In this research work, we propose to analyze the theme of amnesic disorders, experienced by the main character, Anna Heymes, in the crime novel “The Empire of wolves” by Jean- Christophe Grangé. For this, we will use Lacan's psychoanalysis, using key concepts such as the subject of the unconscious, the imaginary, the real and the symbolic. These will allow us to study the dreamlike universe of the protagonist, wife of a senior Parisian official – who is haunted by frightening visions and is in search of her identity – but also to explore in depth the recesses of her memory.
