The Traitor's Club Series by Laura Landon

Hugh Wythers was a man of great promise, but none would know it. Recently returned from the Crimea, he found his only delight in the midnight playgrounds of London. And why not? War had taught him to live every day to the fullest. And then his father cut off his funds. Reeling from the predicament in which he found himself, he fell head over arse—literally—into the arms of the perfect wife. The homely, unmarriageable Lady Annalise Lyman.

Against his better judgment, Lieutenant Jeb Danvers undertakes one last secret mission for the Queen. She has made him an offer he cannot help but accept. One that will secure his financial future. But when he discovers that the jewels she has sent him to recover are in the possession of the beautiful Mariah MacFarlane, he knows the jewels aren’t the only things in need of rescue.

Captain Caleb Parker was the lone bachelor, holding out long after his fellow traitors had tied the knot. He held himself to no standard but to do good in the world. Until he met the countess. Lady Eleanor Grattling moved him in ways he'd not experienced, tempting him with images of a marriage he knew could never be. Her title and his low station would see to that. Still, every instinct drew him closer, determined to save her from Virgil Blackboot and the evil that threatened her children... moreCaptain Caleb Parker was the lone bachelor, holding out long after his fellow traitors had tied the knot.
