Jonas Wilde, Britain's top political assassin, has botched up his latest kill, and might have to pay for it with his life. Assigned to kill a top British scientist who may be defecting to the Soviets with the answer to nuclear survival, he carries ot his mission flawlessly only to discover he's killed an imposter. The real Everett Langtree is alive and well in Poland. He still has to kill the traitor. Accompanied by Langtree's estranged daughter, he heads behind the Iron Curtain, knowing full well that he is committing suicide. Once they reach Poland and, later, Moscow, thrills and intrigue engulf Wilde and Lynn like the Russian snow, and he finds himself adrift in an enemy land minus the use of his only weapon--his deadly right hand. When a group of Russians offer him safe passage home if he will do a job for them, the results can only be his Wildest adventure yet.
