Locked in a soundproof basement with nothing but — you guessed it — a black phone, Finney must use the only weapon he has: the ghostly advice of The Grabber’s previous victims. If you fancy reading the story, it’s included in 20th Century Ghosts by Joe Hill, alongside 14 other short stories. (I watched this movie without having read the story first. I’ll return my bookworm card in shame now.)
