Somebody is playing practical jokes at the Spook Squad's school and the Spook Squad are getting the blame! When a bucketful of cold water lands on the Head Teacher's head the girls swing into action. If they don't catch the culprits they'll be in hot water! But their problems really begin when they discover that the jokers are a couple of ghouls who think they're too cool for school! Roxy has a weird auntie. Her Auntie Rhee lives on Hangman's Hill in a spooky house called the Old Tower. The Old Tower looks like Dracula gave it a make-over. But Rhee isn't a vampire - she is a banshee. She's trying to protect humans from ghouls ghosts and long-legged beasties. But she can't do it on her own. That's why she needs the Spook Squad. The Spook Squad are Roxy Leena Nita and Emma and their poltergeist Rattle. These four girls are as bright and sparky as a fire in a fireworks factory. So on dark and stormy nights when the vampires are being a pain in the neck and hairy horrors are on the prowl the Spook Squad goes into action.
