You have carefully concealed your true history.  Only your husband knew that you were an American prostitute when you met.  He bought out your contract and brought you back to England, but you soon became bored with each other, fighting constantly or descending into frosty silence.

In the absence of a decent marriage, you have become a stylish socialite who routinely sleeps with wealthy men.  Although it’s no longer a strictly-for-cash deal, you always see to it that you are well compensated for your efforts.
