President Lincoln's Spy

the long version

On the battlefield, Captain Fitz Dunaway is a man of action with a keen, intellectual prowess. But when he humiliates his commanding officer, he finds himself facing a court martial for his maverick behavior. Now his only chance to redeem himself is by working as a spy to uncover a plot to assassinate President Lincoln. Searching through gas-lit alleyways for traitors who will embrace him as one of their own, Fitz discovers just how fine the line is between allegiance to your cause--and allegiance to your country.
