When Netflix released The Keepers in May this year, we were all glued to our screens.
The true crime documentary revealed a crime that was so harrowing, so chilling – it followed you around for weeks afterwards.
The documentary tells the story of Sister Cathy, a nun who was murdered shortly after discovering a Catholic priest had been sexually abusing teenage girls at Archbishop Keough High School in Baltimore. Sister Cathy, a teacher at the school, promised to protect the girls – and within a few days she was murdered.
