Red Rabbit - Tom Clancy [52]
"Pad one-one-five-eight-nine-zero," he told the clerk behind the metal screen, handing off the paper slip. The clerk, a man of fifty-seven long years, most of them here, walked a few meters to fetch the proper cipher book. It was a loose-leaf binder, about ten centimeters across by twenty-five high, filled with punched paper pages, probably five hundred or more. The current page was marked with a plastic tag.
The pages looked like those in a telephone book, until you looked closely and saw that the letters didn't form names in any known language, except by random accident. There were on average two or three such occurrences per page. Outside Moscow, on the Outer Ring Road, was the headquarters of Zaitzev's own directorate, the Eighth, the part of KGB tasked with making and breaking codes and ciphers. On the roof of the building was a highly sensitive antenna which led to a teletype machine. The receiver that lay between the antenna and the teletype listened in on random atmospheric noise, and the teletype interpreted these "signals" as dot-dash letters, which the adjacent teletype machine duly printed up. In fact, several such machines were cross-connected in such a way that the randomness of the atmospheric noise was re-randomized into totally unpredictable gibberish. From that gibberish were made the one-time pads, which were supposed to be totally random transpositions that no mathematical formula could predict or, therefore, decrypt. The one-time-pad cipher was universally regarded as the most secure of encryption systems. That was important, since the Americans were the world leaders at cracking ciphers. Their "Venona" project had even compromised Soviet ciphers of the late 1940s and '50s, much to the discomfort of Zaitzev's parent agency. The most secure one-time pads were also the most cumbersome and inconvenient, even for experienced hands like Captain Zaitzev. But that couldn't be helped. And Andropov himself wanted to know how to get physically close to the Pope.
That's when it hit Zaitzev: Physically close to the Pope. But why would anyone want that? Surely Yuriy Vladimirovich didn't want anyone to hear his confession.
What was he being asked to transmit?
The Rome rezident, Goderenko, was a highly experienced field officer whose rezidentura operated many Italian and other nationals as agents for the KGB. He forwarded all manner of information, some overtly important, some merely amusing, though potentially useful in compromising otherwise important people with embarrassing foibles. Was it that only the important had such weaknesses, or did their positions merely allow them to entertain themselves in manners which all men dreamt about but few could indulge in? Whatever the answer, Rome would have to be a good city for it. City of the Caesars, Zaitzev thought, it ought to be. He thought of the travel and history books he'd read on the city and the era—classical history in the Soviet Union had some political commentary, but not all that much. The political spin applied to every single aspect of life was the most tiring intellectual feature of life in his country, often enough to drive a man to drink—which, in the
