The Perfect Crimes of Marian Hayes by Cat Sebastian

Cat Sebastian returns to Georgian London with a stunning tale of a reluctant criminal and the thief who cannot help but love her.

Marian Hayes, the Duchess of Clare, just shot her husband. Of course, the evil, murderous man deserved what was coming to him, but now she must flee to the countryside. Unfortunately, the only person she can ask for help is the charismatic criminal who is blackmailing her—and who she may have left tied up a few hours before…
A highwayman, con artist, and all-around cheerful villain, Rob Brooks is no stranger to the wrong side of the law or the right side of anybody’s bed. He never meant to fall for the woman whose secrets he promised to keep for the low price of five hundred pounds, but how could he resist someone who led him on a merry chase all over London, left him tied up in a seedy inn, and then arrived covered in her husband’s blood and in desperate need of his help?
As they flee across the country—stopping to pick pockets, drink to excess, and rescue invalid cats—they discover more true joy and peace than either has felt in ages. But when the truth of Rob’s past catches up to him, they must decide if they are willing to reshape their lives in order to forge a future together.
