Cast

While viewers have seen dramatic exits from a number of characters through the years, who might be in series 6 is not certain. With cliffhangers and several plot lines still open from the series five finale many of the main characters would be expected to appear in plot.

The main cast includes:
Detective sergeant Steve Arnott (Martin Compston)
Detective inspector Kate Fleming (Vicky McClure)
Superintendent Ted Hastings (Adrian Dunbar)

As well as:
Detective inspector Matthew "Dot" Cottan (Craig Parkinson)
Detective chief inspector Anthony "Tony Gates (Lennie James)
Detective inspector Lindsay Denton (Keeley Hawes)
Sergeant Danny Waldron (Daniel Mays)
Detective chief inspector Rosanne "Roz" Huntley (Thandie Newton)
Detective Sergeant John Corbett (Stephen Graham)
Detective Chief superintendent Patricia Carmichael (Anna Maxwell Martin)

Plot details

For fans of the show, the burning question will be the identity of 'H' - a corrupt cop (or is it cops, plural). The forthcoming season six is likely to delve further in the matter.

Another twist from the series five finale leaving viewers with a cliff hanger ending is a revisit to Dot's death, where a Morse code message may have major implications.

And speaking of the deceased, more unanswered questions are surfaced in regards to the death of detective sergeant Corbett and who's responsible for the leak.

That's not to mention Hastings laptop -- and what may or may not be illicit content.
