Hop on your bicycle and travel back to the 1950's to join priestly gumshoe Father Brown (Mark Williams, Harry Potter, Doctor Who) for another compelling series of mysteries based on the novels of G.K. Chesterton. Quiet lanes and country houses hold daunting secrets that only Father Brown, using his intuition and skill, will be able to work out - much to the chagrin of Inspector Sullivan (Tom Chambers, Waterloo Road). Joined by his gang of dedicated helpers: the excitable parish secretary Mrs. McCarthy (Sorcha Cusack, Merlin, Silent Witness), the glamorous Lady Felicia Montague (Nancy Carroll, Call the Midwife, Inspector Lewis) and her resourceful chauffeur (and mostly former small-time crook) Sid Carter (Alex Price, Being Human, Merlin), Father Brown faces some of his most daunting cases yet.
