"The Gray Man deals in death with mathematical precision, but this time he may finally find himself on the wrong side of the equation ... Court Gentry's flight on a CIA transport plane is interrupted when a security team brings a hooded man aboard. The mysterious passenger is being transported to England where a joint CIA/MI6 team will interrogate him about a mole in Langley. When they land at an isolated airbase in the UK, they are attacked by a hostile force that kidnaps the prisoner. Gentry, the lone survivor, is ordered to track down the assassins and rescue the asset. In Virginia, an assault on a CIA safe house leaves dead and wounded agents littering a suburban neighborhood. The object of the attack is Court's former lover, Zoya Zakharova. She escapes, but with a team of killers on her trail. Now, two different agents on two different continents are battling blind against the impossible--but each may be holding the piece the other needs to fight their way out"--
