Opened in a flashback style, beautiful and tempting, the biography of Mary Anne Clarke, the notorious heroine, unfolded. Ms. Du Maurier weaved a story of a woman's power struggle and web of intrigue played in society dominated by men. Set in London at the time when Paris was being ruled in Terror regime, London was in parliamentary turmoil and both countries are in war at the end of 18th century.

Mary Anne, with her cunning wit and unbeatable Irish blood, was born in a London slum neighbourhood. With her resourceful mind, she determined to be a success in men's world by playing the same game, with the same rules. She first tried to find a wealthy husband but got a big-mouthed, good-for-nothing one instead. Not to be beaten by circumstances, she left her husband and started to use her unique beauty to make connection, to be a 'social climber', in order to provide food and shelter for her 3 children, a mother, a half-sister and a brother. As time would have it, she was introduced to The Duke of York, became his mistress and the scandalous dealings began.

Being a mistress to a prince didn't mean she would have unlimited income. On the contrary, to maintain the house, lifestyle and servants, she must do 'side jobs' by promoting soldiers to the Duke with some amount of fee. This would lead to the most scandalous trials in England concerning the royal family.
