My Lady Thief by Emily Larkin

An elusive thief is haunting Regency London, stealing from the wealthy to give to the poor.
Arabella Knightley might be an earl's granddaughter, but behind her back she's known as Miss Smell o' Gutters. All she can do is endure London's barbs ... and dispense a little justice on the side.
Adam St. Just is one of England's most eligible bachelors, but his sister's first Season is teetering perilously close to disaster. Worse, his sister has struck up a friendship with Miss Knightley, the young lady whose prospects he inadvertently destroyed when he said she smelled of the gutters.
When London's altruistic thief comes to his sister's aid, Adam sets out to uncover the rogue's identity ... but what he discovers will turn his life upside down.
