On November 28, 1953, one of America's greatest mysteries occurred when a Army biochemist working with the CIA fell to his death from a hotel window in New York City. Twenty-two years later it was revealed that the scientist, Frank Olson, had been drugged with LSD days before his death. In 1996, the New York District Attorney's Office opened a murder investigation into Olson's strange death. And the strangeness surrounding Olson's death only widened.

Now the mystery is solved! And the truth will shock readers. Who murdered Frank Olson and why? What was the true nature of Olson's work for the CIA? What did CIA's secret mind-control experiments have to do with Frank Olson? Why has the government covered up the truth about Frank Olson for over 50 years? A Terrible Mistake answers all of these questions and more.
