Mafia Enforcer
1987 book by Tom Renner and Cecil Kirby (former vice president of Satan's Choice M.C.)

As a high-ranking figure in both the Calabrian Mafia and the notorious biker gang Satan's Choice, Cecil Kirby participated in crimes ranging from extortion to murder. By becoming a double-agent for the FBI, Kirby exposed Mafia members of the highest level and was granted immunity for the crimes he committed. MAFIA ENFORCER tells the account of Kirby, who a veteran FBI agent referred to as "the best double-agent I have met in ten years as an FBI agent. He is suave, self-assured, and knows how to handle underworld figures." More than 70,000 copies sold.

Comments: "I have personally read this book and found it to be one of the best books yet! You get a great look into the life of a mafia hitman and Satan's Choice member."
