PD James Mysteries: A Certain Justice. When a bitchy lawyer whose prowess in court is only matched by her ability to make enemies is murdered, Commander Adam Dalgliesh is soon on the case. This was the last of the original run of Dalgliesh mysteries with the great Roy Marsden from 1998. I haven't previously seen the last few as I heard the later ones just weren't as good as the 82-91 run, but based on this, I'm not sure why. Marsden is admittedly looking a bit long in the tooth at this point but he's still a great actor and, while shorter, it's still 3 50 minute episodes which is more than long enough to make it satisfying. I thoroughly enjoyed it personally...
