“Collision” was quite good and Midsomer Murders is entertaining though hard to believe so many townspeople could get offed in such a small and beautiful part of England.
I always tried to guess how many murders would actually be committed/solved in a Midsomer episode - since it was seldom just one. As for the DC or Detroit level murder rate and the resulting depopulation, I was more concerned about Cabot Cove than Midsomer.
