The BritBox Original “Sister Boniface Mysteries” is a light-hearted murder mystery set deep in the British countryside, and stars Lorna Watson (Father Brown, Horrible Histories) as a clever, Vespa-driving, crime-solving Catholic nun.

The British period series also features familiar faces, including Mark Williams, that “Father Brown” fans will certainly recognize.

“Sister Boniface Mysteries” (2022) premieres February 8, 2022, with new episodes every Tuesday. Watch the trailer below, and stream the series through BritBox or here on Prime Video. BritBox has renewed the series for a second season, expected in early 2023.





In Season 1 of “Father Brown“, the BBC series about a local priest who often finds himself solving the town’s biggest crimes, two nuns are murdered. Father Brown investigates in the convent with the help of Sister Boniface (Lorna Watson), a young nun keen on detective fiction.

Now, Bride of Christ Sister Boniface is back as the head sleuth with her own cozy mystery series.

In a 10-episode series premiering February 2022 on BritBox North America, “Sister Boniface Mysteries” serves up light-hearted murder mysteries set in rural Warwickshire, England during the 1960s.

Sister Boniface is busy indulging her addiction to popular detective fiction and making wine at St Vincent’s Convent, but she’s about to become a secret weapon for the Great Slaughter Constabulary.

Boniface (in a role reprisal by Watson) is made the official Police Scientific Advisor. At a time when police forensics is rudimentary, Boniface’s I.Q. of 156, her PHD in forensic science and fully equipped crime laboratory make the nun a huge asset to the police.

Working alongside the dashing maverick and charming Detective Inspector Sam Gillespie, Sister Boniface uses advanced scientific techniques to track down killers.

DNA is yet to be discovered. 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. But if it’s a poison or the tiniest fiber or hair, Sister Boniface is on it. She’s more up to speed on the latest forensic techniques than the Police. Sister Boniface nun might be predisposed to forgive – but she’s also one heck of an amateur detective. 

Also by their sides: high-flying but buttoned-up Bermudian Detective Sergeant Felix Livingstone, who is left reeling by a cast of eccentric local characters and his boss’s reliance on a nun. Felix was supposed to be on secondment to the Metropolitan Police but an administrative error lands him in Great Slaughter. Although as Sam points out, that “Nun” ensures they have the highest clean-up rate in the county.

“Sister Boniface Mysteries” was commissioned by President and Founder, Soumya Sriraman for BritBox North America, who said that Lorna Watson caught his attention when the character Sister Boniface was first introduced in “Father Brown.”

Lorna Watson couldn’t “wait to get back in the habit and fight crime in “Sister Boniface Mysteries”!” Watson said her character is fun to play: “Quirky, funny, endearing and a total brain when it comes to forensics. In many ways she’s ahead of her time and I love her for that. It’s not every day you get to play a crime solving, Vespa driving nun.”

“Sister Boniface Mysteries” (2022) premieres February 8, 2022, with new episodes every Tuesday. Watch it on the BritBox website. or with the BritBox Prime Video Add-on Channel, here. Both offer free trials. Watch the trailer below.
