What kind of mystery does it hide behind these psychoanalysts' suicides: Tatiana Rosenthal, Viktor Tausk, Wilhelm Stekel, Herbert Silberer? Karin Stephen, a sister-in-law of Virginia Woolf, psychoanalyst herself, decides to follow the biographical tracks of these who all were authentically pioneers of the psychoanalysis, someone of them even very close to Sigmund Freud. During a stay at Zurich, Karin comes up against an unpublished manuscript, written by Otto Gross, an austrian psychoanalyst who was admitted several times into psychiatric asylums for drug addiction. Otto's papers seem to her to contain illuminating revelations about these losers of psychoanalysis, whose lives seem to be interlaced through exchanges of letters, poetries, journal fragments. But Otto's manuscript is litterary falsehood or authentic? Finally, Karin Stephen herself will die in the same way of her colleagues whose lives she dedicated herself: she committed suicide in 1953 in Britain.
