Tony is a nine-year-old horror story addict, so he can hardly believe his luck when a little vampire called Rudolph lands on his windowsill one evening. Together the two have a series of hilarious adventures involving visits to Rudolph's home - The Vampire Family Vault - where Tony hears chilling tales of the cemetery keeper (the vampires' sworn enemy) and narrowly escapes the clutches of Rudolph's Great-Aunt Dorothy. The story reaches its climax at a disastrous supper party to which Tony has rashly invited the vampire and his sister, Anna, to meet his parents. The story, with its vampire protagonists, is known for its generous dose of offbeat humour.
