A Vampire in the Neighborhood

The new girl is called Helga Nuegenstorm and she looks really strange and behaves oddly (e.g., she had black ringlets of hair, wears old fashioned clothes, pale skin and has gray eyes). Thus she is the perfect candidate for the monster they believe she was. The narrator Maddy Simon tries to test her by inviting Helga to sit down with her friends- Carrie, Yvonne, and Joey, but she replies: "I don't eat." This confirms their suspicions and they decide to investigate more information about her... So they go to her house and look in the bedroom window. In the end it turns out Helga isn't a vampire, but as the expected Goosebumps twist, the other kids are!
