It’s not worth it. It sure as hell isn’t worth that, Jack told himself. He’d lost his parents to an airliner crash at Chicago, and remembered the sudden, wrenching loss, the impact that had come like a thrown punch. For all that, it had come with merciful speed. He hadn’t realized it at the time, but he did now. Ryan made a point of seeing Admiral Greer three times a week, watching his body shrink, draw in on itself like a drying plant, watching the pain lines deepen in his dignified face as the man fought valiantly in a battle he knew to be hopeless. He’d been spared the ordeal of watching his parents fade away, but Greer had become a new father to him, and Ryan was now observing his filial duty for his surrogate parent. Now he understood why his wife had chosen eye surgery. It was tough, technically demanding work in which a slip could cause blindness, but Cathy didn’t have to watch people die. What could be harder than this – but Ryan knew that answer. He’d seen his daughter hover near death, saved by chance and some especially fine surgeons.
Where do they get the courage? Jack wondered. It was one thing to fight against people. Ryan had done that. But to fight against Death itself, knowing that they must ultimately lose, but still fighting. Such was the nature of the medical profession.
Jesus, you’re a morbid son of a bitch this morning.
What would the Admiral say?
He’d say to get on with the goddamned job.
The point of life was to press on, to do the best you can, to make the world a better place. Of course, Jack admitted, CIA might seem to some a most peculiar place in which to do that, but not to Ryan, who had done some very odd but also very useful things here.
A smell got his attention. He turned to see that the coffee machine on the credenza was turned on. Nancy must have done it, he realized. But Admiral Greer’s mugs were gone, and some “generic” CIA-logoed cups sat on the silver tray. Just then came a knock on the door. Nancy’s head appeared.
“Your department-head meeting starts in two minutes, Dr. Ryan.”
“Thanks, Mrs. Cummings. Who did the coffee?” Jack asked.
“The Admiral called in this morning. He said you would need some on your first day.”
“Oh. I’ll thank him when I go over tonight.”
“He sounded a little better this morning,” Nancy said hopefully.
“Hope you’re right.”
The department heads appeared right on schedule. He poured himself a cup of coffee, offering the same to his visitors, and in a minute was down to work. The first morning report, as always, concerned the Soviet Union, followed by the others as CIA’s interests rotated around the globe. Jack had attended these meetings as a matter of routine for years, but now he was the man behind the desk. He knew how the meetings were supposed to be run, and he didn’t break the pattern. Business was still business. The Admiral wouldn’t have had it any other way.
With presidential approval, things moved along smartly. Overseas communications were handled, as always, by the National Security Agency, and only the time zones made things inconvenient. An earlier heads-up signal had been dispatched to the legal attaches in several European embassies, and at the appointed time, first in Bern, teletype machines operating off encrypted satellite channels began punching out paper. In the communications rooms in all the embassies, the commo-techs took note of the fact that the systems being used were the most secure lines available. The first, or register, sheet prepped the technicians for the proper one-time-pad sequence, which had to be retrieved from the safes which held the cipher keys.
For especially sensitive communications – the sort that might accompany notice that war was about to start, for example – conventional cipher machines simply were not secure enough. The Walker-Whitworth spy ring had seen to that. Those revelations had forced a rapid and radical change in American code policy. Each embassy had a special safe – actually a safe within yet another, larger safe – which contained a number of quite ordinary-looking tape cassettes. Each was encased in a transparent but color-coded plastic shrink-wrap. Each bore two numbers. One number – in this case 342 – was the master registration number for the cassette. The other – in the Bern embassy; it was 68 – designated the individual cassette within the 342 series. In the event that the plastic wrap on any of the cassettes, anywhere in the world, was determined to be split, scratched, or even distorted, all cassettes on that number series were immediately burned on the assumption that the cassette might have been compromised.
In this case, the communications technician removed the cassette from its storage case, examined its number, and had his watch supervisor verify that it had the proper number: “I read the number as three-four-two.”
“Concur,” the watch supervisor confirmed. “Three-four-two.”
“I am opening the cassette,” the technician said, shaking his head at the absurd solemnity of the event.
The shrink-wrap was discarded in the low-tech rectangular plastic waste can next to his desk, and the technician inserted the cassette in an ordinary-looking but expensive player that was linked electronically to another teletype machine ten feet away.
The technician set the original printout on the clipboard over his own machine and started typing.
The message, already encrypted on the master 342 cassette at NSA headquarters, Fort Meade, Maryland, had been further encrypted for satellite transmission on the current maximum-security State Department cipher, called STRIPE, but even if someone had the proper keys to read STRIPE, all he would have gotten was a message that read DEERAMO WERAC KEWJRT, and so on, due to the super-encipherment imposed by the cassette system. That would at the least annoy anyone who thought that he’d broken the American communications systems. It certainly annoyed the communications technician, who had to concentrate as hard as he knew on how to type things like DEERAMO WERAC KEWJRT instead of real words that made some sort of sense.
Each letter passed through the cassette player, which took note of the incoming letter and treated it as a number from 1 (A) to 26 (Z), and then added the number on the tape cassette. Thus, if 1 (A) on the original text corresponded to another 1 (A) on the cassette, 1 was added to 1, making 2 (B) on the clear-text message. The transpositions on the cassette were completely random, having been generated from atmospheric radio noise by a computer at Fort Meade. It was a completely unbreakable code system, technically known as a One-Time Pad. There was, by definition, no way to order or predict random behavior. So long as the tape cassettes were uncompromised, no one could break this cipher system. The only reason that this system, called TAPDANCE, was not used for all communications was the inconvenience of making, shipping, securing, and keeping track of the thousands of cassettes that would be required, but that would soon be made easier when a laser-disc format replaced the tape cassettes. The code-breaking profession had been around since Elizabethan times, and this technical development threatened to render it as obsolete as the slide rule.
The technician pounded away on the keyboard, trying to concentrate as he grumbled to himself about the late hours. He ought to have been off work at six, and was looking forward to dinner in a nice little place a couple of blocks from the embassy. He could not, of course, see the clear-text message coming up ten feet away, but the truth was that he didn’t give a good goddamn. He’d been doing this sort of thing for nine years, and the only reason he stuck with it was the travel opportunity. Bern was his third posting overseas. It wasn’t as much fun as Bangkok had been, but it was far more interesting than his childhood home in Ithaca, New York.
The message had seventeen thousand characters, which probably corresponded to about twenty-five hundred words, the technician thought. He blazed through the message as quickly as he could.
“Okay?” he asked when he was finished. The last “word” had been ERYTPESM.
“Yep,” the legal attaché replied.
“Great.” The technician took the telex printout he’d just typed from and fed it into the code room’s own shredder. It came out as flat pasta. Next he removed the tape cassette from the player and, getting a nod from the watch supervisor, walked to the corner of the room. Here, tied to a cable fixed to the wall – actually it was just a spiraled telephone cord – was a large horseshoe magnet. He moved this back and forth over the cassette to destroy the magnetic information encoded on the tape inside. Then the cassette went into the burn-bag. At midnight, one of the Marine guards, supervised by someone else, would carry the bag to the embassy’s incinerator, where both would watch a day’s worth of paper and other important garbage burned to ashes by a natural-gas flame. Mr. Bernardi finished scanning the message and looked up.
