Lucas Delgado Guerrero's skin is too brown and his accent too foreign for him to feel truly at home in England. Returning to Mexico, which he scarcely remembers, however, is hardly a choice. So he remains in London, publishing an illegal newspaper devoted to reformist and revolutionary causes. One of his most popular writers is the intriguing and mysterious Polly Dicax, who delivers sharp, witty screeds by messenger every week.

At twenty-five, Lady Honora Pearce is too busy writing seditious treatises to pay much attention to men. Especially when marrying would mean giving up the very rights she argues for in her fierce diatribes. She is, however, intrigued by the editorials written by one of her publishers. Here, at least, is a man with worthy ideas and ideals. Not that she ever expects to meet him, since both their identities must remain secret. But everything changes when circumstances force her to deliver her weekly column herself and, on the heels of her arrival at the printer's shop, the police raid the premises.

To protect the shopkeeper and themselves, Honora and Lucas must hide together in a small chamber. They shouldn't have to kiss, but somehow, they do. And when Honora finds she can't stay away, Lucas discovers he can't refuse her, even if he can never be more than her bit of rough.
