The original Taggart, with Mark McManus, was a great favourite of mine. I'd also love to see Butterflies, Ever Decreasing Circles and a series called Gangsters, from the mid-1970s, set in Birmingham, which starred an actor called Maurice Colbourne and also Paul Barber. It was pretty violent, I recall, but very gritty and exciting and I was deeply in love with Ahmed Khalil who played the policeman (sigh).
Baby Reindeer - anyone watched it?
