I've recently been reading Glenn Chandler's book The Sins of Jack Saul (Second Edition) The true story of Dublin Jack and the Cleveland Street Scandal. (2016).
It's a good read about the two most explosive British scandals in the Late Victorian period, concerning male prostitution and male brothels (the Dublin Castle Scandal 1883-84 and the Cleveland Street Affair 1889-90) and a fashinating young rent boy who appeared in them both: Jack Saul, born in deep poverty in Dublin 29 October 1857 and passed away in tuberculosis 28 August 1904.
But Jack wasn't just a rent boy who had sex with horny lords, military officers and high ranking civil servants - he also wrote what could be called one of the first gay porn novels, The Sins of the Cities of the Plain, published in 1881.
