What to read after Gangbusters:?

The American Mafia is legendary for its ability to survive and flourish in the face of all attempts to stamp it out. But when New York's Lucchese Family, the most successful and powerful group of organized criminals in American history, loses a long battle with its law enforcement adversaries, it signals the end of a notorious era.

Gangbusters is the story of how a colorful coterie of FBI agents, prosecutors, and police detectives overcame the early years of bureaucratic inertia, high-level political corruption, and interagency rivalry to destroy the last great Mafia dynasty. In a decade of hand-to-hand combat, they brought down the men long considered untouchable--Tommy Three Fingers, Tony Ducks, Christy Ticks, Tom Mix, Gas Pipe, and the Terminator--and an organization that had its fingers deep into trucking sanitation and the garment industry in New York City.

Based on interviews with antagonists on both sides of the law, courts records, transcripts, and police intelligence files, the book tells the history of a criminal enterprise from the inside--from the men who made it flourish to the men who eventually brought it down.
