Hi, this is Charles Leerhsen, the author of Blood and Smoke: A True Tale of Mystery, Mayhem and the Birth of the Indy 500, to be published on May 3 by Simon and Schuster. It's a deep and hopefully exhilarating dive into the early car culture, the origins of auto racing and, of course, the first 500-mile sweepstakes, conducted 100 years ago this spring. "History comes alive," says Kirkus Reviews, "a fascinating tale." You can learn more about the book at my website, but I'd be happy to try and answer any questions here.
