Horror House: Mary Hooper's Haunted (Unabridged‪)‬

A new couple have moved into Hardstone House, and it's just Jake's luck that instead of a cool, footballing grandson they have a granddaughter called Claire, who likes tap dancing and tea parties.

But then Claire tells Jake and Jenna that Hardstone House was once a school, with a cruel and heartless headmaster, and she reckons it's haunted. But by whom? And why?
