Everyone had gone to school with someone’s brother or known each other up at Cambridge. These were serious young leftist intellectuals, many of them communists devoted to the idea of a classless society, but they were also upper class and English and so almost unconsciously sought out others of their kind and mixed with them, while the working-class youth stood alone just outside the perimeter of this charmed circle, coming as close as he dared, barred from entry by an invisible boundary of accent.
