The Divorce A Novel

There are two sides to every story. Which one will you believe?
Together for more than thirty years, Bea and Niklas live a comfortable life in Stockholm. But one evening, following a trivial argument, Niklas disappears. Weeks pass before it emerges that he has met someone else. To Bea's horror, he insists they must divorce.
But is this divorce really coming out of the blue? Is the person who does the leaving always the one at fault? What emerges once you begin scratching the surface?
