Season 10 Episode 15: I really enjoyed this one... I actually didn't notice George was missing until you mentioned it!
I like Detective Watts and this episode definitely made him more human. His sister was really cold.
I did feel a little badly for the murderess at the end. I had to look it up to remember she was an actress from "Bomb Girls".
It was fun to see Freddie working undercover in this one.
The subplot with the Inspector thinking he saw an affair was also amusing.
