In January 1948, George Lucas, an unremarkable 21-year-old Roman Catholic who had just been demobbed from the Pay Corps, was living unhappily in Romford with his ill-matched parents, who relentlessly taunted him about his homosexuality. He would shortly get a job at the War Office and so embark on a lifetime’s career as a civil servant, commuting to central London every day to work at his desk and spend his evenings in search of sex and companionship, largely among the servicemen who hung around Marble Arch.
