The aim of this bachelor's thesis is to submit the character of Grey in Mo Hayder's novel, The Devil of Nanking to a Freudian reading with focus on repression and trauma and their impact on sexual development and obsessive behavior. The analysis of to what extent Grey's past and present experiences form the cornerstone to her mental and sexual development including repression and obsession will be based on Sigmund Freud's psychoanalytic theories. The claim is that Grey's obsessiveness and sexuality can be explained and seen in terms of a Freudian view of trauma resulting in repression.
