A new edition of the spy classic by Robert Littell, New York Times bestselling master of the espionage thriller.

When a top-secret plan is leaked within CIA headquarters, lead operative Wanamaker has no choice but to "walk back the cat"-find the leak and stop it, at whatever cost.

Meanwhile, operative Silas Sibley-nicknamed "the Weeder" due to his talent for parsing intelligence gathered by experimental computer technology-is at work for the Company when he discovers information no one was ever meant to find. Driven by a personal vendetta and an obsession with his own purported ties to the country's Revolutionary legacy, the Weeder becomes enmeshed in a plot whose ramifications reach far beyond his usual desk work.

The Once and Future Spy is a surprising, complex spy novel as well as a psychological deep dive into obsession, loyalty, and American history that poses the question: whose truth should be believed?
