Father Brown: "The Fool's Crown"

This is the third in chronological sequence of five "Father Brown" spec scripts I have written for the BBC comedy-drama series (I'm working on the fifth one now); Though each have separate stories, certain story elements/character arc developments continue through each one to the next (as well as having callback references to actual produced episodes of the series). Even if you only read one of them, I've included a "Previously On" summary of what's happened so far in my previous specs for the show ("The Dark Lantern" and "The Wrong Scone") right after the character list at the top of the script, which should make the story understandable even for readers/viewers who are not familiar with the show itself. I also use the UK spellings of various words, which differ from the US spellings, since these specs are aimed at selling to the UK market/BBC, with the hope of getting the attention of the producers of the "Father Brown" series itself, since my ultimate goal as a writer is to become a regular contributing writer to this series.
