Very similar to the Harrison Ford offering, but, at least there is a motive for our protagonist-cop to resort to violence. (Harrison had no clear motive to have brutally murdered HIS wife, although the 'she was more rich' is proposed.) One of the lessons a skilled detective SHOULD know is: don't tamper with the crime scene since that may link you to the homicide via forensics. However, in neither film does that slip-up create any irresolvable issues.
We know John Simm (a Martin Freeman DR WATSON doppelgänger) from LIFE ON MARS & GRACE. For this role, there's a lot of faces to put on, but, above all, is he shrewd enough to stay on the loose & put the pieces together as to who framed him? I am only in Episode 2, so, no spoilers here. The character actor Craig Parkinson can be be counted on to be slippery (he played the 'crooked cop' in LINE OF DUTY). And is there a Brit cop show without P. Glenister? Action-packed so far, with twists & turns. 8/10 (bit of language).
