Father Brown is a Roman Catholic priest who uses intuition and understanding of human behavior to solve crimes, usually murders in the small community around his parish.
He uses the fact that he doesn’t really seem like the typical detective to his advantage and has a rather soft demeanor.
Father Brown first appeared in G.K Chesterton’s 1910 story “The Blue Cross” and went on to be a prominent character in pop culture well into modern times, in no small part due to the successful 2013 BBC TV series.
He has been cited as the inspiration for another unassuming detective character with a soft personality, that being Detective Columbo. Who sadly is not public domain but Father Brown can fill the same role rather well.
