'Silent Witness'. I didn't watch it until a few months ago, on iplayer. I'm currently up to 2019. Don't like Jack Hodgson, who's a thug, albeit a brainy one. Like Clarissa Mullery, but it's a pity about Liz Carr's illogical opposition to assisted suicide (nor that that's relevant to her thespian skill). Can be rather depressing.
Also 'Foyle's War', another I'd never seen until a week or two ago. The eccentrically-named Honeysuckle Weeks is excellent as a typical 1940s jolly-hockey-sticks posho, and Michael Kitchen is a master of deadpan understatement, especially when casually telling a wrong 'un that they'll probably hang. Love the general period feel, esp. all the lovely old cars and railway engines.
