Production is well underway on a fourth series of the popular series Sister Boniface Mysteries. The spin-off to the long-running BBC Studios mystery drama Father Brown sees Lorna Watson as crime-solving Sister Boniface in the fictional town of Great Slaughter in the Cotswolds.

The cosy mystery drama recently aired its third series on Drama channel and BritBox with filming now ongoing for the fourth series as well as a feature-length Christmas special. Lorna Watson says: “It’s brilliant to be back with the gang for series four. I feel very lucky to be part of such a lovely show and can’t wait to get cracking, solving crime in the Cotswolds sunshine.”

Here is what we know so far about the new Christmas special and series 4, including possible release dates and cast.

The official plot synopsis for the upcoming Christmas special reads: "Returning by popular demand, this year’s feature-length festive special features the Great Slaughter Amateur Dramatics Society (GSADS) pantomime.

"This year it’s Cinderella and with the appointment of a celebrity director the pressure is on to deliver their biggest and best performance yet. Rehearsals commence but soon cast members start dropping like flies.

“Can Sister Boniface catch the killer before they strike again? Will GSADS give the public the festive theatrical treat they deserve? And, most importantly, can Sam and Felix pull off a polka in a pantomime horse?”

Focusing on series 4, the synopsis reads: "Elsewhere in the series a bucking bronco goes haywire on the set of a game show, a killer scarecrow stalks the streets of Great Slaughter, the Scottish invade, a femme fatale drops to her death in a stunt gone wrong and to top it all CC Lowsley (Robert Dawes) has arranged something called “team building”.

"Meanwhile Reverend Mother Adrian (Carolyn Pickles) is keeping a secret, one that could tear the Sisters lives apart as they know it…"

The Christmas special will likely be broadcast over the festive period later this year. The 2023 special aired on December 19, 2023, which could give some indication of when this year’s special will be broadcast.

It could be a little while longer for series 4 judging from when the third series was broadcast. The third series was broadcast in June and July this year which could mean we should expect the latest episodes to air around this time or before.

Who is in the cast of Sister Boniface Mysteries?

Lorna Watson is back as TV’s number one Vespa driving, crime-solving, Catholic nun alongside Max Brown as DI Sam Gillespie, Jerry Iwu as DS Felix Livingstone and Ami Metcalf as WPC Peggy Button.
