Havana, the sultry spring of 1953: gambling is expensive, sex is cheap, and death is free. A half-hour by air from Miami, it's the world's hottest -- and most dangerous -- city. From the plush mobster casinos in Centro to the backstreet brothels on Zanja Street, you can get anything you want, for a price. The city is the linchpin of many empires: the Mafia's, the CIA's, numerous American corporations', El Presidente's, and even the vice lords' of Old Havana. It must be protected at all costs. But now there's a threat. A young lawyer, a kid named Castro, is giving speeches. He speaks of reform, of change, of self-determination. He speaks of...of revolution even.This danger must be dealt with. So, into the steamy, sunny climate of corruption come two men, both unafraid, both skilled, both tough as ball bearings. They would be friends in a sane world, for they are so similar in their capabilities and experiences. But now they have to be enemies, because the Cold War is at its apogee: one is American, the other Russian. The American is named Earl Swagger. A Medal of Honor winner on Iwo Jima, a toughened gunman from adventures in Hot Springs and the swamps of Mississippi, Earl has been conned by two young Old Boys of the CIA to become Our Gun in Havana.
