You might also want to check out the following:
“Touch of Frost” and
“Wire in the Blood”
Both are excellent series.
Frost is all on Netflix streaming (good)
There are only a couple episodes of Wire in the Blood floating around on the usenet.
I have a friend in the UK who regularly tells me what he is currently watching. Pointed me to some very good programs I probably would have missed otherwise.
Get on youtube and try some “Rab Nesbit”. Incomprehensible Scot accents. He says even the English can’t understand them LOL
