I was somewhat worried that this episode might deviate too far from the original book, especially as "The Shadow in the North" is my favourite of the Sally Lockhart quartet. However, I was pleasantly surprised, it stuck extremely close to the book and really brought Philip Pullman's creation to life. The acting was superb, Billie Piper as the Financial Consultant-cum- detective Sally Lockhart was very convincing as the feisty, yet vulnerable young woman who is pulled into a dark underworld of corruption and murder. Equally, Jared Harris as evil tycoon Axel Bellman was great- understated yet chilling, just as Pullman envisaged him. I can't fault the script or pace of it either, it was gripping but managed to obtain the essence of dialogue/ storyline without leaving out anything significant, and some adaptations might tend to do. Overall, highly enjoyable and entertaining, a worthy adaptation of Pullman's great story!
