The real story of how the federal government finally apprehended and convicted America’s most notorious criminal, Al Capone. Drawing on recently discovered government documents, wiretap transcripts, and Al Capone’s handwritten personal letters, New York Times bestselling author Jonathan Eig tells the dramatic story of the rise and fall of the nation’s most infamous criminal in rich new detail. From the moment he arrived in Chicago in 1920, Capone found himself in a world with limitless opportunity. Within a few years Capone controlled an illegal bootlegging business with annual revenue rivaling that of some of the nation’s largest corporations. Along the way he corrupted the Chicago police force and local courts while becoming one of the world’s first international celebrities. Legend credits Eliot Ness and his “Untouchables” with apprehending Capone, but Eig shows that this wasn’t so. In Get Capone, the man known as “Scarface” emerges as a complex man, doomed as much by his ego as by his vicious criminality. This is the real Al Capone.

From the Bestselling Author and Television Producer of MASTERS OF SEX, a True Story of Espionage and Mobsters, Based on the Never-Before-Released JFK Files, and Optioned by Warner Bros. Mafia Spies is the definitive account of America’s most remarkable espionage plots ever—with CIA agents, mob hitmen, “kompromat” sex, presidential indiscretion, and James Bond-like killing devices together in a top-secret mystery full of surprise twists and deadly intrigue. In the early 1960s, two top gangsters, Johnny Roselli and Sam Giancana, were hired by the CIA to kill Cuba’s Communist leader, Fidel Castro, only to wind up murdered themselves amidst Congressional hearings and a national debate about the JFK assassination. Mafia Spies revolves around the outlaw friendship of these two mob buddies and their fascinating world of CIA spies, fellow Mafioso in Chicago, Cuban exile commandos in Miami, beautiful Hollywood women, famous entertainers like Frank Sinatra’s Rat Pack in Las Vegas, Castro’s own spies in Havana and his double agents hidden in Florida, J. Edgar Hoover’s FBI snooping, and the Kennedy administration’s “Get Castro” obsession in Washington. Thomas Maier is among the first to take full advantage of the National Archives’ 2017–18 release of the long-suppressed JFK files, many of which deal with the CIA’s top secret anti-Castro operation in Florida and Cuba. With several new investigative findings, Mafia Spies is a spy exposé, murder mystery, and shocking true story that recounts America’s first foray into the assassination business, a tale with profound impact for today’s Trump era. Who killed Johnny and Sam—and why wasn’t Castro assassinated despite the CIA’s many clandestine efforts?
