Ruthless, emotionless, and deadly, Severin Cadogan, the Earl of Killburn, was England’s greatest secret weapon. One misstep put an end to his respectable career as sanctioned killer and informant. Fortunately, there’s plenty of evil to go around. When he’s approached by a potential client with a proposition involving the gentleman’s sister—it’s the last assignment Cadogan wants. Alas, he’s been made an offer he can’t refuse…and one he quickly finds himself enjoying for all the most depraved reasons.
