Chicago´s unique brand of ball is sixteen-inch slow pitch, played in leagues all over the city for more than a century. But in politics, in business, and in law enforcement, the game is hardball. Sara Paretsky is the author of thirteen previous books, including eleven V. I. Warshawski novels. She is the winner of many awards, including the Cartier Diamond Dagger Award for lifetime achievement from the British Crime Writers' Association.
