Its code name was “Operation Gold”, a wildly audacious CIA plan to construct a clandestine tunnel into East Berlin to tap into critical KGB and Soviet military telecommunication lines. The tunnel, crossing the border between the American and Soviet sectors, would have to be 1,500 feet (the length of the Empire State Building) with state-of-the-art equipment, built and operated literally under the feet of their Cold War adversaries.

In the aftermath of the Cold War, American intelligence caught three high-profile Russian spies: Aldrich Ames, Edward Lee Howard, and Robert Hanssen. However, rumors have long swirled of another mole, one perhaps more damaging than all the others combined. Perhaps the greatest traitor in American history, perhaps a Russian ruse to tear the CIA apart, or perhaps nothing more than a bogeyman, he is often referred to as the Fourth Man.

Senator Frank Church of Idaho was an unlikely hero. He led congressional opposition to the Vietnam War and had become a scathing, radical critic of what he saw as American imperialism around the world. But he was still politically ambitious, privately yearning for acceptance from the foreign policy establishment that he hated and eager to run for president. Despite his flaws, Church would show historic strength in his greatest moment, when in the wake of Watergate he was suddenly tasked with investigating abuses of power in the intelligence community.

While getting into his car on the evening of February 16, 1978, the chief of the CIA's Moscow station was handed an envelope by an unknown Russian. Its contents stunned the Americans: details of top-secret Soviet research and development in military technology that was totally unknown to the United States.

Spies is the history of the secret war that Russia and the West have been waging for a century. Espionage, sabotage, and subversion were the Kremlin’s means to equalize the imbalance of resources between the East and West before, during, and after the Cold War. There was nothing “unprecedented” about Russian meddling in the 2016 US presidential election. It was simply business as usual, new means used for old ends.

From a master of popular history, the lively, immersive story of the race to seize Berlin in the aftermath of World War II as it’s never been told before.

No espionage missions have been kept more secret than those involving American submarines. Now, Blind Man's Bluff shows for the first time how the navy sent submarines wired with self-destruct charges into the heart of Soviet seas to tap crucial underwater telephone cables. It unveils how the navy's own negligence might have been responsible for the loss of the USS Scorpion, a submarine that disappeared, all hands lost, 30 years ago.

In this gripping narrative, Ben Macintyre tackles one of the most famous prison stories in history and makes it utterly his own. During World War II, the German army used the towering Colditz Castle to hold the most defiant Allied prisoners. For four years, these prisoners of the castle tested its walls and its guards with ingenious escape attempts that would become legend. But as Macintyre shows, the story of Colditz was about much more than escape.

At the end of World War II, the United States was considered the victor over tyranny and a champion of freedom. But it was clear—to some—that the Soviet Union was already seeking to expand and foment revolution around the world, and the American government’s strategy in response relied on the secret efforts of a newly formed CIA. Chronicling their fascinating lives, Scott Anderson follows the exploits of four spies. Despite their ambitions, time and again their efforts went awry, thwarted by ham-fisted politicking and ideological rigidity at the highest levels of the government.

How did the US Navy - the branch of the US military tasked with patrolling the oceans - ever manage to produce a unit of raiders trained to operate on land? And how, against all odds, did that unit become one of the world’s most elite commando forces, routinely striking thousands of miles from the water on the battlefields of Iraq, Afghanistan, Syria, even Central Africa?

Antonio Mendez and his future wife, Jonna, were CIA operatives working to spy on Moscow in the late 1970s, at one of the most dangerous moments in the Cold War. Soviets kept files on all foreigners, studied their patterns, tapped their phones, and even planted listening devices within the US embassy. In short, intelligence work was effectively impossible. The Soviet threat loomed larger than ever. The Moscow Rules tells the story of the intelligence breakthroughs that turned the odds in America's favor.

In Mossad, authors MichaelBar-Zohar and Nissim Mishal take us behind the closed curtain with riveting, eye-opening, boots-on-the-ground accounts of the most dangerous, most crucial missions in the agency's 60-year history.

Just days after the 9-11 attacks, a senior Pentagon analyst eased her red Toyota Echo into traffic and headed to work. She never saw the undercover cars tracking her every turn. As she settled into her cubicle on the 6th floor of the Defense Intelligence Agency in Washington, FBI Agents and twitchy DIA officers were hiding in nearby offices. For this was the day that Ana Montes--the US Intelligence Community superstar who had just won a prestigious fellowship at the CIA--was to be arrested and publicly exposed as a secret agent for Cuba.

From the acclaimed author of JFK and Vietnam comes a book that uncovers the government's role in the Kennedy assassination more clearly than any previous inquiry. What was the extent of the CIA's involvement with Lee Harvey Oswald? Why was Oswald's file tampered with before the assassination of John F. Kennedy?

The Venona Files are several intercepted communiques between the Soviet Union and American Communists following WWII. Some historians and journalists are starting to regard the Cold-War-era American Communist Party as nothing more than a quaint club of polite if misguided ideologues. In The Venona Secrets, Herbert Romerstein and Eric Breindel intend to create a new impression of treacherous Americans "who willfully gave their primary allegiance to a foreign power, the USSR."

In The Ghost, investigative reporter Jefferson Morley tells Angleton's dramatic story, from his friendship with the poet Ezra Pound through the underground gay milieu of mid-century Washington to the Kennedy assassination to the Watergate scandal. From the agency's MKULTRA mind-control experiments to the wars of the Mideast, Angleton wielded far more power than anyone knew.

In the fall of 1961, KGB assassin Bogdan Stashinsky defected to West Germany. After spilling his secrets to the CIA, Stashinsky was put on trial in what would be the most publicized assassination case of the entire Cold War.

Skripal’s first-hand accounts and experiences reveal the high stakes of a new spy game that harks back to the chilliest days of the Cold War.

The JFK story remains unsettled well into the 21st century, no matter what the various conspiracy and anti-conspiracy theorists may proclaim.

The fascinating, improbable true story of Maxwell Knight - the great MI5 spymaster and inspiration for the James Bond character M. Maxwell Knight was perhaps the greatest spymaster in history. He did more than anyone in his era to combat the rising threat of fascism in Britain during World War II, in spite of his own history inside this movement. He was also truly eccentric - a thrice-married jazz aficionado who kept a menagerie of exotic pets - and almost totally unqualified for espionage. Yet he had a gift for turning practically anyone into a fearless secret agent.

In this meticulously researched classic of the JFK conspiracy genre that Library Journal calls "sensational", Mark North argues convincingly that President John F. Kennedy died as the result of a plot masterminded by Louisiana Mafia chieftain Carlos Marcello - and, more importantly, that FBI chief J. Edgar Hoover learned early on about the plan but did nothing to stop it. Hoover warned no one - not the Dallas police, not the Secret Service. His motives, North suggests, stemmed from a fervent hatred of Kennedy and fear that the President would eventually fire him.

Working with thousands of previously unreleased documents and drawing on more than one thousand interviews, with many witnesses speaking out for the first time, Joan Mellen revisits the investigation of New Orleans district attorney Jim Garrison, the only public official to have indicted, in 1969, a suspect in President John F. Kennedy's murder. Garrison began by exposing the contradictions in the Warren Report, which concluded that Lee Harvey Oswald was an unstable pro-Castro Marxist who acted alone in killing Kennedy.

As the son-in-law of Egyptian president Gamal Abdel Nasser and a close advisor to his successor, Anwar Sadat, Ashraf Marwan had access to the deepest secrets of the country's government. But he himself had a secret: he was a spy for the Mossad, Israel's intelligence service. Under the codename "The Angel", Marwan turned Egypt into an open book for the Israeli intelligence services and, by alerting the Mossad in advance of the joint Egyptian-Syrian attack on Yom Kippur, saved Israel from a devastating defeat.
