Adam Selzer is the author of more than a dozen books, including several novels and the acclaimed Smart Aleck's Guide to American History. While doing research for stories to tell on the ghost tours that he's run in Chicago for nearly a decade, he developed a knack for discovering new clues to old mysteries. With his trademark smart-alecky humor, he's applied himself to wading through mountains of death certificates, poring through reels and reels of newspaper archives, and, occasionally, sticking his head right into crumbling old tombs. He lives with his wife in a small Chicago apartment where the cats have them outnumbered and know it. Visit him online at Adamselzer.com.
