Meet Mr Bones, the canine hero of Paul Auster's remarkable novel. Bones is the sidekick of Willy G. Christmas, a brilliant but troubled poet-saint from Brooklyn. Together they sally forth across America to Baltimore, Maryland, on one last great adventure, searching for Willy's old teacher, Bea Swanson. Years have passed since Willy last saw his beloved mentor, who used to know him as William Gurevitch, son of Polish war refugees. But is Mrs Swanson still alive? And if not, what will prevent Willy from vanishing into that other world known as Timbuktu?
