Giggles, the Perfect Clown. The perfect Killer Clown that is! Nancy assures Kyra that they have nothing to worry about since Henry Howard Froam has been dead for years. But when their friend, Jacob, shows up unannounced and discovers that Henry Howard Froam left some items behind, Nancy realizes that the spirit of Giggles is determined to live on.
