A Lady’s Luck by Maggie Dallen

Henri lives to uncover secrets, but this man has everything to hide…
Lady Henrietta Bloomfield has built a fortune gambling on the utterly predictable foibles of her peers. When her latest wager fails thanks to the stodgy Earl of Colefax and his surprisingly rash behavior, she’s more intrigued than disappointed. It seems there’s more to the upright earl than meets the eye, and Henri makes it her mission to discover who he really is. The more she gets to know the real Alistair, with his dark passion and his mysterious missions, the more she finds him utterly, irresistibly appealing. And what she feels when he holds her in his arms? That’s enough to make her doubt her sanity. No rational woman should lose her heart to a man who’s determined to ruin her fun.
Alistair might have found Henri’s nosey antics amusing…if he didn’t have so many secrets to hide. But it’s not just his pride on the line–lives are at stake, including his brother’s. He has no choice but to do whatever it takes to distract Henri from her suspicions, and if kisses are the best way to do that, then so be it. Now if only he can kiss her senseless without risking his own heart in the process.
