New York City mobster, had been involved in gangland wars for over thirty years when he was sent to the Atlanta Federal Penitentiary for a narcotics violation. There he found that his ex-boss Vito Genovese was running a crime ring of ninety ex-mobsters who were also imprisoned in the jail. He also learned that he was in disfavor with Genovese who believed that Valachi had informed drug agents about his narcotics operations. Valachi received from Genovese the Mafia's traditional 'kiss of death' - an embrace that marks the recipient for execution. In fear of his life, Valachi agreed to tell the Justice Department all he knew about the closely-kept secrets of the Costra Nostra. He spent months in Washington, protected by as many as two hundred federal marshals. ALS signed 'Joe,' one page, 8 x 10, September 17, 1965.
