This month World Book Club talks to British writer Sarah Waters about her chart-topping novel, Tipping the Velvet.

Celebrating twenty years since its first publication Tipping the Velvet is a bawdy, historical, lesbian romance, following the startling career of Nan King, oyster girl from Whitstable turned music-hall star turned rent boy. Star-struck and infatuated with actress Kitty Butler Nan starts up a double act with her idol both on and off the stage. But when Kitty, hankering after a more conventional life, spurns Nan in favour of marriage to her manager, a devastated Nan is propelled into a series of ever more erotic excursions and ultimately a struggle for survival.
