Shetland, ITV series

This is a really "great" detective series from ITV - one really needs to view the first 2 seasons, which are in one box set.  Also, dialect might be an issue with some viewers. This series - 6 episodes on 2 discs - is a continuing saga, so at the end of each segment, well Cliff Hanger comes to mind, you want to continue.

Archie Panjabi, who starred in CBS's "The Good Wife" series makes her debut in this season, it would appear that her character might be continuing.

The series is based on Ann Cleeves' bestselling books.

Give it a try!
