In Manitoba, Winnipeg, a bronze statue of Sir William Stephenson proudly stands as a testament to this hero’s legacy. He was a dedicated soldier, a gifted inventor, an extraordinary businessman, and a spy. From his humble Canadian beginnings, William Stephenson enlisted in the Royal Flying Corps and rapidly moved through the ranks of the armed forces.

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.

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.

Many terms were bestowed upon the mysterious Fritz Duquesne throughout his colorful life, but perhaps the most fitting ever attributed to him was: "the most dangerous prisoner to have ever lived." But before this Boer warrior-turned-spy reached the heights of infamy that awarded him such acclaim, Fritz Joubert Duquesne lived a life of adventure that many people wouldn’t experience in a hundred lifetimes. From a young age, Fritz harboured a burning resentment toward the British army, stemming from the brutal treatment suffered by his family during the Anglo-Boer wars.

Eddie Chapman was a charming criminal, a con man, and a philanderer. He was also one of the most remarkable double agents Britain has ever produced. Inside the traitor was a man of loyalty; inside the villain was a hero. The problem for Chapman, his spymasters, and his lovers was to know where one persona ended and the other began.

A Man Called Intrepid is the account of the world’s first integrated intelligence operation and of its master, William Stephenson. Codenamed INTREPID by Winston Churchill, Stephenson was charged with establishing and running a vast, worldwide intelligence network to challenge the terrifying force of Nazi Germany. Nothing less than the fate of Britain and the free world hung in the balance as INTREPID covertly set about stalling the Nazis by any means necessary.

In 1942, in a quiet village in the leafy English Cotswolds, a thin, elegant woman lived in a small cottage with her three children and her husband, who worked as a machinist nearby. Ursula Burton was friendly but reserved, and spoke English with a slight foreign accent. By all accounts, she seemed to be living a simple, unassuming life. Her neighbors in the village knew little about her. They didn’t know that she was a high-ranking Soviet intelligence officer. They didn’t know that her husband was also a spy, or that she was running powerful agents across Europe.

From Pulitzer Prize finalist Annie Jacobsen, the untold story of the CIA's secret paramilitary units.

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.

As England prepares to fight the Nazis, three very different women answer the call to mysterious country estate Bletchley Park, where the best minds in Britain train to break German military codes. Vivacious debutante Osla is the girl who has everything - beauty, wealth, and the dashing Prince Philip of Greece sending her roses - but she burns to prove herself as more than a society girl, and puts her fluent German to use as a translator of decoded enemy secrets.

The spy novel emerged from the intrigues of the mid-20th century for good reason. The war with the Third Reich involved an unseen cloak-and-dagger struggle between the participants, but beyond that, an even larger and longer contest took place in the shadows. The men responsible for this unprecedented leaking of life-or-death information would enter history as the Cambridge Five - though in fact, they may have been only the core of a much larger group.

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.

It is 1936, and Nancy Wake is an intrepid Australian expat living in Paris who has bluffed her way into a reporting job for Hearst newspaper when she meets the wealthy French industrialist Henri Fiocca. No sooner does Henri sweep Nancy off her feet and convince her to become Mrs. Fiocca than the Germans invade France and she takes yet another name: a code name. As Lucienne Carlier, Nancy smuggles people and documents across the border and earns a new nickname from the Gestapo for her remarkable ability to evade capture: The White Mouse.

Virginia Hall left her comfortable Baltimore roots in 1931 to follow a dream of becoming a Foreign Service Officer. After watching Hitler roll over Poland and France, she enlisted to work for the British Special Operations Executive (SOE), a secret espionage and sabotage organization. She was soon deployed to occupied France where, if captured, imprisonment and torture at the hands of the Gestapo was all but assured.

In the late 1970s, the National Security Agency still did not officially exist - those in the know referred to it dryly as the No Such Agency. So why, when NSA engineer Charles Gandy filed for a visa to visit Moscow, did the Russian Foreign Ministry assert with confidence that he was a spy? Outsmarting honey traps and encroaching deep enough into enemy territory to perform complicated technical investigations, Gandy accomplished his mission in Russia but discovered more than State and CIA wanted him to know.
