David Stashower, author of "American Demon: Eliot Ness and the Search for America's Jack the Ripper." The book discusses a terrifying series of unexplained and gruesome murders that occurred in Cleveland, Ohio in the mid 1930's - and the efforts of Eliot Ness, fresh off of bringing Al Capone to justice, to identify and apprehend the killer. This was one of America's first serial killers- at a time when that term had not yet been coined.
