The Mammoth Book of Famous Trials is a collection of 35 of the most famous trials of the 20th century. Recorded by the people who were there, some of the contributors include Truman Capote, Norman Mailer, Brian Masters, and Damon Runyon.

Among the cases included in this book are the following: The longest on record in the United States — of the deadly duo Bianchi and Buono for the dozen Hillside Stranglings; Brady and Hindley — the iconic case of multiple-child murder; the media frenzy surrounding Bruno Hauptmann's alleged murder of the infant son of Charles Lindberg; O.J.

Simpson's trial of the 1990s; the 1968 trial of eleven-year-old Mary Bell who was convicted for killing two little boys; the trial of Oscar Wilde; and the nine-month trial of Charles Manson.
