Based on hundreds of inside sources and secret documents, the author reveals the inner operations of the C.I.A., the world's largest and most sophisticated espionage apparatus, its players, and its clandestine relationships throughout the world Woodward's books on Watergate, the Supreme Court, and John Belushi were not so controversial as Veil. His deathbed visit to William Casey, former CIA head, has been disputed by Casey's wife. What Woodward knew about Casey's Iran-contra role was apparently withheld from Congress. All this smoke has drawn attention from the fire. Woodward's tale of attempted murders, payoffs to foreign leaders, covert contra aid, covert aid to Britain in the Falklands War, and anti-terrorist squads is formidable. He presents Casey's CIA as a dangerously illegal loose cannon on the deck of U.S. foreign policy. Richard B. Finnegan, Stonehill Coll., North Easton, Mass.
