Welcome to Elbow Alley, home of the most monstrous mystery...
Pip was not expecting his new neighbours to be vampires, banshees and ghosts. Worst of all is the mysterious spirit snatcher, which appears out of nowhere and sucks away people's personalities. When it attacks Pip's parents, the only way to save them is to find and destroy it. But no one knows who it is...

Along with his new friend Fliss and her dog Splodge, Pip sets out to investigate, facing murderous ghouls, werewolf attacks and a dangerously mouldy cheese. Because if he and Fliss can't stop the creature by their thirteenth birthdays, they'll be spirit-snatched too.
