Why wish to talk about her research and, above all, have the desire to transmit it through a novel and, furthermore, a crime novel? What were the challenges encountered both in terms of research and fictional narrative, and, in contrast, what were the benefits of this other form of writing? These are the questions that this essay intends to answer by exploring the intersection of scientific research in law and sociology of law with fiction literature when these two discourses are struggling with a subject which is disturbing by nature, magnitude and severity such as the extreme of genocidal violence. The contribution of this article to further reflection lies essentially in the “inside” approach to the problem, as the author has herself embarked on this writing adventure through a novel, largely nourished by her own research, published under the title Un Silence de pierre et de cendre. In doing so, this essay is part of the growing field of interdisciplinary studies combining the field of letters with sociology, history, law, etc., putting literature at the heart of the flow of ideas.
