The Haunted House of Horror1969

Horror Vault's take

A group of trendy young Londoners seeking thrills decides to explore an old, reputedly haunted mansion — and quickly discovers the terror inside is far more grounded than any ghost story. As members of the group begin turning up dead, paranoia sets in and no one can be trusted. With no way to know who among them is responsible, the survivors are forced into a desperate race to unmask the killer before the body count rises any further. Equal parts haunted-house chiller and whodunit, this late-sixties British shocker plays on the anxieties lurking beneath the swinging London façade.
