The last of the Dominika Egorova spy trilogy, finished as Matthews was dying. Russian intelligence has a mole of its own, in place for decades and about to be appointed to run the CIA, and double-agent Dominika is the only person who can identify her — which means she has to expose her without exposing herself to the Kremlin and Putin, who keeps a very close and personal eye on this ballerina turned agent. It runs through Washington, Hong Kong, Istanbul, and Moscow, and Matthews spends it closing out everybody’s account. He was a CIA case officer for thirty-three years and it shows in the small things: What it costs to run an agent, how people actually get caught, and how rarely it ends well. And he brings the trilogy to a close with the same cold-eyed detachment of career spy. Like the ending or not, it rings true.
