|summary=England 1645: Matthew Hopkins is good at his chosen career: seeking, testing and convicting those with the Devil in them. His sister, Alice, doesn't realise the full connotations of his actions until, widowed and pregnant, she returns home. Alice is grateful to be allowed to live under Matthew's roof but then watches his sinister finger of suspicion point in unexpected places. This is a man changed from the boy that Alice used to know. She never then realised that he'd be capable of killing hundreds of people and making her the Witchfinder's Sister.
