TAKEOFF.
Five minutes later, the man who currently called himself Hadley Kra.s.sen was gazing down from one of the speeding dots in the westbound traffic corridor at ten thousand feet, Route 305, of the Omaha Traffic Area.
Over fourteen hundred miles away, in an office block in the center of San Francisco, the plaque on the door of one of the suites proclaimed it to be the registered business premises of J.J. MARSHALL, INDUSTRIAL FINANCIAL a.n.a.lYST. Inside, the offices all looked normal enough One room at the rear of the suite, however, was different. Inside it, four people-three men and a woman, all in their late twenties to late thirties-sat surrounded by an array of consoles, keyboards, and display screens amid a confusion of banks of electronic and computing equipment. Working in these cramped conditions over the previous five months, this team had penetrated the ”hyper-safe” integrated communications and database network of the NORAM Defense Department. That, of course, included the computers at Anderscliff.
From their room in San Francisco, the Martian Federation scientists could extract and alter any data in the Anderscliff system and monitor the operation of its most highly protected programs. Also, if they wished, they could insert into the system, and run, programs of their own devising-the personnel record for Kra.s.sen, Hadley B., had not found its way into the Anderscliff file system through the normal channels.
The woman noted a change in the pattern of symbols on one of the screens and keyed a command string into her console. Groups of numbers appeared in columns on another display.
”The call code and flight-profile data for his airmobile have just been received from air traffic control, along with detail of a bunch of other vehicles,” she announced.
One of the men behind her consulted another readout. ”They'll all be incoming flights,” he said. ”Morning commuters into Anderscliff. Area control is programming the local ground processors and approach radars at Anderscliff to handle the landing sequences.”
”He must be nearly there, then,” somebody commented.
The a.s.sa.s.sin gazed down at the expanding sprawl of office blocks, laboratory buildings, domes, storage tanks, and girder lattices, all tied together loosely by a triangle of roadways and pipelines, that made up the Joint Services Armaments Research Establishment. His vehicle was sinking toward a rooftop parking area, which he recognized as one of the staff parking zones from ground plans taken from satellite pictures; he had memorized it all thoroughly before leaving Mars.
The vehicle slowed as it descended, finally coming to hover thirty feet above the next available s.p.a.ce along one of the partially filled rows. The optical scanner presented a view of the landing spot, and he satisfied himself that the area was clear before okaying the computer to proceed with the final phase of landing.
Three minutes later, briefcase in hand, he was walking toward the rooftop entry gate and checkpoint, through which he would have to pa.s.s to enter the Establishment itself. He had timed his arrival to coincide with the morning rush. Ahead of him, a half dozen or so persons, some shouting morning greetings back and forth, were converging on the door that led in to the checkpoint. n.o.body took any notice of him as he tagged along behind two men talking shop in loud voices, and followed them through the doorway between two steel-helmeted guards.
Inside, the pair in front pa.s.sed their hand-baggage to an attendant behind a counter, who in turn pa.s.sed it through the hatch in the wall behind her for checking. The a.s.sa.s.sin followed suit. There was no sign of the spot body-searches for which he had been told to be prepared.
Following the still-chattering duo, he found himself in a short queue shuffling slowly forward toward a desk where pa.s.ses were being checked. Almost immediately, others lined up behind him. He watched the procedure being followed at the desk, searching for any subtle differences from what he had been briefed to expect. There were none. Whoever had been responsible for research for the a.s.signment had done a thorough job.
Avoiding eye contact with the security officer seated at the check-in desk, he stepped forward, extracted the magnetically coded name-tag from his pa.s.s folder, pushed it into the slot provided, and keyed the memorized check digits into the keyboard below. He then pressed his right thumb against the gla.s.s plate located next to the slot and recited aloud into the microphone above: ”Kra.s.sen, Hadley B. 7x8H/927380.BB.”
Elsewhere in the Establishment, a computer located the record and compared the check digits stored with the pa.s.s code against the sequence that had just been keyed in at the gate. They matched. The thumbprint and voiceprint profiles held in the record also matched those that had just been input.
”I don't know you, do I?” The security officer at the desk regarded him through narrowed eyes.
”Only started working here a coupla days ago.” The a.s.sa.s.sin's reply was in a matter-of-fact drawl. His face retained the deadpan stare of the early-morning riser not quite awake yet.
”Your pa.s.s folder, please.”
The a.s.sa.s.sin pa.s.sed the folder across and stood impa.s.sively while the officer ran his eye rapidly down the card, pausing to compare the photograph inside it with the features confronting him.
”Who's your boss?”
”Professor Henderson, Department 39, Plasma Physics.”
The security officer surveyed the column of illuminated signs on his console panel, all glowing POSITIVE for the computer checks, then nodded and pa.s.sed the folder back together with a plastic lapel badge.
”Okay. Hope you enjoy working at Anderscliff, Dr. Kra.s.sen.”
”Thank you.”
The a.s.sa.s.sin removed the magnetic name-tag from the slot in front of him, moved a few paces forward, and paused to insert it in the window of the lapel badge and fasten the badge to his jacket. Then he moved on to the counter beyond and retrieved his briefcase, checked and cleared.
For the first time in several minutes he allowed himself to relax a little, drawing in a long, slow breath and exhaling with it the worst of the tension that had built up inside him. He was in. He had penetrated the impenetrable. He knew of course that the real work had been done long before, and represented something like ten man-years of effort.
He took an elevator down to ground level and emerged from the building through a set of gla.s.s doors surmounting a flight of shallow steps, where he stopped for a while to study the geography of this part of the Establishment, especially the approaches to the building he had just come out of. Then, guided by his predeparture briefing and the direction signs about the Establishment, he made his way through the maze of buildings and up to the cafeteria on the third floor of the domestic block.
As he progressed from one area to another, detectors above the doorways through which he pa.s.sed picked up the signal being transmitted by the microcircuit in the lapel badge. The signal was unique to his pa.s.s code, controlled by the magnetic name-tag that he had inserted from his pa.s.s folder. Everybody in Anderscliff carried such a badge. All the signals picked up by all the detectors all over the Establishment were monitored by a surveillance computer which continuously compared them against stored tables of which pa.s.s codes authorized entry to any particular building, floor, section, or room. An attempt to violate the system of limited access would trigger an immediate alert. The surveillance system thus provided an automatic check of who was entering restricted areas and enabled reports to be printed out, if required, of who had been in any particular place on any given day and at what time.
The surveillance computer was not programmed to track the movements of an individual through the Anderscliff complex, although the data from the detectors would have enabled such a task to be accomplished quite easily. The designers of the system had not seen any purpose in such a function. But the Martian Federation scientists in San Francisco had. Accordingly, they had developed a program of their own that enabled them, from fourteen hundred miles away, to monitor the precise movements of both the a.s.sa.s.sin and his victim. They thus possessed all the information needed to guide him to his target.
He settled himself at an empty table by one wall of the cafeteria and consumed a leisurely cup of coffee, allowing the people who were still arriving time to disperse about the Establishment and settle down to their daily routines. After twenty minutes or so had pa.s.sed, he rose and walked back to the lobby to enter one of the three public infonet booths located near the door. The message waiting for him in the electronic dead-letter box read:
