What is the truth? In this blistering story of a ghostwriter haunted by his demonic subject, the Man Booker Prize winner turns to lies, crime and literature with devastating effect Kif Kehlmann, a young penniless writer, is rung in the middle of the night by the notorious con man and corporate criminal, Siegfried Heidl. About to go to trial for defrauding the banks of $700 million, Heidl offers Kehlmann the job of ghost-writing his memoir. He has six weeks to write the book, for which he'll be paid $10,000. But as the writing gets under way, Kehlmann begins to fear that he is being corrupted by Heidl. As the deadline draws closer, he becomes ever more unsure if he is ghost writing a memoir, or if Heidl is rewriting him - his life, his future. Everything that was certain grows uncertain as he begins to wonder: who is Siegfried Heidl — and who is Kif Kehlmann? As time runs out, one question looms above all others: what is the truth? By turns compelling, comic, and chilling, this is a haunting journey into the heart of our age.
