Twenty years ago, Cornelia Gray was the most brilliant and dangerous CIA operative in the world. Her closest friend and mentor was Deputy Executive Director Winston Beckham, number four man at the CIA. One evening in Washington DC, leaving a charity function with his wife, Beckham was shot dead by an assailant with a long-range sniper rifle. With the help of an anonymous tip, the FBI arrested Cornelia Gray and allowed the CIA to take the lead in her interrogation. After withstanding three days of torture, Gray killed both of her interrogators and escaped, going underground without a single word to colleagues or her clueless family. In the weeks leading up to Beckham's murder, there were a series of national security leaks traced to the upper levels of the CIA. One faction believed that Beckham had become a traitor and was behind the devastating leaks, but no evidence to support this was found. Another faction believed that Beckham had discovered that Cornelia Gray was a mole and that she killed Beckham to silence him, but no evidence was ever found to support this theory. Whichever theory was true, the leaks stopped after Beckham's murder. Beckham's boss, Executive Director Chase Marshall, had to accept the possibility that someone at a high level of the CIA had turned. In response, he created an autonomous splinter group with the power to investigate anyone in the Agency, the spy world equivalent of internal affairs. The group was named Cerberus, a three-headed monster to be run by three of Cornelia Gray's former colleagues: Kevin Tagg, Wendell Abbott, and Christina Gold. Now, twenty years after Beckham's murder, someone in the intelligence community is once again leaking information to our enemies. The new leaks threaten to derail an operation playing out in North Korea. When it is confirmed that the leaks are coming from someone closely connected to Cerberus itself, they take the dangerous, and previously unthinkable, step of bringing the fugitive Gray back into service to help them find the mole. They find Gray through the efforts of a junior agent, Sara Beckham (daughter of Winston Beckham), who has compiled convincing evidence that Gray did not kill her father twenty years earlier. In exile, Gray was living quietly as "Janet Lester," a diminished life in a small NY state town cut off from her former personal and professional ties. But now, with her recapture, Gray is given a second chance to return to the "spy game" she loves and to reunite with family she left behind.
