Crooked House S01E03 - The Knocker

Back in the present day, commitment-shy Ben begins to discover that, though demolished, Geap Manor casts a long shadow. Having recently left his girlfriend Hannah for a life of excitement over cosy domesticity, he is excited by the curator's stories and screws the ancient door knocker to his new front door. However, he soon finds himself getting more excitement than he bargained for as the past begins to intrude rudely with a loud knock at the door in the night and a terrifying journey into Geap Manor's bloody past.
