June 2, 2004 -- Historian Mark Perry's new book, Grant and Twain: The Story of a Friendship That Changed America, details a 15-month period in the mid-1880's when President Ulysses S. Grant and Mark Twain were writing two American masterpieces. Perry believes Grant's Personal Memoirs and Twain's Huckleberry Finn reveal a fixation the two men shared: the legacy of the Civil War and slavery.
