Britbox to Make 'Father Brown' Spin-Off 'The Sister Boniface Mysteries’

On paper, light-hearted period mystery series Father Brown might seem like the last property that would spawn a spin-off, particulary given that it's so distinctly tied to the books on which it is based and to its heartwarming lead character. But you'd be wrong. Because we're getting one. Prepare yourselves for The Sister Boniface Mysteries, coming soon to a Britbox app near you.

For those of you who don't remember, Sister Boniface only appeared in the very first season of Father Brown, but will return for ten episodes' worth of her own adventures. Original actress Lorna Watson will reprise her role as the sleuthing nun for Britbox.

The series will be set in rural Warwickshire furing the 1960s, and will follow the investigations of Sister Boniface, Bride of Christ, vintner, and Crime Scene Investigator. (Please tell me she gets that on a business card somehow.) In this time period, police forensics is...not that great. DNA testing hasn't exactly been discovered yet. Blood testing can take days. The notion of trace evidence is in its infancy and the preservation of crime scenes is shockingly hit and miss. Fortunately the Great Slaughter Constabulary has a secret weapon in its fight against crime.
