Operation Underworld is a tale of espionage and crime like no other, the unbelievable, first-ever account of the Allied war effort's clandestine coalition between the Mafia and the U.S. Government to protect New York, vanquish the Nazis by taking the fight to the enemy in the 1943 U.S. invasion of Sicily. It was an ingenious strategy carried out by some of history's most infamous heroes on both sides of the law. It was a Faustian bargain that brought homefront enemies together but one that ultimately succeeded in helping the Allies win World War II.
