If we lived in the kind of country – and there are some – where people not only chose their presidents but chose as leaders poets, philosophers and novelists, a new novel by Brian Castro would be a sensation, even a political event. Students would be hawking pirated copies, queues would form outside bookshops, long debates would steam up the coffee shops, and the magazines would be full of it. Alas, China and Australia from the 1930s to the 1960s, where Castro takes us in memory, were not such places then any more than they are now.
