Sister Boniface Mysteries — what the crime series is about

The crimes in Sister Boniface Mysteries take place in the aptly named town of Great Slaughter, where the police rely heavily on help from their secret weapon, Sister Boniface (Lorna Watson). It's the 1960s so a time when police forensics is rudimentary, but wily Sister Boniface’s is at the forefront of this new field. With her PHD in chemistry, amazing IQ of 156, plus her knack for finding clues hidden in plain sight, she's a top sleuthing nun who knows the devil is in the details which makes her perfect for her role as official Police Scientific Advisor. 

Sister Boniface works alongside the maverick Detective Inspector Sam Gillespie (Max Brown) and Detective Sergeant Felix Livingstone (Jerry Iwu). Felix was supposed to be on secondment to the Met Police but an administrative error lands him in Great Slaughter. A cast of eccentric local characters combined with the local police's reliance on a nun leaves him reeling. But Detective Inspector Sam knows his superstar nun ensures the force has the highest clean-up rate in the county.

Interview: Lorna Watson on playing Sister Boniface

What attracted you to this show?
Lorna Watson says: "I haven’t played a comedic role before, so that was a massive attraction. Also, I haven’t read many scripts like this where I’ve laughed out loud. There are lots of detective series, but not many are as quirky as this!"

How would you describe Sam?
Lorna says: "He’s a bumbling bachelor. He’s got very strong ethics and he’s a war hero, but he relies heavily on Sister Boniface’s scientific expertise to close cases. She is the brain and Sam is the brawn!"

What’s his relationship with Sister Boniface like?
Lorna says: "They’re like brother and sister. He doesn’t fully understand everything that she exposes him to, but they like to have a drink together at the end of the day and just unwind."

Interview: Jerry Iwu on playing uptight copper DS Felix Livingston

Why did this drama appeal to you?
Jerry Iwu says: "It’s charming and endearing. I like shows like this that create a sense of community, because I come from a community like that in Ireland."

What’s your take on Felix?
Jerry says: "Felix has a heart of gold. He comes from a prestigious family in Bermuda, and there are a lot of great expectations for him. He looks at the Metropolitan Police in London as being at the forefront of modern policing, and wants to be around that.  The problem is, he is in the Cotswolds!"

How does he get on with Sister Boniface and Sam?
Jerry says: "There is a kinship between Felix and Sister Boniface, as he has a very keen interest in science. Sam’s like the wayward older brother who likes a drink and a party, whereas Felix is the studious one always doing the right thing."

Interview: Max Brown on his maverick police officer DI Sam Gillespie
