On November 1, 1950, two Puerto Rican nationalists, Oscar Collazo and Griselio Torresola, nearly assassinated President Harry Truman. If this historical fact surprises you, you're not alone. American Gunfight, a new account by suspense novelist and Pulitzer Prize-winning film critic Stephen Hunter and journalist John Bainbridge Jr., examines this largely forgotten episode in meticulous detail, including the conspiracy surrounding it and the misconceptions associated with the would-be assassins. As the book makes clear, it's remarkable that these two men even came close to succeeding, given the disorganized nature of the plot. Intending to attack the president at the White House, they only learned in passing from a cab driver that it was being renovated and that Truman was in fact living at the nearby Blair House.
