Undercover Duke

In the fourth Duke Dynasty novel, New York Times bestselling author Sabrina Jeffries, one of the best-known names in historical romance, weaves an enchanting Regency romance with a mystery at its core, as stepsiblings investigate the truth about their mother’s succession of beloved husbands—and their own surprising identities as eligible young nobles. For an uptight duke still nursing a broken heart, the last thing he needs is a pretend engagement with a vivacious and alluring young woman. As they’re drawn deeper into secret schemes, could she solve not just the mystery of his family, but the riddle of his heart as well? Bridgerton fans and readers of Madeline Hunter, Eloisa James, and Lisa Kleypas won't want to miss this humorous and clever new love story from the historical romance legend. Along with his stepsiblings, Sheridan Wolfe, Duke of Armitage, is determined to finally solve the mysteries behind the suspicious deaths of their mother’s three husbands. Tasked with investigating a possible suspect, Sheridan finds himself in dangerous proximity to her captivating daughter, Vanessa Pryde. But still haunted by a tragically lost love, the duke is resolved to resist the attraction—and avoid any “scheming” husband-hunters. Besides, lovely Miss Pryde seems utterly smitten with a roguish London playwright … Vanessa thinks a little scheming may be in order—for it’s Sheridan she truly has her sights, and her heart, set on. Her theatrical flirtation is intended only to break through his business-like demeanor and guarded emotions. And as Sheridan’s jealousy becomes aroused, the two soon find themselves propelled into a scheme of an altogether different kind, involving a pretend engagement, a secret inquiry—and a perhaps not-so-secret leap into true love …
