A forgotten writer who was once a Stasi agent and who provoked the world with his books was trying to find peace and quite by buying an old farm in a mid sized city in southern France so at least it seemed to everyone, but the reality told a different story and Francine Autem who sold him the farm through her little agency was suddendly confronted with many strange and unregular occurences which involved her in a world of sinister and life threatening secrets and a journey began that changed hers and other people`s life completely. Who was this man and why did their path cross?
