It's about Murray and Bun who go through an enchanted cat flap and end up in a haunted house trying to catch a ghost called Morris for Lady Daphne and her husband Geoffrey Hogchester - it's their spookiest mission yet! Our Primary 5 reviewer liked when Murray thought he caught a ghost but he caught a hanky!! The next time a person called Cyril who had a stomach ache by eating too many marshmallows. And then the next time another person called Dottie Dazzle was stuck with candy floss! She also liked when Murray said Morris was a hanky, a musty old bed sheet and a baggy vest! And also the Buns bonus bits.
