Famed for her Mary Russell mysteries and novels featuring Kate Martinelli, New York Times best-selling author Laurie R. King has amassed a large and devoted following.

His existence shattered by the Great War, Bennett Grey is investigated by an American agent who thinks he may be useful for protecting national security. U.S. Bureau of Investigation agent Harris Stuyvesant's first inclination is to let his fists do the talking. But he's well out of his jurisdiction, having traveled across the Atlantic to dig up clues on an Englishman he believes responsible for terrorist acts in the States. After turning up a lead that draws him from London far into the English countryside, Harris meets Bennett Grey, a shell-shocked veteran whose war wounds left him with a unique talent that may hold the key to cracking the case.
