police to uncover all of the layers. In doing so, Chief Inspector Foyle asks hard moral questions - even in wartime, when thousands are being killed every day, is murder murder? The "bigger picture" is often cited as justification by the criminals, and, through association, this paints the leaders of the war with the same brush. A great show for children - this can spark interest in the period while also teaching moral lessons. Unlike some nihilistic modern fare, Foyle's War strives to show moral clarity through the confusion.
