A review by dianed
Beyond a Reasonable Duke by Deb Marlowe

What a delightful story. More madcap spy novel than historical romance. Laura Stokes shows up at Half Moon Street dressed in men's clothing and with a twisted ankle. Upon entering the house she promptly faints. What can be going on? The story then proceeds to go back a few weeks to let us know how Laura got here. She's created an elaborate disguise and Mr Lawrence McConnell in an effort to take revenge on the Marquess of Marstoke who has ruined her sister.
As part of her dealings as a man she meets the Duke of Rothmore. He seems to be working with Marstoke in a treasonous plot (but is he really?) Laura/Lawrence has the Duke fooled but not enough to get him to get her access to Marstoke who she is trying to kill. When the Duke discovers that Lawrence is actually a woman - he is intrigued and even more set on trying to protect her.
I won't give away the end but suffice it to say that Marstoke gets what what he deserves and the Duke gets a new duchess.
This is a fast enjoyable read that has enough surprises along the way to make it fun to discover what happens in the end. I would have liked to see how the story continued
