Sister Boniface Mysteries Renewed for Third Season

BritBox International and UKTV’s Drama channel have commissioned a third season, including a feature-length Christmas special, of Sister Boniface Mysteries from BBC Studios.

Lorna Watson will return as Vespa-driving, crime-solving Catholic nun Sister Boniface. During the new season, she will find herself stranded on a train during Britain’s worst winter on record. When a precious jewel is stolen from its safe and a passenger is discovered murdered, she will have to use her skills to find who is responsible.

Elsewhere in the series, a famous organist is murdered in the chapel, Great Slaughter’s first-sci convention results in a mysterious kidnapping and a “dead cert” at the screen tests for the new Agent Best ends up dead. Additionally, Felix’s fiancée Victoria arrives from Bermuda with an ultimatum.

Guest cast for the third season includes Rupert Vansittart (Game of Thrones, Gentleman Jack), Siobhan Redmond (Queens of Mystery, Two Doors Down) and Timothy West (Last Tango in Halifax, Gentleman Jack).

Sister Boniface Mysteries is a BBC Studios Continuing Drama co-production for BritBox International and UKTV’s Drama channel and streaming service UKTV Play. BritBox will also premiere the series in South Africa, Australia, Denmark, Sweden, Norway and Finland. The series producer is Mat McHale, with executive producers Neil Irvine for BBC Studios and Reemah Sakaan and Stephen Nye for BritBox International.

The feature-length Christmas special will be written by series creator Jude Tindall and directed by Ian Barber.

“Over the last two series, Sister Boniface Mysteries has developed an enthusiastic and dedicated following both in the U.K. and internationally, so we’re delighted to be bringing her back for a third series,” Irvine s aid. “Lorna Watson will return with fan favorites DI Sam Gillespie (Max Brown), DS Felix Livingstone (Jerry Iwu) and WPC Peggy Button (Ami Metcalf) also starring. One thing’s for sure: if there’s evidence to be found, Sister Boniface will find it.”

Watson said, “Playing Sister Boniface is a dream, as is filming in the Cotswolds, so I’m thrilled to be back for another series. I can’t wait to get the team back together, jump on the Vespa and see what crimes there are to solve in series three!”

“Right from her first appearance on screen alongside Father Brown, the character of Sister Boniface has delighted fans, and Sister Boniface Mysteries has gone from strength to strength, building an international fanbase on BritBox in our markets and being the gold standard for charming British crime drama,” commented Sakaan, who is CEO of BritBox International. “We and BBC Studios originally developed this series as a spin-off, and we are proud to see its continued success and growth.”

Emma Ayech, channel director for Drama at UKTV, added, “We are so excited to see our brilliant Vespa-riding nun return for more crime solving. The series has been one of our highest rating shows for 2023, so it’s fantastic to be giving our audience the gift of a brand-new, feature-length episode this Christmas.”
