Shetland and Vera are, agreed, terrific. Same author (Ann Cleeves) wrote both and her books are as interesting as the tv series are. Vienna Blood Season 2 just began on PBS - previously highly rec'd by Spek.
For those interested in foreign crime, I enjoyed Henrik Menkill's "Wallender" series that starred Kenneth Branagh as the morose and disaffected Swedish detective. The original Swedish version was a mess. Branagh is far better in the title role and Menkill's books and tv story lines are captivating. "Young Wallender" as a prequel on Netflix is a must miss.
I am watching and really like Netflix' Dutch crime series "Undercover" starring Frank Laemers as Ferry, a gangster living in a trailer park along with an undercover police team (Tom Waes) ingratiating themselves - both characters are intense, eyes on the prize, thinking about the game all the time. Season 3 began this week. One man is from the bad, the other from the good - both are skilled at what they are doing & trying to achieve. French "Spiral" is also one of the best foriegn tv crime series - superb acting, gritty plotting - alongside UK's "Line of Duty."
If you subscribe to MHZ channel or Amazon Prime, "A French Village" is worth seeking out. Its set on certain days in the same, well duh, French village during WWII and features many actors who appear in "Spiral".
Lest we forget...new season of "Ozark" starts this Friday!
