Looks intriguing. Lovely post-war setting, interesting plot and good leads. Reminds me a little of the film adaption of Enigma. Looks like an excellent drama of the type British TV used to do so well. Doesn't look like it's trying to impress, as The Shadowline sometimes did.
Worth a wee look if you missed it.
