It could be Second Sight (though I don't especially remember watching that and none of the episodes seem close). Frost, Silent Witness and Heartbeat are out. One I thought about was the remake of Randall and Hopkirk and Deceased but none of the episodes of that seemed close either. I also don't recall the less talented one from Robson and Jerome being in it so probably not Touching Evil.

I don't want to put you to too much work so you don't have to go through all your old magazines if you don't want. Besides, the rate that I watch and contribute detective movies I'll probably end up watching it myself before long.
