Now that we've tipped the plot into the coldwar era, shady dealings abound and there are some tricky blighters about.
Wonderful production stuff, costumes, sets, etc. I do think that it's hard not to taint "period" style with current fashion but they did manage the period jolly well. Don't often watch retro crime but have always had a soft spot for "Foyle's War" and so I really do hope we have some more.
Jolly good show, I say.
