The name CARDINAL was known in Washington only to the top three CIA executives. On the first day of each month a new code name was chosen for his data, a name made known only to the highest echelon of CIA officers and analysts. This month it was WILLOW. Before being passed on, grudgingly, to outsiders, CARDINAL data was laundered as carefully as Mafia income to disguise its source. There were also a number of security measures that protected the agent and were unique to him. For fear of cryptographic exposure of his identity, CARDINAL material was hand delivered, never transmitted by radio or landline. CARDINAL himself was a very careful man—Penkovskiy's fate had taught him that. His information was conveyed through a series of intermediaries to the chief of the CIA's Moscow station. He had outlived twelve station chiefs; one of these, a retired field officer, had a brother who was a Jesuit. Every morning the priest, an instructor in philosophy and theology at Fordham University in New York, said mass for the safety and the soul of a man whose name he would never know. It was as good an explanation as any for CARDINAL's continued survival.

Four separate times he had been offered extraction from the Soviet Union. Each time he had refused. To some this was proof that he'd been turned, but to others it was proof that like most successful agents CARDINAL was a man driven by something he alone knew—and therefore, like most successful agents, he was probably a little crazy.

The document Ryan was reading had been in transit for twenty hours. It had taken five for the film to reach the American embassy in Moscow, where it was delivered at once to the station chief. An experienced field officer and former reporter for the New York Times, he worked under the cover of press attaché. He developed the film himself in his private darkroom. Thirty minutes after its arrival, he inspected the five exposed frames through a magnifying glass and sent a FLASH-priority dispatch to Washington saying that a CARDINAL signal was en route. Next he transcribed the message from the film to flash paper on his own portable typewriter, translating from the Russian as he went. This security measure erased both the agent's handwriting and, by the paraphrasing automatic to translation, any personal peculiarities of his language. The film was then burned to ashes, the report folded into a metal container much like a cigarette case. This held a small pyrotechnic charge that would go off if the case were improperly opened or suddenly shaken; two CARDINAL signals had been lost when their cases were accidentally dropped. Next the station chief took the case to the embassy's courier-in-residence, who had already been booked on a three-hour Aeroflot flight to London. At Heathrow Airport the courier sprinted to make connections with a Pan Am 747 to New York's Kennedy International, where he connected with the Eastern shuttle to Washington's National Airport. By eight that morning the diplomatic bag was in the State Department. There a CIA officer removed the case, drove it immediately to Langley, and handed it to the DCI. It was opened by an instructor from the CIA's technical services branch. The DCI made three copies on his personal Xerox machine and burned the flash paper in his ashtray. These security measures had struck a few of the men who had succeeded to the office of the DCI as laughable. The laughs had never outlasted the first CARDINAL report.
