The circus returns to Kembleford and local waitress, Laura, is held to her promise given in jest the year before to marry the clown or hypnotist. The clown is cuddled naming the hypnotist; Laura's boyfriend, the clown's girlfriend, and his fellow clown are all suspected and Laura's willingness to marry the hypnotist puzzles Father Brown even though he agrees to marry the couple.
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.
