don't be dull, be fannish

Give me a hand, my dear friends. Mystery movie series - and by "movie" I mean at least 60min. long episodes, not regular 40-50min. I need your tips. Gimme!

I know of:

American: Columbo, Donald Strachey*, Jane Doe, McBride, Mystery Woman, Nero Wolfe, Perry Mason...

British: Cadfael, Foyle's War, George Gently, Hercules Poirot, Lewis, Luther, Lynley, Marple, Midsomer Murders, Morse, Sherlock, Vera, Wallander...

Australian: Miss Fisher...

Canadian: Detective Murdoch*...

German: Der Bulle von Tölz, Mit Herz und Handschellen*/**, Tatort...

* These feature a gay character in a prominent role (AFAIK).
** These were attached to a regular series.
