Production on the third season of BBC's comedy murder mystery series Sister Boniface, is underway in Oxfordshire, UK.

Filming commenced earlier in June, and crew have recently been spotted on location in the county per pictures published by Oxford Mail.

The series is a cosy detective drama following the investigations of Sister Boniface of St Vincent's Convent.

In June it was announced Lorna Watson is returning as the crime solving Catholic nun, with a guest cast including Rupert Vansittart (Game of Thrones, Gentleman Jack), Siobhan Redmond (Queens of Mystery, Two Doors Down) and Timothy West (Last Tango in Halifax, Gentleman Jack).

The Season 3 summary reads: "Britain is in the grips of the ‘Big Freeze’ – the worst winter on record. Sister Boniface and her fellow travellers are stranded in a train after a frozen coupling snaps, leaving the last carriages stranded in snow. When The Star of the Orient, a precious jewel, is stolen from its safe and a passenger is discovered murdered, Sister Boniface must use her exceptional detection skills to decide who among the suspects is responsible. But with little signs of rescue and a failing generator, passengers must also contend with a more pressing issue – freezing to death.

"Elsewhere in the series a famous organist is murdered mid-tune in the chapel, Great Slaughter’s first sci-fi convention results in a mysterious kidnapping and a ‘dead cert’ at the screen tests for the new ‘Agent Best’ ends up, well… dead.  To top it all, Felix has a challenge of his own when his fiancée Victoria arrives from Bermuda with an ultimatum which could change everything…"

Series 3 is a co-production for Britbox International and UKTV’s Drama channel and will include a feature length Christmas special written by series creator Jude Tindall and directed by Ian Barber.

In a statement, Watson said of her character: “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!”

Neil Irvine, executive producer at BBC Studios added: “Over the last two series Sister Boniface Mysteries has developed an enthusiastic and dedicated following both in the UK and internationally so we’re delighted to be bringing her back for a third series. Lorna Watson will return with fan favourites 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.”

Sister Boniface Mysteries is a BBC Studios Continuing Drama Co-Production for BritBox International and UKTV’s Drama channel and streaming service, UKTV Play.
