When we were orphans

Christopher Banks, the protagonist of Kazuo Ishiguro's fifth novel, When We Were Orphans, has dedicated his life to detective work but behind his successes lies one unsolved mystery: the disappearance of his parents when he was a small boy living in the International Settlement in Shanghai. Moving between England and China in the inter-war period, the book, encompassing the turbulence and political anxieties of the time and the crumbling certainties of a Britain deeply involved in the opium trade in the East, centres on Banks's idealistic need to make sense of the world through the small victories of detection and his need to understand finally what happened to his mother and father.
