James Cairncross followed Alan Turing to the little house near P Street. He watched as Turing went inside, and a few minutes later he had the proof he needed. He clearly saw the great Alan Turing
Cairncross was one of the remaining members of the Cambridge Five Soviet Spy ring. So far he had evaded detection and was working side by side with Allan Turing on a top-secret project. Alan had made a device that cracked the German and Japanese Enigma code. The machine had been destroyed after the last war. Because of Turing’s work, the war ended two to four years earlier than anticipated.
Cairncross knew a defection by Turing would greatly enhance the progress of the Soviets in making a rival calculating machine. Alan needed an environment that was conducive to the way he worked, and in the way he behaves around other people. He was sure Beria and Stalin could provide just what was required.
Alan had all the schematics for a new device in his head. Using electronic parts that other Soviet spies had smuggled out of the United States, Turing could easily create another. Such a machine would be invaluable to the spy network of the USSR and would eventually revolutionize mathematics and the world of code breaking. Cairncross was convinced that ultimately, these machines would go on to rival human beings.
First, Cairncross had to get Turing to commit to communism, or at least to renounce his British heritage. Alan’s defection might be possible if somehow, someone turned Turing into the police and he was prosecuted for sodomy. Such behavior so upset the British authorities that they were willing to put people in jail to stop it. The British penal system even gave men convicted of
Cairncross knew that the other four members of The Cambridge Five were also homosexuals. Their Soviet handlers didn't seem to mind that fact, so it made sense they might overlook Turing’s choices as well. He certainly hoped this was the case, because Alan Turing was a
The initial step was finding a policeman who could be persuaded to investigate Turing. Cairncross understood you have to do some investigating yourself to find the most likely candidate and somehow convince him to search the poor fellow’s apartment. You could easily plant some incriminating evidence to make the whole process go faster.
In talking with Alan, Cairncross determined that he was not political or a staunch nationalist. All he cared about was solving puzzles. His calculating machine would be the ultimate puzzle that would solve other ultimate puzzles. He doubted very much that Alan could resist the challenge. The choice was simple, jail and humiliation, or a lifetime of solving puzzles.
Cairncross was fairly confident Turing would make a decision that was favorable to the Communist cause. Alan Turing was the key to a communist victory. Now, all Cairncross had to do was to make Alan's past determine his future.
