Mark Gatiss (Sherlock, Doctor Who, Game of Thrones) selects and introduces chilling tales by the unsung master of the classic ghost story - E.F. Benson. There's nothing sinister about a London bus. Nothing supernatural could occur on a busy Tube platform. There's nothing terrifying about a little caterpillar. And a telephone, what could be scary about that? Don't be frightened of the dark corners of your room. Don't be alarmed by a sudden, inexplicable chill. There's no need for a ticking clock, a limping footstep, or a knock at the door to start you trembling. There's nothing to be scared of. Nothing at all.
