Book excerpt: For the 50th anniversary of the Watergate break-in: The untold story of President Richard Nixon, CIA Director Richard Helms, and their volatile shared secrets that ended a presidency. Scorpions' Dance by intelligence expert and investigative journalist Jefferson Morley reveals the Watergate scandal in a completely new light: as the culmination of a concealed, deadly power struggle between President Richard Nixon and CIA Director Richard Helms. Nixon and Helms went back decades; both were 1950s Cold Warriors, and both knew secrets about the disastrous Bay of Pigs invasion of Cuba as well as off-the-books American government and CIA plots to remove Fidel Castro and other leaders in Latin America. Both had enough information on each other to ruin their careers. After the Watergate burglary on June 17, 1972, Nixon was desperate to shut down the FBI's investigation. He sought Helms' support and asked that the CIA intervene—knowing that most of the Watergate burglars were retired CIA agents, contractors, or long-term assets with deep knowledge of the Agency's most sensitive secrets. The two now circled each other like scorpions, defending themselves with the threat of lethal attack. The loser would resign his office in disgrace; the winner, however, would face consequences for the secrets he had kept. Rigorously researched and dramatically told, Scorpions' Dance uses long-neglected evidence to reveal a new perspective on one of America's most notorious presidential scandals.
