Tanner's Twelve Swingers by Lawrence Block
Evan Michael Tanner is 34 years old and hasn't slept a wink since a piece of shrapnel destroyed the sleep centre in his brain during the Korean War.
In a moment of drunken sentiment, Tanner had made an absurd promise to a friend - sure he'd smuggle himself into the Soviet Union, find his friend's long lost love and then smuggle them both back to the U.S....but the long-lost love - she had a sister. And the sister - she had these ten girlfriends, the sexiest Olympic team the Russians had ever sent to the Games.......but how do you smuggle all these people out of Russia? You don't - unless you create a little diversion, like suddenly spinning the world towards the brink of international war....
