It had been infuriating to see her that way. He had wanted to jerk her to her feet and shake her, to make that wonderful, uncomplicated anger come rushing upward to meet him. But he hadn't. If he gave in to those urges, he would lose his control once and for all, and he never wanted to do that.

What he did want to do, more than anything else in the world, was storm over to her quarters and make love to her so hard and so long that when it was over she would know she belonged to him. Maybe it wouldn't solve any of this, but it would sure as hell make him feel better. But he couldn't do that, either. Seeing her at all would knock down the last critical brick behind which he had dammed up his temper, releasing a flood of emotion that would sweep him away along with everything else.

Caroline lay on top of the covers on her narrow mattress, too listless to crawl between the sheets and actually go to bed. Such a normal action was beyond her. She had showered and dressed for bed, but she couldn't even go through the motions of pretending to sleep. All she could do was lie there in the silent darkness and stare at the ceiling. She could feel her heart beating, feel the slow, rhythmic expansions of her rib cage as she breathed. Those actions said that she still lived, but she didn't feel alive. She felt numb, dead inside.

By now they would have talked to Cal, who would have verified that she'd been telling the truth. Joe would know that he'd been wrong, but somehow that didn't give her any satisfaction. Still, she had expected at least a phone call from either him or Captain Hodge, to say "Sorry, we made a mistake." Surely they wouldn't be stupid enough to think she was resting and would rather they wait until morning to tell her.

Or Cal could have lied.

She couldn't deny the possibility. The thought had slipped into her consciousness not long after she had lain down on the bed. If she hadn't been so upset, it might have occurred to her earlier. It was the natural progression of the line of thought she had been following earlier in the hangar, when she had been staring at the laser pod and sorting out the various ways in which what had happened could have happened.

Cal was a whiz with computers. He was the one who had found that minor glitch on Friday, but only when Caroline had begun nosing around the computer. She hadn't thought anything of it then, but if he had tampered with the commands, he wouldn't have wanted her to really concentrate on the program. He knew she had a degree in computer science, because they had talked shop on several occasions. And on both Friday and today-yesterday, now, since it was past midnight-he had really looked exhausted. From being up all night? Cal was normally as bouncy as a rubber ball.

And Cal was the only other person who had touched her ID tag. Maybe he had picked it up on Thursday when she'd lost it and had left when she had so that the sensors would match the number of warm bodies leaving with the number of ID cards. She hadn't known the sensors monitored those leaving the buildings, too, but maybe Cal had; after all, he'd been working here from the beginning and noticed things like that, while she tended to pay attention only to what directly concerned her job.

Even if he had used her ID tag to regain entrance to the building Thursday night, she knew he hadn't had it on Sunday night.

But how easily could they be duplicated? He would have had to leave the base to get it done, but she was certain it was possible. After all, the sensors had said she had reentered the work area at midnight, which would have given him several hours to have a copy made.

Then she had called him on Friday morning asking him to search the office for her tag, which had given him the perfect opportunity to return it to her and keep security from being notified. Otherwise he wouldn't have been able to use the card again, because security would have removed that particular code from the computers.

She stopped her thoughts and rubbed her forehead, trying to force everything into making sense. If her call for help had been pure chance, then there wouldn't have been any reason for him to have had the card duplicated. Had he played the odds that she would call him? They were good odds, she had to admit. She wouldn't have called Yates, and she certainly wouldn't have wasted her tune calling Adrian. It was also a good bet that she wouldn't have wanted to call security. Not a certainty, but good enough that it wasn't much of a risk, either.

So what had happened then? The sensors showed both her and Cal entering the building, then both leaving. He must have had her card on him where the sensor could read it, thereby establishing proof that he hadn't had the opportunity to tamper with the computer program because he hadn't been in there alone. But why hadn't the sensor noticed that there were two cards but only one body?

Maybe the sensors weren't as good as Captain

Hodge obviously liked to believe they were. Maybe they were programmed to catch people without cards, but no one had thought to program it to catch cards without people. Maybe Cal had figured out a way to fool it. There were a lot of maybes, all of them possible. As good as he was with computers, maybe he had somehow gotten into the base computers and logged her both in and out of the building that morning. She didn't know and might never find out.

But what would Cal do now, if he were guilty? If the programs had been tampered with, he would know that analysis would discover it. Would he try to get back into the program and cover his tracks by undoing what he had done, hoping that the analysis wouldn't go any further than a simple comparison? Or would he try to plant more evidence against her?

She had to go with the second option. It was so much more feasible. Why would Cal go to so much trouble only to undo it? No, as long as the finger was pointing toward her, he would be smart to try to make certain it remained pointing in that direction.

Her heart suddenly began thundering in her chest. If Cal were guilty, if he were going to do anything else, he would have to do it tonight, while things were still in an upheaval. Given enough tune, the security net would settle down so tightly that nothing would be able to escape, but there were still windows of opportunity when things first started happening.

She knew the entire laser team was being restricted from the work area, but had their bar codes already been deleted from the computers? The military worked a lot like big business when it came to office work: most of it was done during the day. Since the restriction order had only been issued that night, had Captain Hodge called in someone to enter it into the computer or left it to be done first thing in the morning? Knowing human nature, she would bet on the latter. After all, she was the only one under suspicion, and she was probably under surveillance in the interim.

On a hunch she rolled out of bed and silently walked to the small, old-fashioned crank-out window set high in the wall in the kitchen area. She had to stand on a chair to see out of it. Sure enough, a security police car was parked on the opposite side of the street. In the glow of the streetlight she could plainly see two men in the front seat. They were making no effort to disguise their purpose, but then, why should they? This wasn't clandestine surveillance, but plain old guard duty.

There was no other door.

There was, however, another high, narrow window in the bedroom. In the almost total darkness she carefully made her way back to the bedroom and stared at the small oblong of light in the wall. A man certainly couldn't get through there, and she had doubts that she could, either. Nevertheless, she stood on the bed and peeped out. That side of the street was empty.

Well, there was no point in putting herself to a lot of trouble if Cal was peacefully sleeping in bed. She mustn't let herself forget that he might be totally innocent, that he had indeed verified her story. Innocent until proven guilty was the law of the land, though
