Strange things start to happen when Mr Dark's Pandemonium Carnival arrives in Greentown.

An Indian summer, 1942: "When I was thirteen, all I wanted to be was a hero." A young evacuee's response to the surrounding war-obsessed adult world seems the only one available to him, until he forms 'a particular friendship' with another boy, a Jewish refugee. This threatens the stability of his gang (who also mirror the racist/jingoist attitudes of adulthood), and he is caught in Forster's great liberal crux: your country or your friend?
