Just finished Foyle's War season 1.
Late to the party since it came out in 2002, but it was excellent, if you like historical murder mysteries. Very old-fashioned, which is good for a series that starts out in 1940.
Season 1 also had some big stars when they were young and not stars yet. Rosamund Pike, James McAvoy, Tobias Menzies (Outlander), Sophia Myles, and David Tennant.
Now I've started on the series Mare Of Easttown, starring Kate Winslet. Three episodes into it, and it too is excellent. Police detective/murder mystery.
According to the shows producer, Mare Of Easttown will only be the one season, unless a great plot comes along and the actors want to get back onboard.
