Our Introduction traces the biography of John Cleland, the notorious and hitherto elusive eighteenth-century author, as we now see it through the letters and documents published in this volume. We follow his early career in Bombay, climbing the ranks of the East India Company, his prison writing of and subsequent re-arrest for Memoirs of a Woman of Pleasure, his volatile relationship with his mother, his disappointment in writing for the stage, his patronage by the Delaval family, and – new to Cleland scholarship – his intriguing friendship with Jeanne-Marie Leprince de Beaumont and the French spy Thomas Pichon, which reveals new attributions to Cleland and his attempted assimilation amongst a literary Francophone community as ‘Jean de Cleland’.
