About the Author
Sabrina Jeffries is the New York Times bestselling author of more than 50 novels and works of short fiction (some written under the pseudonyms Deborah Martin and Deborah Nicholas).
Whatever time not spent speaking to organizations around the country or writing in a coffee-fueled haze is spent traveling with her husband and adult autistic son or indulging in one of her passions – jigsaw puzzles, chocolate, and music.
With over 9 million books in print in more than 20 languages, the North Carolina author never regrets tossing aside a budding career in academics (she has a Ph.D. in English literature) for the sheer joy of writing fun fiction, and hopes that one day a book of hers will end up saving the world. She always dreams big.

About the Book
Love is intriguing. . .
Along with his half-siblings, Sheridan Wolfe, Duke of Armitage, is determined to solve the mysteries behind the suspicious deaths of their mother’s three husbands. His investigations bring him into dangerous proximity with the captivating Vanessa Pryde, but the duke, still haunted by a tragically lost love, is resolved to resist the attraction. Besides, lovely Miss Pryde seems utterly smitten with a roguish London playwright. . .
Vanessa’s theatrical flirtation is intended only to break through the duke’s business-like demeanour and guarded emotions, for it is Sheridan she truly has her sights, and her heart, set on. As the duke’s jealousy becomes evident, the two find themselves propelled into a scheme involving a pretend engagement, a secret inquiry – and a perhaps not-so-secret leap into true love. . .


To my late mom, I miss you
and wish you hadn’t gone so soon.
Thanks for all the years of looking out for us and Dad.


LONDON SOCIETY TIMES
THE LAST DUKE STANDING
Dear readers,
I, your esteemed correspondent, cannot believe it. Not only has that randy devil, the Duke of Thornstock, actually married, but he chose Miss Olivia Norley as his bride! And this, after she refused him most soundly years ago. He must have reformed because Yours Truly knows full well Miss Norley would never have married him otherwise.
This means that his half brother, Sheridan Wolfe, the Duke of Armitage, is the only one of the dowager duchess’s offspring not yet married. What a coup it will be for the young lady who snags him! Although the usual wagging tongues claim he must needs marry a fortune to shore up his estate, that will not matter to anyone with an eligible daughter. He’s a duke, after all, and a young, handsome one at that, which is particularly rare. I daresay he will not be left unwed for long.
How delicious it will be to watch him hunt for his bride. Armitage is discreet where Thornstock was not, and he’s more reclusive even than his other half brother, the Duke of Greycourt. So it will have to be a most intriguing lady to pierce his armor and seize the rare heart that surely beats beneath. We await the result with bated breath.


Chapter One
Armitage House, London
November 1809
“The Duke of Greycourt is here to see you, Your Grace.”
Sheridan Wolfe, the Duke of Armitage, looked up from the list of horses in the stables of his family seat, Armitage Hall, to find his butler in the doorway. “Show
