Tommy Hambledon is sent to rescue Kaspar, the young boy who is king-in-hiding of a small European nation that has been subsumed by the USSR. But when Tommy gets there he finds that Kaspar has been taken to a distant school intended to turn out the future leaders of Russia. By devious means, Tommy ingratiates himself with the leaders of the Russian secret police, the M.V.D., and gets himself sent to the town where Kaspar's school is located. Eventually, Tommy and Kaspar make their harrowing escape from the USSR. A fascinating look at the state of Berlin and Russia before the Berlin Wall was constructed.
