Six days ago, a man blew himself up by the side of a road in northern Wisconsin . . .
The explosion that detonates the narrative of Paul Auster´s remarkable novel also ends the life of its hero, Benjamin Sachs, and brings two FBI agents to the home of one of Sachs´s oldest friends, the writer Peter Aaron. What follows is Aaron´s story, an intricate, subtle and gripping investigation of another man´s life in all its richness and complexity.
