A twisting tale featuring a calculating marquess, a marriage of convenience, and a touch of mystery from the New York Times–bestselling author.

Why would the Marquess of Heppleford marry someone like Tilly—plump, penniless, and paid companion to a deeply unpleasant duchess? Why, to insure his inheritance of course, by following the demands of his late father’s will. Once they’re wed, he can simply return to his rakish adventures in France.

Tilly, unfortunately, is unaware of the real reason this highly eligible bachelor wants her as a wife—and is heartbroken when she learns the truth. But when he comes back from Paris, he will be shocked to discover that his plain bride has made herself over into a seductive, sophisticated beauty bent on revenge—all while danger lurks in the shadows...
