The police officer is too stupid.
I've started watching series 5, and I'm increasingly bothered by how stupid the ott lead police officer is (I forget his name.)
I get that it's a running theme that one or more of the police are idiots, and that the sleuth has to work it out. But, god, the police officer in this is so stupid.
I feel like the episodes are basically like this:
*Cop sees dead man on the floor outside a house with a ladder beside him*
Cop: well clearly he fell from the ladder after trying to clean his roof.
Father Brown: But this isn't actually his house. Also there's a bullet hole in his head.
*Police guy looks around and sees a gardener watching.
Cop: well clearly it was that man!
*Promptly arrests innocent bystander and Father Brown has to discover the real murderer before some innocent is hanged.*
