Light-hearted BBC murder mystery series starring a Vespa-driving, crime solving Catholic nun. From the makers of Father Brown and Shakespeare & Hathaway – Private Investigators.   It’s the 1960s and police forensics are rudimentary. Luckily the residents of Great Slaughter, nestled deep in the British countryside, have a secret weapon. Sister Boniface. This nun might be predisposed to forgive – but she’s also one hell of an amateur detective. If there’s evidence to be found, Boniface will find it, with a little help from dashing maverick DI Sam Gillespie and buttoned-up Bermudan DS Felix Livingstone, who’s horrified to be stuck in the eccentric world of Great Slaughter. A corpse is found stuffed inside a dummy at the local fair; tragedy hits a visiting TV crew; and a gruesome discovery is made in Edie’s beloved allotment plot. It’s down to Sister Boniface – and a few hasty Hail Marys – to save the day.
