Anisha, Accidental Detective: Fright Night

There's a spooky mystery at school, in the sixth hilarious case in the award-winning Anisha, Accidental Detective series!
It's Halloween and everyone is excited about the school disco. It's a bit much for me - all that dressing-up and dancing. I'd rather cosy up with a good book, but Milo, Mindy and Manny are all super excited.
Or at least, they were excited, until all these strange things started happening - messages appearing on the whiteboard, lights flickering on and off, books flying off the library shelves... Some of the other kids have been whispering that the school is haunted, but Mr Graft says that if the spooky mischief doesn't stop, then the disco will be cancelled.
Look's like a mission for me, Anisha, accidental ghost detective!
