I've only recently discovered this detective series on BBC 4, and watched its third incarnation. Frankly, I can't quite undersatnd why so many have entered negative reviews.

Having to read sub-titles is a nuisance but well worth while. The story is coherent and well acted and there's little in the way of extraneous noise or scenes. The chief character, Louise, comes across as a bit of a troubled soul at times but watching her think as she considers her response to questions, or seeks knowledge from suspects, is well done.

The story in series 3 is a good one and I've been gripped from the outset - if I hadn't been, I'd have given up long before the end. It's not perfect but it's well worth a mark of 8, and much better than many of the formulaic offerings from elsewhere.
