“Great talent, great imagination, and real been-there done-that authenticity.”
—Lee Child

“Not since Fleming charged Bond with the safety of the world has the international secret agent mystique been so anchored with an insider’s reality.”
—Noah Boyd, author of The Bricklayer and Agent X

Matthew Dunn knows his spycraft—and he proves it once again in Sentinel, his second electrifying Spycatcher novel. A former British M16 field officer trained in all aspects of intelligence collection, small-arms and explosives, military unarmed combat, and more, Dunn has an addition talent most other spies lack: he can really write! In Sentinel, Dunn brings back Agent Will Cochrane—whom Kirkus Reviews calls, “a Nietzschean hero who looks poised to give Lee Child’s Jack Reacher a run for his readers”—and sends him to Avacha Bay in eastern Russia, where he must infiltrate a top-secret submarine base, decode a cryptic message from a deep undercover operative, and quite possibly prevent a devastating war. Espionage fiction fans who regularly devour the works of Daniel Silva, Robert Ludlum, Alex Berenson, Ted Bell, Brad Thor, Vince Flynn, and Barry Eisler will discover there’s a new ace on the international thriller scene.
