Court Gentry's flight on a CIA transport plane is interrupted when a security team brings a hooded man aboard. They want to kick Gentry off the flight but are overruled by CIA headquarters. The mystery man is being transported to England where a joint CIA/MI6 team will interrogate him about a mole in Langley. When they land in an isolated airbase in the UK, they are attacked by a hostile force who kidnaps the prisoner. Only Gentry escapes. His handlers send him after the attackers, but what can one operative do against a trained team of assassins?

The first agent disappearance was a puzzle. The second was a mystery. The third was a conspiracy. Intelligence operatives around the world are disappearing. When a missing American agent re-appears in Venezuela, Court Gentry, the Gray Man, is dispatched to bring him in, but a team of assassins has other ideas. Court escapes with his life and a vital piece of intelligence. Meanwhile, CIA agent Zoya Zakharova is in Berlin. Her mission: to infiltrate a private intelligence firm with some alarming connections. The closer she gets to answers, the less likely she is to get out alive.

Fresh off his first mission back with the CIA, Court Gentry secures what seems like a cut-and-dried contract job: A group of expats in Paris hires him to kidnap the mistress of Syrian dictator Ahmed Azzam to get intel that could destabilize Azzam's regime. Court delivers Bianca Medina to the rebels, but his job doesn't end there. She soon reveals that she has given birth to a son, the only heir to Azzam's rule - and a potent threat to the Syrian president's powerful wife. Now, to get Bianca's cooperation, Court must bring her son out of Syria alive.

After five years on the run, Court Gentry is back on the inside at the CIA. But his first mission makes him wish he had stayed on the outs when a pair of Chinese agents try to take him down in Hong Kong. Normally the Chinese prefer to stay eyes-only on foreign agents. So why are they on such high alert? Court's high stakes hunt for answers takes him across Southeast Asia and leads to his old friend, Donald Fitzroy, who is being held hostage by the Chinese.

Before he was the Gray Man, Court Gentry was Sierra Six, the junior member of a CIA action team. In their first mission, they took out a terrorist leader, at a terrible price. Years have passed. The Gray Man is on a simple mission when he sees a ghost: the long-dead terrorist, but he's remarkably energetic for a dead man. A decade of time hasn't changed the Gray Man. He isn't one to leave a job unfinished or a blood debt unpaid.

Ex-CIA master assassin Court Gentry has always prided himself on his ability to disappear at will, to fly below the radar and exist in the shadows - to survive as the near-mythical Gray Man. But when he takes revenge upon a former employer who betrayed him, he exposes himself to something he’s never had to face before. A killer who is just like him. Code-named Dead Eye, Russell Whitlock is a graduate of the same ultra-secret Autonomous Asset Program that trained and once controlled Gentry.

Ex-CIA assassin Court Gentry thought he could find refuge living in the Amazon rain forest. But his bloody past finds him when a vengeful Russian crime lord forces him to go on the run once again. Court makes his way to one of the only men in the world he can trust - and arrives too late. His friend is dead and buried. Years before, Eddie Gamboa had saved Court's life. Now, Eddie has been murdered by the notorious Mexican drug cartel he fought to take down. And Court soon finds himself drawn into a war he never wanted.

Four years ago, assassin Court Gentry was betrayed by his handlers in the CIA. Now, an old comrade returns to haunt him - and to force him on a mission against his will. With his ruthless employers on one side, his former friends on the other, and a doomed mission ahead, Court Gentry would kill to get out of this one alive.

Court Gentry is known as The Gray Man—a legend in the covert realm, moving silently from job to job, accomplishing the impossible, and then fading away. And he always hits his target. But there are forces more lethal than Gentry in the world. And in their eyes, Gentry has just outlived his usefulness. Now, he is going to prove that for him, there's no gray area between killing for a living-and killing to stay alive.

When you kick over a rock, you never know what's going to crawl out. Alex Velesky is about to discover that the hard way. He's stolen records from the Swiss bank that employs him, thinking that he'll uncover a criminal conspiracy. But he soon finds that he's tapped into the mother lode of corruption. Before he knows it, he's being hunted by everyone from the Russian mafia to the CIA. Court Gentry and his erstwhile lover, Zoya Zakharova, find themselves on opposites poles when it comes to Velesky. They both want him, but for different reasons. 

A desperate Kremlin takes advantage of a military crisis in Asia to simultaneously strike into Western Europe and invade east Africa in a bid to occupy three rare Earth mineral mines that will give Russia unprecedented control over the world's hi-tech sector for generations to come. Pitted against the Russians are a Marine lieutenant colonel pulled out of a cushy Pentagon job, a French Special Forces captain and his intelligence operative father, a young Polish partisan fighter, an A-10 Warthog pilot, and the commander of an American tank platoon....
