AUTHOR’S NOTE The First Assassin is a work of fiction, and specifically a work of historical fiction—meaning that much of it is based on real people, places, and events. My goal never has been to tell a tale about what really happened but to tell what might have happened by blending known facts with my imagination. Characters such as Abraham Lincoln, Winfield Scott, and John Hay were, of course, actual people. When they speak on these pages, their words are occasionally drawn from things they are reported to have said. At other times, I literally put words in their mouths. Historical events and circumstances such as Lincoln’s inauguration, the fall of Fort Sumter, and the military crisis in Washington, D.C., provide both a factual backdrop and a narrative skeleton. Throughout, I have tried to maximize the authenticity and also to tell a good story. Thomas Mallon, an experienced historical novelist, has described writing about the past: The attempt to reconstruct the surface texture of that world was a homely pleasure, like quilting, done with items close to hand. For me, the items close to hand were books and articles. Naming all of my sources is impossible. I’ve drawn from a lifetime of reading about the Civil War, starting as a boy who gazed for hours at the battlefield pictures in The Golden Book of the Civil War, which is an adaptation for young readers of The American Heritage Picture History of the Civil War by Bruce Catton. Yet several works stand out as especially important references. The first chapter owes much to an account that appeared in the New York Tribune on February 26, 1861 (and is cited in A House Dividing, by William E. Baringer). It is also informed by Lincoln and the Baltimore Plot, 1861, edited by Norma B. Cuthbert.
