Politician, man about town, war hero, and murderer: Dan Sickles led many lives, some of them improbable, turning disaster to advantage. Thomas Keneally, whose novels have been populated by heroes and outlaws alike, vividly captures Sickles's life and times. A Tammany politician, for good and ill, Sickles earned national notoriety for gunning down his friend Philip Barton Key, the son of Francis Scott Key, in what his peers in Congress took to be an excusable crime of passion. Sickles made a glorious comeback with the Civil War, when the regiment he raised distinguished itself time and again under fire at places such as Chancellorsville and Gettysburg--where, defying orders in a bold maneuver, Sickles helped secure the Union victory. "His tendency toward berserk and full- blooded risk was partly characteristic of the city he had grown up in, the age he lived in, and his own soul," writes Keneally. Admired by no less than Mark Twain, Sickles figures only as a footnote in many histories. Ably recounting his triumphs and defeats, Thomas Keneally brings him front and center in a tale that will delight Civil War buffs. --Gregory McNamee
