Ponder shut himself away for thirty years in an attempt to record every memory he ever had. Now he lies dead, surrounded by his magnum opus - The Catalogue - an exhaustive set of notebooks and journals that he hopes will form the map of one human mind. But before his friend Adam Last can call the police and inform them of Max's death, one rather gruesome task remains in order for Max's project to be complete. Interspersed with sections from The Catalogue, Adam tells the story of the man he knew - a man whose life changed dramatically the day he buried a dead labrador and fought a duel with his father.
