'Your book is the "really good book. Just one" that Roger Butler would have wanted' - Sir Ian McKellen

'Miraculous. The Light of Day reclaims a forgotten hero . . . I couldn't put it down' - Will Tosh

'Sir, we are homosexuals . . .'

So began the letter penned by Roger Butler and sent to several British newspaper editors - some of whom were so shocked they thought it was a hoax - in June 1960. Writing such a letter seven years before the decriminalisation of homosexuality was a radical and dangerous move. It was a risk that set a major milestone in the fight for gay rights - one that has been almost entirely forgotten.

This is the story of the first man to come out voluntarily, using his own name, to the entire British public, a decade before activists started petitioning gay people everywhere to 'come out proud'. Taking us through a criminalised underworld of gay pubs, parties and activist meetings, The Light of Day charts how Roger helped bring about the legalisation of homosexuality, but soon found himself marginalised from the movement he kickstarted after losing his sight in his early 30s.

Enter Christopher - a student asked to visit and read to an old, blind man at the beginning of a new century. As their intergenerational friendship bloomed, Roger came to trust Christopher with his most precious possession: memoirs of his revolutionary past, locked away in his home. After Roger's death, Christopher opened a series of unsent letters, left in a pink folder, addressed to him. They contained Roger's final wish, for Christopher finally to bring his remarkable, hidden story into the light of day.

'At times gripping, at times very personal, this remains an important piece of objective history, faithfully recorded and beautifully written' - Matthew Parris
