Blind Run — Brian Freemantle

Imprisoned for treason, Charlie Muffin hunts for a way out - by crossing a line.

After a trumped-up trial, Charlie Muffin lands in jail for treason - ready to learn the secrets of his fellow inmate, a convicted British traitor. Nobody expected KGB agents to stage a prison break to free their man. Charlie faces another choice: go to Moscow to complete his assignment or face 40 long years in prison. It doesn't take him long to decide.

Charlie doesn't have the full picture, of course, which is the way of espionage. But Charlie doesn't regret his Iron Curtain escape, as it leads him to Natalia Fedova, the KGB interrogator assigned to determine if his defection is genuine or staged. For anyone else, the risk would be suicidal. But for Charlie, the greatest danger may be falling in love.
