In this non-fiction novel – road trip, confession, and erotic tour de force – Emmanuel Carrère pursues two consuming obsessions: the disappearance of his grandfather amid suspicions that he was a Nazi collaborator in the Second World War; and a violently passionate affair with a woman that he loves but which ends in destruction. Moving between Paris and Kotelnich, a grisly post-Soviet town, Carrère weaves his story into a travelogue of a journey inward, travelling fearlessly into the depths of his tortured psyche.
