The "Liaisons" episode is one of the best. It's kind of like 8MM, but with Davies investigating a snuff film rather than the insane Nicolas Cage. It's one of the darker ones. Unlike "Funny Thing", you get some sense of relief at the end.

The "Montevideo" episode is the second best of the set as it is decidedly creepy, especially given that the cab driver went from being a crabby-looking old man to a relatively younger man who acted and looked like a millionaire. The conclusion was a bit head-scratching in the reason department — but still a good episode nonetheless.

The "Dead Peasants" episode was a bit on the weak side with the plot. The whole business of a secret group engaging in insurance fraud was cool, but it seemed to fix too much on the person who was murdered as opposed to the actual fraud itself. Maybe I read the episode wrong — it just seemed misguided.

The interplay between his boss and co-workers (Rob Spendlove, Charles De'Ath, Billy Geragthy) is less caustic in this new season. The writers might have felt that it would be old hat if Davies kept fighting back and forth with them. There's even a bit of irony put into these stories now and then. One scene I found hilarious was when his co-workers and boss go on a bust and find themselves fooled (it involved department store dummies). You would have to watch it to get the idea.

Series 4 could very well be the final series of The Last Detective. Still, this box set is worth every penny simply to watch a fresh take on a tired genre.

If you still long for more Peter Davison, go grab some Netflix rentals of his time as Doctor Who. If you happen to have a mate in the UK or poke around YouTube sometime, you might find his 10-minute reappearance in the newest Doctor Who titled "Time Crash".
