Devil's Game traces the amazing career of Charles A. Dunham, Civil War spy, forger, journalist, and master of dirty tricks. Writing for a variety of New York papers under alternate names, Dunham routinely faked stories, created new identities, and later boldly cast himself to play those roles. He achieved his greatest infamy when he was called to testify in Washington concerning Abraham Lincoln's assassination. Many parts of Dunham's career remain shadowy, but Cumming offers the first detailed tour of Dunham's convoluted, high-stakes, international deceits, including his effort to sell Lincoln on plans for a raid to capture Jefferson Davis. Exhaustively researched and unprecedented in depth, this carefully crafted assessment of Dunham's motives, personality, and the complex effects of his schemes changes assumptions about covert operations during the Civil War.
