The author of the book Great Chicago Fires has been arrested in Chicago for arson. As a Chicago Sun-Times story by Maureen O’Donnell reports, former firefighter David Cowan was also the co-author of To Sleep with the Angels, a book about a 1958 fire in one of the city’s Catholic parishes that killed 92 school children and 3 nuns, a book O’Donnell calls it “one of the saddest Chicago books ever written.” Cowan was scheduled to sign copies of his books at Chicago’s Printers Row Book Fair last weekend but instead he was arrested and faces charges of setting fire to a church where he had been fired as a janitor. His wife, who spotted him running from the fire, “He wanted it [the fire] to be seen. It was just a cry for help.”
