It’s a lovely summer day. Max and Maggie decide to go and visit the castle on the hill near the town. Everybody says it’s a haunted castle but Maggie doesn’t believe it. Max thinks that castles are perfect homes for ghosts and he is not sure that he wants to go. When they are in the castle lots of strange things happen! First it’s only Max who sees funny faces and people moving in the pictures on the walls but then Maggie starts feeling a bit worried, too.
