Sister Boniface Mysteries (Seasons 1–4)

Sister Boniface Mysteries (2022) is a British detective series you can watch online on iFILM. The village of Great Slotter in 1960s England has an implausible murder rate and exactly one person the local police can rely on: a moped-riding Catholic nun with a forensic science doctorate.

Sister Boniface (Lorna Watson) handles crime scenes with a calm that leaves the official detectives looking at their shoes. She knows chemistry, toxicology, trace evidence — and she closes cases the constabulary has written off. The show spun out of the Father Brown universe and runs on the same cozy-English-village frequency, but with its own confident rhythm and a protagonist who earns her authority in a lab, not a pulpit.

A strong pick for viewers who want murder mysteries that don't wallow in grimness — clever, warmly eccentric, and anchored by a character you won't find anywhere else in the genre. Stream Sister Boniface Mysteries (2022) online on iFILM.
