I accept that New Tricks did rather lose its way in later seasons, and the loss of Alun Armstrong was a big nail in the coffin. However, the criticism in one of the reviews that this episode focuses more on Strickland than the rest of the regulars I don't accept as an issue. I am a Dr Who fan and one of the best episodes is The Weeping Angels and this is billed as a 'Dr Who Lite' episode because he doesn't feature in it much. I think it does some good for any long running series to have story lines that aren't always heavy on the main cast. That said, this is just a great episode on its own - not only do we see a bit more of Strickland, we have Tim McInnerny playing the MI5 role really well. I have seen this episode a few times now and it is a great watch.
