This article sets out to explore the sublimations in the work of Agatha Christie, the resounding success of which is well known. In her very long autobiography, we see her trying to transform by all means available (play, writing, the impulse to investigate) a childhood that was marked by shortcomings, wounds and traumas, in response to which she wrote no less than sixty-six crime novels in which ordinary intra-familial evil is everywhere, and murder uppermost. Each time, Christie leads the reader into an exciting and thrilling investigation, solved by her famous detectives (Hercule Poirot and Miss Marple). Her pleasure in writing and her success as a writer did not, however, protect her from a serious clinical episode when, in 1926, she disappeared for eleven days, suffering from a moment of hysterical psychosis that was covered over by the silence of total amnesia.
