A landmark collaboration between a thirty-year veteran of the CIA and a Pulitzer Prize-winning journalist, The Main Enemy is the inside story of the CIA-KGB spy wars, told through the actions of the men who fought them. Based on hundreds of interviews with operatives from both sides, The Main Enemy puts us inside the heads of CIA officers as they dodge surveillance and walk into violent ambushes in Moscow. This is the story of the generation of spies who came of age in the shadow of the Cuban missile crisis and rose to run the CIA and KGB in the last days of the Cold War.

But now, three Russian assets have been exposed - including one of her own - and the CIA is convinced there's a mole in the department. With years of work in question and lives on the line, Lyndsey is thrown back into life at the agency, this time tracing the steps of those closest to her.

Two years ago, a hostile Prime Minister launched the Monochrome inquiry, investigating "historical over-reaching" by the British Secret Service “to investigate historical over-reaching.” Monochrome’s mission was to ferret out any hint of misconduct by any MI5 officer—and allowed Griselda Fleet and Malcolm Kyle, the two civil servants seconded to the project, unfettered access to any and all confidential information in the Service archives in order to do so. But MI5’s formidable First Desk did not become Britain’s top spy by accident, and she has successfully thwarted the inquiry at every turn.

1926, and in a country still recovering from the Great War, London has become the focus for a delirious new nightlife. In the clubs of Soho, peers of the realm rub shoulders with starlets, foreign dignitaries with gangsters, and girls sell dances for a shilling a time. The notorious queen of this glittering world is Nellie Coker, ruthless but also ambitious to advance her six children, including the enigmatic eldest, Niven, whose character has been forged in the crucible of the Somme. But success breeds enemies, and Nellie’s empire faces threats from without and within.

Who exactly is Danziger? He's a writer of letters for illiterate immigrants on Manhattan's Lower East Side - "a steadfast practitioner of concealing and forgetting" for his clients, and perhaps for himself: He hints at a much worldlier past. What and whoever he really is or has been, he has a seemingly boundless knowledge of the city and its denizens. And he knows much more than the mere identity of the floating corpse.

Northern Ireland, spring 1981. Hunger strikes, riots, power cuts, a homophobic serial killer with a penchant for opera, and a young woman’s suicide that may yet turn out to be murder: on the surface, the events are unconnected, but then things—and people—aren’t always what they seem. Detective Sergeant Duffy is the man tasked with trying to get to the bottom of it all. It’s no easy job—especially when it turns out that one of the victims was involved in the IRA but was last seen discussing business with someone from the loyalist Ulster Volunteer Force.

1660 England. General Edward Whalley and his son-in law Colonel William Goffe board a ship bound for the New World. They are on the run, wanted for the murder of King Charles I—a brazen execution that marked the culmination of the English Civil War, in which parliamentarians successfully battled royalists for control.

Berlin, 1963. An early morning spy swap, not at the familiar setting for such exchanges, nor at Checkpoint Charlie, where international visitors cross into the East, but at a more discreet border crossing, usually reserved for East German VIPs. The Communists are trading two American students caught helping people to escape over the wall and an aging MI6 operative. On the other side of the trade: Martin Keller, a physicist who once made headlines, but who then disappeared into the English prison system.

At the height of WWII, five idealistic young Americans receive a mysterious letter from the OSS, asking them if they are willing to fight for their country. The men and women from very different backgrounds - a Texan athlete with German roots, an upper-crust son of a French mother and a wealthy businessman, a dirt-poor Midwestern fly fisherman, an orphaned fashion designer, and a ravishingly beautiful female fencer - all answer the call of duty, but each for a secret reason of his or her own. They bond immediately, in a group code-named Dragonfly.

His name was Feliks. He came to London to commit a murder that would change history. A master manipulator, he had many weapons at his command, but against him were ranged the whole of the English police, a brilliant and powerful lord, and the young Winston Churchill himself. These odds would have stopped any man in the world - except the man from St. Petersburg.

In his final hours in the Oval Office, the outgoing President grants a controversial last-minute pardon to Joel Backman, a notorious Washington power broker who has spent the last six years hidden away in a federal prison.
