The Most Dangerous Game

A Russian submarine is reportedly lost just south of the Bering Sea, but a day later, her captain is found alive and well, talking to a couple of people (a Venezuelan spy and an undercover Ukrainian agent) in Caracas. A deep-cover intelligence unit called Bedell, Donovan, & Spencer assign former FBI agents Hank Schmidt, McGeorge Johnson, and James Johnson to ascertain where the sub is and what the captain's intentions are. Accompanied by Jordan Graham, a former assistant US attorney for the southern district of New York, the team uncover a conspiracy that threatens the unity of NATO's support of Ukraine as it fends off an invasion from Russia that involves nuclear weapons in Brussels, Hamburg, and Gdansk.

All isn't as it seems. Allies become villains and villains become allies as Hank and his team work against time to try to stop the Russians and Venezuelans from launching a nuclear attack on European soil that could lead directly to World War 3.
