'The Complete Father Brown Mysteries' includes 24 stories featuring G. K. Chesterton's eponymous Roman Catholic sleuth. These mysteries are the original source material for the current hit BBC TV show 'Father Brown' starring Mark Williams. Chesterton's priest-sleuth was loosely based on Father John O'Connor, a parish priest in Bradford, who was involved in Chesterton's conversion to Catholicism in 1922. By bringing murder and mayhem into the genteel setting of a village parish, Chesterton pioneered the 'cozy' mystery genre which Agatha Christie and others would further develop in subsequent decades.
