As World War II raged into its second year, Britain sought a powerful ally to join its cause - but the American public was sharply divided on the subject. The Canadian-born MI6 officer William Stephenson, with his knowledge and influence in North America, was chosen to change their minds by any means necessary.

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.

Part Blackhawk Down, part The Riddle of the Sands, former MI6 officer Harry Ferguson has written an extraordinarily gripping non-fiction thriller. Operation Kronstadt not only reveals the early days of intelligence services but also uncovers a truly dramatic story from the Russian Revolution involving a daring rescue attempt and a "mission impossible" against the best defended naval target in Russia.

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.

If anyone could be considered a Russian counterpart to the infamous British double-agent Kim Philby, it was Oleg Gordievsky. The son of two KGB agents and the product of the best Soviet institutions, the savvy, sophisticated Gordievsky grew to see his nation's communism as both criminal and philistine. He took his first posting for Russian intelligence in 1968 and eventually became the Soviet Union's top man in London, but from 1973 on he was secretly working for MI6.

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.

In 1942, the Gestapo sent out an urgent transmission: "She is the most dangerous of all Allied spies. We must find and destroy her." The target in their sights was Virginia Hall, a Baltimore socialite who talked her way into Special Operations Executive, the spy organization dubbed Winston Churchill's "Ministry of Ungentlemanly Warfare." She became the first Allied woman deployed behind enemy lines and - despite her prosthetic leg - helped to light the flame of the French Resistance, revolutionizing secret warfare as we know it.

1942: World War II is in full swing. Odette Sansom decides to follow in her war hero father’s footsteps by becoming an SOE agent to aid Britain and her beloved homeland, France. Five failed attempts and a plane crash later, she finally lands in occupied France to begin her mission. It is here that she meets her commanding officer, Captain Peter Churchill. As they successfully complete mission after mission, Peter and Odette fall in love. All the while, they are being hunted by the cunning German secret police sergeant, Hugo Bleicher, who finally succeeds in capturing them.

This book reveals the most complete picture ever of the KGB and its operations in the United States and Europe. It is based on an extremely top secret archive which details the full extent of its worldwide network. Christopher Andrew is professor of modern and contemporary history and chair of the history department at Cambridge University, a former visiting professor of national security at Harvard, a frequent guest lecturer at other United States universities, and a regular host of BBC radio and TV programs.

On June 6, 1944, 150,000 Allied troops landed on the beaches of Normandy and suffered an astonishingly low rate of casualties. A stunning military achievement, it was also a masterpiece of trickery. Operation Fortitude, which protected and enabled the invasion, and the Double Cross system, which specialized in turning German spies into double agents, tricked the Nazis into believing that the Allied attacks would come in Calais and Norway rather than Normandy.

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.

He was called the Hangman of the Gestapo, the "butcher of Prague", with a reputation as a ruthlessly efficient killer. He was the head of the SS, and the Gestapo, second-in-command to Heinrich Himmler. His orders set in motion the Kristallnacht pogrom of 1938 and, as the lead planner of Hitler's Final Solution, he chaired the Wannsee Conference, at which details of the murder of millions of Jews across Nazi-occupied Europe were toasted with cognac.

J. Robert Oppenheimer was one of the iconic figures of the 20th century, a brilliant physicist who led the effort to build the atomic bomb but later confronted the moral consequences of scientific progress. When he proposed international controls over atomic materials, opposed the development of the hydrogen bomb, and criticized plans for a nuclear war, his ideas were anathema to powerful advocates of a massive nuclear buildup during the anti-Communist hysteria of the early 1950s.

With intrigue that rivals the best le Carre novels, Russians Among Us tells the urgent story of Russia’s espionage efforts against the United States and the West from the end of the Cold War to the present.
