Coll Nolan left the Marine Corps at the end of the Vietnam War a hero, with no job and no future. He had only one ambition: to win the most money in Las Vegas history betting on major league baseball. To begin to do that he needed a bankroll to start him off, but had no idea how to amass it. A former marine buddy offers to get him a job with his family business in New York City, a prominent diamond import business. The menial, but high-paying, job he lands includes being a chauffeur and bodyguard for the company's Dutch-born owner, Bartel Vandermeer. It seems like work heaven-sent, but before long he's asked to perform acts that go far beyond driving a limo. Coll Nolan soon must run for his life from men who want him dead. They hunt him and find him, even under government protection in remote places. His Las Vegas goal begins to look like an impossible dream, unless he can get the money he needs, hone his baseball skills sharply enough to take on the gambling experts in Nevada and, at the same time, deal with the killers who stalk him. He calls upon all his military savvy to help him survive, and finds an ally in a most unexpected place. The support is a welcome stroke of luck, but like all Las Vegas bets, there are never any guarantees. An additional factor creeps into play: For Coll to realize his goal, he has to sidestep the death that threatens him daily for an entire baseball season...almost seven months. Coll knows, one way or another, it's going to be A Killer Season.
