On the way to the police with the proof, Caroline is tricked into coming to grim Bat House. Expecting refuge, she suddenly finds herself in even greater danger. For the mistress of Bat House is Miss Moore's sister, a socially ambitious fanatic determined to do anything to save her family's reputation - even sacrificing Caroline's life.
