Easily the best season, so far.

100% on Rotten Tomatoes.

A surprising and intense finale.

The series follows Superintendent Ted Hastings (Adrian Dunbar), D.S. Steve Arnott (Martin Compston) and D.C. Kate Fleming (Vicky McClure) as they lead an investigation into the corrupt actions of Sergeant Danny Waldron (Daniel Mays).

This series’ supporting cast includes Craig Parkinson as D.I. Matthew “Dot” Cottan and Polly Walker as Gill Biggeloe. Keeley Hawes reprises her role as D.I. Lindsay Denton.

Every actor is great. Hawes was nominated for the BAFTA TV Award for Best Actress award for this role.
