Father Brown is based on G. K. Chesterton's detective stories about a Catholic priest who doubles as an amateur detective in order to try and solve mysteries.

Set in the 1950s, this prequel to Keeping Up Appearances looks at the life, relationships, and aspirations of 18-year-old Hyacinth. Long before she becomes Mrs. Bucket (pronounced Bouquet), young Hyacinth is already dreaming of matching china and a bedroom in pastel shades. If only her family were more like the upper-class Cooper-Smiths in whose home Hyacinth works as a maid.
