Ropes & Gray counsel David Stewart has clerked at the U.S. Supreme Court, argued cases there and continues to file amicus briefs in high court cases. But the life of the writer is quickly consuming the life of the lawyer.

His fourth book, The Lincoln Deception, is a historical mystery released just this week about the John Wilkes Booth conspiracy to assassinate the president, in which a white doctor and a black newspaper publisher in 1900 try to uncover the explosive secret that conspirator Mary Surratt conveyed to prosecutor John Bingham before she was hanged. He is already at work on his fifth, a nonfiction work about James Madison that should hit the bookstands and online outlets during the second half of 2014.
