The Grey Wolf — Maynard Allington

In the wake of a failed military coup by a cadre of senior Soviet officers against Joseph Stalin in 1942, a British Intelligence agent is abandoned in Moscow by the Churchill government, which must deny any connection to the conspiracy. The agent, Antony Ryder, is now on his own in a scenario based on certain actual events in the USSR during World War II. Pitted against an equally resourceful NKVD agent, Ryder cannot afford to be taken alive. Intrigue, a passionate love affair, conflicted friendships, and betrayal drive this epic thriller to its riveting climax - a harrowing escape from Moscow's dreaded Lubyanka prison, and desperate race for freedom to an allied port on the White Sea.
