Who is Jay G. Capsa, this young and talented writer presented by his publisher as the latest literary sensation? A lost boy who has attained the sublime through his writing or an impostor? The answer will turn out to be even more surprising. A much older man, a teacher at the Henri IV High School and a frustrated writer, holds the keys to this mystery. From Eastern Europe to the outskirts of Paris, via the high society world of the leading publishing firms, “Tant de nuits” paints the portrait of one of the greatest literary impostures and is inspired by the J.T Leroy affair.
