The Witch's Bathroom

Casey had often referred to it as the witch's bathroom. But that was just tongue in cheek. Her mother had always been a bit of an eccentric decorator and Casey didn't think for a moment that there was anything in it. But little did she know how much evil really lurked within the walls of that small room... not until that fateful day when she looked up and found herself face to face with a ghost.

Why on earth would a ghost be haunting their bathroom? Why is it trying to scare her? Casey couldn't possibly imagine but she needs to find out.
