Review of PBS' Foyles' War Season VII

"Foyles' War" begins a new season after being gone for a few years on PBS. The first episode "The Eternity Ring" ran Sunday night. Last time we met Chief Superintendent Foyle he was on his way after retiring to America. Five years have passed and it's now 1946 post-war Britain and he's in London (makes for easy back-drops). Many aren't aware but food shortages and rationing are still ongoing. They're discussing Social Security and a national health service. His driver, Sam, is back but things have changed. It's a much darker era and everything is serious (thank God for Sam who contributes to some lightheartedness.  MI-5 is recruiting Foyle and it's a different world order- "The Cold War."
