He is determined to avoid marriage, she to despise men....
London 1818: Destitute, disillusioned, and desperate, Lady Rosalind Marlowe sets the tongues of Regency London wagging when she becomes the "Mayfair Thief". Targeting only those who had won large sums of money from her father, bleeding him dry and causing him to take his own life, she decides to teach them a lesson. She takes something valuable from each, leaving her calling card with a bible quote behind. On her last outing, she is caught red-handed.
Bored, restless, and guilt-ridden over the death of his own father and with his accusations of him being a selfish whelp still ringing in his ears, Lord Atherton heads off a Bow Street runner who is pursuing Rosalind. In an altruistic act, he engages her to be a companion to his mother, leading her to believe he is making amends for his father’s actions. Unaware that he has become the target of enmity from a desperate gambler from whom he has won a large sum of money, they are thrown into a series of increasingly dangerous situations.
Even as events conspire to draw them closer together, Rosalind discovers she has been hired under false pretences. Will they manage to overcome both pride and prejudice to finally find happiness, or will an unexpected letter from a solicitor drive a final wedge between them?
