The Untouchables is an autobiographical memoir by Eliot Ness co-written with Oscar Fraley, published in 1957. The book deals with the experiences of Ness, who was a federal agent in the Bureau of Prohibition, as he fought crime in Chicago in the late 1920s and early 1930s with the help of a special team of agents handpicked for their incorruptibility, nicknamed The Untouchables.
