Trevor was pretending he didn’t know Carla. As instructed, he walked beside Nina, making a point of smiling and talking to her. The other tourists would automatically assume she was his mother.
Carla followed the others into the building. They bunched up at a second set of heavy glass doors that blocked access to the lobby proper. This inner entrance was manned by two more security guards. One stood on this side of the doors, directing the visitors to an automated flatscan camera that took each person’s picture, then spat out a laminated badge bearing the words VISITOR’S PASS and the date and time of the tour group’s arrival. The other guard stood on the far side of the glass door, looking on with a bored expression as visitors who were leaving the building dropped their passes into a machine that automatically scanned and counted them. Eventually it would strip the digital photographs and dates from the badges so that they could be reused.
When it was her turn, Carla smiled for the camera, then attached the pass it spat out to the lapel of her jacket by its metal clip. She followed the others through the inner doors and into the lobby itself.
The lobby had a floor of silvered metal that was etched with black in a pattern that resembled the circuitry of an old-fashioned silicon chip. Banks of escalators at the back of the lobby led up to the second and third floors, which housed the Byte of the Future displays. Each had a balcony from which visitors could look down at the patterned lobby floor.
The other floors of the skyscraper-and the offices they contained-were accessed by entrances elsewhere in the building, rather than from this lobby. Mitsuhama encouraged the general public to view its displays, but took a dim view of them wandering through its office space.
As she stepped onto the escalator, Carla could hear Trevor, behind her now, talking excitedly to Nina about the new SimSea exhibit. She allowed herself a small sigh of relief. The kid was playing his part to the hilt, making sure everyone noticed that he and Nina were together, and frequently calling her “Mom.”
Carla had been on this tour two years ago when doing an entertainment feature on a new series of games Mitsuhama had developed. It had been a fun piece; she’d strapped on the headset and was instantly transported into the cockpit of a fighter ship that was rocketing its way between the stars. They’d even gotten the feeling of zero-G right.
On that occasion, Carla had been an invited guest. This time, she would be a trespasser-no better than a shadowrunner. And Mitsuhama would be doing its best to evict her-by any means necessary.
The Byte of the Future display was tucked into a series of rooms that opened onto the second- and third-floor balconies. Dozens of adults and children moved back and forth from one display room to another, filling the air with their awed laughter. Behind the babble of voices, games beeped and chimed, automated announcements described the static displays and robotic vehicles whined and hummed.
The three Mitsuhama employees who’d been assigned to guide the 5 p.m. tour were waiting on the second floor. They did not wear formal uniforms, but all were garbed in corporate colors: blue slacks and a white shirt. Carla wore the same thing under her jacket.
Out of the three guides who would be leading the five o’clock tour, two were Asian. Mitsuhama might talk about being an equal-opportunity employer, but when you scanned the employee records-as Corwin had done earlier-the truth became clear. The corp showed a clear preference for hiring humans of Japanese descent.
As they split the tourists into three groups, Carla joined the group that would be led by a woman who was of approximately the same build as herself. Thanks to the cosmetic surgery that had given Carla’s face a Native American appearance, she could pass for Japanese-or, at least, for a Eurasian of Japanese descent.
She’d be a close enough match for the picture on the woman’s employee ID badge.
Carla kept to the back of the group as the hour-long tour began. The first stop was an exhibit of oversized, boxy computers from the late twentieth century. All of the machines were in working order, and each had an adapter that allowed it to access the Matrix in a clunky, glacially slow fashion. The exhibit showed the gradual advances in the computer industry, and concluded with an exhibit of the latest direct neural interface technology-all of it, naturally, designed and built by Mitsuhama.
Pretending to examine one of these state-of-the-art computers, Carla fished the datachip out of her pocket and slotted it into one of the multi-ports at the back of the deck. The program on it had been hurriedly designed, that very afternoon, by Corwin. Precisely one hour after it was installed, it would write itself onto the virtual memory of this computer. It would then execute in the background, uploading itself to the display hall’s central processing unit while it was running its batch maintenance programs. The system’s operator might notice a slight stutter in the computer, but would probably pass it off as a hardware sequencing problem.
From there, the program would find its way onto the slave nodes that served the Byte of the Future display and would drop, without a trace, the name Lucifer. It would then be only a matter of time-hopefully no more than a few minutes, but certainly no more than an hour-before the spirit dove into the Matrix again and was drawn like an angry hornet to those nodes, corrupting the programs as it sought to eliminate the files containing its name. When that happened, the system that ran the display area would crash. Every computer-controlled display, lighting panel, and climate-control device in the Byte of the Future exhibit would shut down. And that would provide just the distraction Carla needed.
After exiting the display of antique computers, the group wound its way through a variety of exhibits: autonomously guided vehicles currently being used in the Mars exploration program; war simulators used to train monotank drivers; simsense walk-throughs of CAD/CAM do-it-yourself architectural programs; animated-cartoon holograms that described the development of ASIST (emphasizing the minor role Mitsuhama had played in its development); and a gigantic, two-story-tall mockup of an optical data-storage and retrieval system. The kids loved that one; they got to slide through strobing tubes, pretending they were individual photons of light. By either bunching together or going singly, they could duplicate the pulses by which data was encoded and could trigger different sounds and holo images. Each group of children erased the data of the group who’d preceded them, writing their own combination.
Carla smiled. It was a bit prophetic, somehow.
The final stop on the tour was a large room that held a wide array of booths that displayed Mitsuhama’s latest simsense games. Here, the members of the tour group were first warned that they had to meet back at the bus at six o’clock, sharp, then were turned loose to spend the last fifteen minutes of their tour playing with the interactive displays.
It was time for Carla to make her move. Winding her way through the people who crowded the room, she nodded at Nina and stepped into one of the simsense booths. It was a multi-user display; there were enough headsets for six people to interact with the program at once. Fortunately, no one else joined them in the booth.
Carla handed Nina her badge. “You remember what to do, don’t you?”
The ork girl smiled. “Null perspiration, chummer. I just gotta drop it in the box.”
Carla winced. Like her boyfriend, Nina had the habit of using Street slang, despite her education. She took Nina’s badge and slipped it into her pocket. “Good,” she said. “Off you go, then.”
As Nina stepped out of the booth, Carla focused on the digital display in the corner of her cybereye’s field of view. It was nearly six o’clock. Time for her tour group to make its way back to the bus. And for Corwin’s program to start doing its thing.
