Chaos: Charles Manson, the CIA, and the Secret History of the Sixties by Tom O'Neill with Dan Piepenbring is a riveting exploration of the infamous Manson murders and the disturbing connections O'Neill uncovers after a 20-year investigation. Initially hired to write a 30th-anniversary article on the Manson murders, O'Neill’s research quickly unearths unsettling links between Manson, covert government programs, and potential CIA mind-control experiments. Delving deep into FBI files, courtroom records, and interviews with sources close to the case, O'Neill questions the official narrative and uncovers chilling evidence of corruption and secrecy at the highest levels. Part true crime, part conspiracy theory, *CHAOS* is an eye-opening reexamination of one of America’s darkest chapters.
