Groosham Grange: A Full-Cast BBC Radio Dramatisation

Monsters, witches and wizards are rife in this full-cast adaptation of the spooky fantasy adventure from Anthony Horowitz

When twelve-year-old David Eliot is expelled from his exclusive boarding school, Belton College, his parents are furious. A surprise invitation from a new school arrives in mysterious circumstances the very next day and young David find himself enrolled into Groosham Grange, a school that is strict on disciple, much to the delight of his irate father.

But things aren’t quite as they seem. After David is rowed across the lake to Skrull Island by Captain Bloodbath, along with new-found classmates Jill and Jeffrey, things go from strange to stranger and David is worried… The children must sign the register in their own blood and they begin to suspect Mr Kilgraw, the deputy head, might be a vampire. They soon discover that the headteacher is actually the ‘heads’ teachers – two heads, one body – and that the English teacher is mostly held together by bandages. The other students are hiding something, and when kids start disappearing without a trace in the middle of the night, David and Jill don’t know where to turn…
