No ghoul has a chance against the new ghosthunting agency - made up of schoolboy Tom, Hugo (the Averagely Spooky Ghost) and world-famous spookhunter Hetty Hyssop - or does it? Things hot up when they are called to the Seafront Hotel, where guests have gone missing and smoke and flames fill the fourth floor. Can the team extinguish the Gruesome Invincible Lightning Ghost, or are they toast?
