Bateman, Kate. Her Majesty's rebels #2

"As a founding member of King & Co., London's most successful private investigation firm, studious Eleanor Law delights in secretly proving that women can solve crimes just as well as men. When a charming con man pretends to be her fictional boss, "Charles King," Ellie knows he's lying, but accepting the scoundrel's offer of help might just be the key to cracking her new case and recovering a priceless manuscript. "Henri Bonheur"--or "Harry" as he asks to be called--claims his criminal past is behind him, but a man who steals and seduces with such consummate ease can never be trusted. As the investigation draws them deeper into danger and desire, Ellie's infuriated to realize she's developed feelings for her law-breaking accomplice. How can she love the scoundrel when she doesn't even know his real name? And what will happen when Harry's past finally catches up with him?"--Amazon
