Duplicity — H.D. Thomson

He wakes up from a car accident with a dead man beside him and a duffle bag in the back seat with over one hundred thousand dollars in cash and a loaded gun. He has no memory of his past or how he got there. His only clues are a photo with the address of a shelter and a driver's license. They lead him to Boston, but once there, he's left with more questions and a sense of imminent danger. But nothing prepares him for the phenomena he finds within himself. 

Katherine Spalding knows she's one of the lucky ones. Born with money and looks, raised and educated among Boston's elite, she has the respect and admiration of friends and the community. But her luck's about to turn to chaos when a tall, gorgeous man with the most incredible gray eyes stumbles into her life. Katherine doesn't know what to make of him. But is he saint or sinner, hero or villain or ... just plain crazy? Is she willing to find out, even at the risk of her life?
