The Sussex Fretsaw Massacre

It's Halloween night and anxious, inexperienced Olly Wilson has been hired to drive five obnoxious people to a political party conference, but is hopelessly lost.

 Meanwhile, in a nearby manor house in the middle of nowhere, human-passing eldritch horror Ricky Porter wants to see his own future, but the ritual involves human sacrifice. The omens tell him five unfortunate souls are doomed to die before midnight - but his living, sentient house (and queerplatonic partner) just wants a quiet night watching films and bans him from taking their deaths into his own hands.

 When Olly and his five passengers show up on the doorstep unexpectedly after some car trouble, bodies are already doomed to hit the floor - and Olly's life is about to change forever.
