Yes, it's long and I watched it all in one go (far longer than the average movie) and you could argue that it is perhaps too much so, but really it doesn't matter in the end. This is a very effective crime drama with a compelling lead character in DS Pirie who is refreshingly filled out as a rounded person. Ever since the success of reality based police procedurals such as "24 Hours In Police Custody", I've noticed a real effort in fictional police dramas to dial down the melodrama and present a more convincing portrayal of the reality of such work and this show very much falls into this category. That said, the plot is knotty and unconvincing in parts with simply too many extreme occurrences, but, again, that really doesn't matter that much. It's a puzzle to be solved as are most crime dramas and it's handled well. In addition to Lauren Lyle's superb portrayal, the standard of acting is high throughout. Very nicely photographed as well. The music is mostly of the now-becoming-clichéd synthesizer ambient variety but with some good use of pop songs such as Pulp's "Common People". I really enjoyed these three episodes.
