A gritty emotional rollercoaster about the hunt for a serial child killer. Set primarily in and around Edinburgh. My wife and I found it disturbing but at the same time engrossing. Dougray Scott's portrayal of the obsessed cop DI Lennox was riveting and I can't imagine what he had to how through to play the lead character. The language is rive with typical Scot's dialect. For those not familiar, I recommend that you watch it with subtitles on.
