The Untouchables is an autobiographical memoir about Eliot Ness co-written by Oscar Fraley, published in 1957. The book deals with the experiences of Eliot Ness, a federal agent in the Bureau of Prohibition, as he fights 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.
