The Younger Son is a big fan of Michael Kitchen and of the Foyle's War series and suggested we watch Bleak Midwinter sometime this month. It's not a typical Christmas story, but the fate of a Christmas turkey is a key plot element.
Youtube has this online in short segments with embedding disabled. Part 1 is here, and other parts are linked from there.
There is a detailed plot synopsis and some screen shots here. The Younger Son is slowly but surely collecting these on DVD. He has 5 seasons so far, I think.
