MAX KAMIEN IS LARGER THAN LIFE. I met him recently, and told him what a decisive influence his earlier book, The dark people of Bourke (1976), had on my first research. In Bourke, exploring the concept of a doctor acting as an agent of social change, the young Dr Kamien would always leave a calling card, so that patients or family would know he had been there. If no one was home, at least the visit showed that the doctor could be relied on to come. What could be simpler for the development of trust?
