The Unmasking of a Lady (Mills & Boon Historical Romance)

It's common knowledge that Lady Arabella Knightley spent her early years in London's gutters. But what the Ton doesn't know is that, while she dances prettily by day, by night she helps the poor—stealing jewels from those who court her for her money but disdain her for her past....
Bored by polite society, Adam St. Just determines to expose the thief. Upon discovering it's Arabella, he should be appalled. Instead, captivated by her beauty, his proposal is simple—he'll unbutton Lady Arabella...or unmask her!
