This is the dizzying story of Britain’s first two transsexuals and the unrequited love of one for the other. The title refers to Roberta Cowell, who as Bob Cowell had been a married father-of-two, fighter pilot and racing driver, until in 1948 he left his family and began life as a woman, causing a sensation when he sold his story to the Picture Post in 1954. But just as intriguing is the tale of his ardent admirer, Michael Dillon, who helped Roberta with her sex change. Michael began life as Laura, but after the war had what was, courtesy of a pioneering surgeon, the world’s first female-to-male sex change. His story did not end happily.
