'Perfectly balancing romance and intrigue, this is a true page-turner' Publishers Weekly HE IS THE ICE-COLD DUKE Julian, the Duke of Hastings, is known for being aloof and utterly in control. For nine years, he's kept his distance from the only woman who ever cracked his icy exterior, burying himself in work as a top-secret government code-breaker. But when his latest assignment ensnares him in a lethal aristocratic plot, Julian has no choice but to enlist the help of his estranged wife. SHE IS THE PRIM DUCHESS To all of society, Caroline Hastings is the perfect duchess. For years she's masked her pain over her husband's abandonment behind a poised facade. But when Julian unexpectedly returns and sweeps them into a dangerous, covert mission, Caroline discovers her frozen duke isn't quite so indifferent in the bedroom after all. Now, locked in a dangerous chase through London's glittering ballrooms and dark back alleys, Julian and Caroline must catch a killer - before he catches them first.
