Abstract
In his great aria "La calumnia," Don Basillo, the music master of Rossini's Barber of Seville, graphically describes how evil whispers grow, with appropriate watering, into truly grand and injurious calumnies. For the less conniving among us, the same lesson may be read with opposite intent: in adversity, try to contain. The desire to pin evil deeds upon a single soul acting alone reflects this strategy; conspiracy theories have a terrible tendency to ramify like Basillo's whispers until the runaway solution to "whodunit" becomes "everybodydunit." But conspiracies do occur. Even the pros and pols now doubt that Lee Harvey Oswald [202] acted alone; and everybody did do it on the Orient Express. 2..
