Invasion; Bad Blood; Bleak Midwinter; Casualties of War

I love the characters and the series, they work well together and their lives are well drawn. Foyle continues to be a man of integrity and deals with a variety of situations in interesting and clever ways, sometimes the war effort gets in the way and you can see his frustration with politics.
And I love his driver, Samantha Stewart, played by Honeysuckle Weeks. ( )
