Martin Shaw is a great Dalgleish: very humane. There were several other excellent performances. The portrayal runs close to the book and the characters very convincing for the most part. My only real disappointment was Victoria Scarborough's portrayal of Inspector Kate Miskin. Her smirking during the interviewing of two of the characters in particular was actually very distracting, and it was good for one of them to put her in her place. That didn't fit with my remembrance of the book. Also I cannot imagine anyone giving answers to a police officer who acted in that way in real life. It smacked too much of the 'good cop/bad cop' which appears too frequently in fictional films. Overall though, it was a great two part film.
