""...certainly a thought provoking read."
John Dyer, erstwhile journalist and now historical researcher and writer, has returned to the Oxford of his youth from South America. He has brought his son with him and he now attends the same prep school that Dyer did as a boy. The pair of them are taking time to settle, particularly the boy, Leandro, who comes up against the rough and tumble of young boys as well as more severe bullying. Many of the children at the school are from wealthy foreign families.
Dyer and Leandro find friendship with an Iranian boy at the school and his father, Rustum Marvar, a scientist working at the prestigious Cavendish laboratory. When Marvar makes an amazing breakthrough in his work, there is huge interest from both the Iranian authorities and various financial and political authorities who see power and wealth in developing from the innovation. But Marvar has been secretive and not told anyone about his discovery. When he disappears, he leaves a subtle clue for Dyer and lets him decide how to deal with the implications and aftermath of releasing the knowledge Marvar has found.
