The discovery of a stolen red monoplane on the dry, flat bottom of Emu Lake meant many things for different folks. For Elizabeth Nettlefold, the chance to nurse its strangely ill meant renewed purpose in life. For Dr Knowles, brilliant physician and town drunk, it meant the revival of a romantic dream. For some it meant a murder plan gone awry, and for Bonaparte, it meant one of the toughest cases of his career. ’Bony – a unique figure among top-flight detectives.’ – BBC
