What is the author's style in The Hunchback of Notre Dame by Victor Hugo?

Typically, a gothic novel includes a dark setting preferably in an old castle; tension created through suspense; the appearance of mysterious signs that act as warnings or prophecy; the stirring of strong emotions; and of course a threatened woman in need of rescue. Hugo's The Hunchback of Notre Dame contains all of these elements and more. First there is the gothic cathedral of Notre Dame with its castle-like structure and embellishments of gargoyles, dark shadowy staircases, towers, and hidden rooms. This setting emphasizes mystery and foreboding. Then there is the constant flow of emotions, including despair, brief happiness, surprise, shock, disappointment, and fear. Finally there is La Esmeralda, the beautiful woman in distress.
