'Sister Boniface Mysteries' Season 4 Will Premiere on BritBox This August

Everyone's favorite crime-solving nun is headed back to our screens just in time to close out summer. The highly anticipated fourth season of Sister Boniface Mysteries is officially set to premiere on BritBox this August, an announcement that will likely come as a relief to fans who've been waiting (im)patiently for news of their favorite Vespa-riding nun since the series' Christmas special aired at the end of last year (which focused on the annual Great Slaughter holiday panto and if you haven't seen it, please fix your life immediately). 

The popular 1960s-set detective dramedy follows the adventures of Lorna Watson's eponymous Sister Boniface, a character who got her start on the long-running series Father Brown. She's a Vespa-riding Catholic nun who uses her fully stocked crime lab and love of detective fiction to moonlight as a forensic scientist in her spare time. (Because as anyone who watches any sort of British procedural already knows, in this genre, literally anyone can become a competent and succesful crime solver.)

Season 4 will once again be comprised of eight episodes. We've reached the mid-1960s at this point and our favorite nun's new adventures will encompass everything from a bucking bronco that goes haywire on the set of a game show to a killer scarecrow that stalks the streets of Great Slaughter, and CC Lowsley's (Robert Dawes) decision to engage group team-building exercises with the local police force.

"Sister Boniface Mysteries is a BritBox staple, and we look forward to sharing a new season of crimes, capers, and Sixties shenanigans with our eager audience.” Robert Schildhouse, President BritBox North America & General Manager BritBox International said when the fourth season was announced.

Here's the Season 4 synopsis. 

The nun who is the police’s secret weapon is back. Crime solving is her habit! The wine-making, moped-riding nun investigates more ugly deeds in beautiful surroundings. It’s the mid-1960s in the quaint Cotswold village of Great Slaughter, but strange things are afoot. A killer scarecrow stalks the streets, all the women call a general strike and the police embark on something called “team building”. Sister Boniface is looking forward to a wholesome weekend away with the sisters, only to be confronted with yet another murder.

Alongside Watson, the series' returning cast members include Max Brown (The Tudors) as DI Sam Gillespie, Jerry Iwu (Sex Education) as DS Felix Livingstone, Ami Metcalf (Silent Witness) as WPC Peggy Button, and Carolyn Pickles (Broadchurch) as Rev Mother Adrian. The Season 4 guest cast includes Les Dennis (The Madame Blanc Mysteries), Katherine Kingsley (The Larkins), Martyn Ellis (Renegade Nell), Mina Anwar (Happy Valley), Ed Birch (The Witcher), and Daniel Laurie (Call the Midwife).

Series creator Jack Tindall wrote the new season, with Paul Gibson directing and Dawn Coulson-Beckett as Script Producer. Executive producers include Neil Irvine for BBC Studios, Schildhouse and Stephen Nye for BritBox International, and Claire Hookway for UKTV.

Sister Boniface Mysteries Season 4 will premiere on August 19, with weekly releases to follow through October 7. Seasons 1-3 are currently streaming on BritBox, as well as airing on select local television stations. Check your local listings.
