'Unlike an autobiography, which tends to be time-bound and inclusive, the memoir can wander at will in the writer’s past, searching out and shaping an idea of self.

The memoir shows how Blainey set his own course as a historian and forecasts the brilliant but sometimes unexpected career that he achieved.' (Introduction)
