A lost musical masterpiece is at the heart of this gripping intellectual mystery by award-winning writer Andrew Crumey. In 1913 composer Pierre Klauer envisages marriage to his sweetheart and fame for his new work, 'The Secret Knowledge'. Then tragedy strikes. A century later, concert pianist David Conroy hopes the rediscovered score might revive his own flagging career. Music, history, politics and philosophy become intertwined in a multi-layered story that spans a century. Revolutionary agitators, Holocaust refugees and sixties' student protesters are counterpointed with artists and entrepreneurs in our own age of austerity. All play their part in revealing the shocking truth that Conroy must finally face the real meaning of "The Secret Knowledge". A novel for readers who like intellectual game-playing and having their imagination stretched.
