or 50 years, residents of the French village of Pont-Saint-Esprit have tried to understand the "cursed bread" incident, a moment of terrifying mass insanity and hallucinations that left at least five dead and dozens in asylums. Now the mystery is solved: the CIA secretly spiked the bread from the bakery with enormous quantities of LSD as part of its cold war mind-control experiments, at least according to recently uncovered documents. The allegation originates with H P Albarelli Jr., an investigative journalist who uncovered the documents while researching his forthcoming book, A Terrible Mistake: The Murder of Frank Olson and the CIA's Secret Cold War Experiments.
