Duchess in Disguise by Violet Hamers

“Ten days to find a murderer, and all I can think about is tasting your lips…”

Isobel arrives from Scotland expecting a sisterly reunion. Instead, her father demands the impossible: take her twin’s place for ten days and discover who poisoned her…
Duke Richard knows his friend’s bride is supposed to be a prim and proper lady. Not the sharp-tongued vixen standing before him. So when Isobel’s acting is not convincing enough, he must step in… if they want to find the villain among them.
Bound together until the wedding, Richard realizes this woman might be his undoing. For there’s something a lot more dangerous than the murderer: his burning desire to taste Isobel’s lips…

*If you like a realistic yet steamy depiction of the Regency and Victorian era, then Duchess in Disguise is the novel for you.
