On a grand tour to Italy with her cousin, wealthy heiress Marjorie Mayweather is braced for the adventure of a lifetime. After all, this is her chance for one last fling before surrendering herself to Frederick Clive-Bickerton, the well-heeled bachelor intent on marrying her.

But Frederick is the last thing on Marjorie’s mind when she meets the dashing yet chilly Captain Edward Grainger, a fellow resident at the Pensione Ferretti. Vexed by his indifference and enchanted by his ice-blue gaze, she finds herself magnetically drawn to this strangely private gentleman.

Edward must keep his distance, no matter how alluring he finds Marjorie to be. For he’s not really a military captain at all—he’s an undercover agent in pursuit of a notorious jewel thief reported to be staying at the pensione. Can Edward maintain his ruse long enough to nab the criminal among them…or will the affections of a young debutante unravel his entire investigation?
