We returned to Quantico shortly after three, and when I tried to reach Wesley, he was not in. I left a message for him to find me at ERF, where I planned to spend the next few hours with my niece.

No engineers or scientists were on her floor because it was a holiday weekend, and we were able to work alone and in quiet.

'I could definitely get global mail out,' Lucy said, sitting at her desk. She glanced at her watch. 'Look, why not just throw something out there and see who bites?'

'Let me try the chief from Seattle again.'

I had his number on a slip of paper and called it. I was told he had left for the day.

'It's very important that I reach him,' I explained to the answering service. 'Perhaps he can be reached at home?'

'I'm not at liberty to give that out. But if you'll give me your phone number, when he calls in for his messages…'

'I can't do that,' I said as my frustration grew. 'I'm not at a number he can call.' I told her who I was, adding, 'What I'm going to do is give you my pager number. Please have him call me and then I'll call him.'

That didn't work. An hour later my pager remained silent.

'She probably didn't get it straight about putting pound signs after everything,' Lucy said as she cruised around inside CAIN.

'Any strange messages anywhere?' I asked.

'No. It's a Friday afternoon and a lot of people are on holiday. I think we should send something out over Prodigy and see what comes back.'

I sat next to her.

'What's the name of the group?'

'American Academy of Gold Foil Operators.'

'And their highest concentration is Washington State?'

'Yes. But it can't hurt to include the entire West Coast.'

'Well, this will include the entire United States,' Lucy said as she typed Prodigy and entered her service ID and password. 'I think the best way to do this is through the mail.' She pulled up a Jump Window. 'What do you want me to say?' She looked over at me.

'How about this? To all American Academy of Gold Foil Operators. Forensic pathologist desperately needs your help ASAP. And then give them the information to contact us.'

'All right. I'll give them a mailbox here and carbon copy it to your mailbox in Richmond.' She resumed typing. 'The replies may come in for a while. You may find you get a lot of dentists for pen pals.'

She tapped a key as if it were a coda and pushed back her chair. 'There. It's gone,' she said. 'Even as we speak, every Prodigy subscriber should have a New Mail message. Let's just hope someone out there is playing with their computer and can help.'

Even as she spoke, her screen suddenly went black, and bright green letters started flowing across it. A printer turned on.

'That was quick,' I started to stay.

But Lucy was out of her chair. She ran to the room where CAIN lived and scanned her fingerprint to get in. Glass doors unlocked with a firm click and I followed her inside. The same writing was flowing across the system monitor, and Lucy snatched a small beige remote control off the desk and pressed a button. She glanced at her Breitling and activated the stopwatch.

'Come on, come on, come on!' she said.

She sat before CAIN, staring into the screen as the message flowed. It was one brief paragraph repeated numerous times. It said:

— - -MESSAGE PQ43 76301 001732 BEGINS- - -TO: - All COPS FROM: - CAIN

— - -MESSAGE PQ43 76301 001732 ENDS- - -

I looked at the shelves of modems filling one wall, at lights flashing. Though I was not a computer expert, I saw no correlation between their activity and what was occurring on screen. I looked around some more and noticed a telephone jack below the desk. A cord that was plugged into it disappeared beneath the raised floor, and I found that odd.

Why would a device plugged into a telephone jack be stored beneath a floor? Telephones were on tables and desks. Modems were on shelves. I got down and lifted a panel that covered a third of the floor inside CAIN's room.

'What are you doing?' Lucy exclaimed, unable to take her eyes off the screen.

The modem beneath the floor looked like a small cube puzzle with rapid flashing lights.

'Shit!' Lucy said.

I looked up. She stared at her watch and wrote something down. The activity on the screen had stopped. The lights on the modem quit flashing.

'Did I do something?' I asked in dismay.

'You bastard!' She pounded her fist on the desk, and the keyboard jumped. 'I almost had you. One more time and I would have had your ass!'

I got up. 'I didn't disconnect anything, I hope?' I said.

'No. Dammit! He logged off. I had him,' she said, still staring at her monitor as if the green words might begin to flow again.

'Gault?'

'CAIN's imposter.' She blew out a big breath of air and looked down at the naked guts of the creation she had named after the world's first murderer. 'You found it,' she blandly said. 'That's pretty good.'

'That's how he's been getting in,' I said.

'Yes. It's so obvious no one noticed.'

'You noticed.'

'Not at first.'

'Carrie put it there before she left last fall,' I said.

Lucy nodded. 'Like everybody else, I was looking for something more technologically recondite. But it was brilliant in its simplicity. She hid her own private modem and the dial-in is the number of a diagnostics line almost never used.'

'How long have you known?'

'As soon as the weird messages started, I knew.'

'So you just had to play the game with him,' I said, upset. 'Do you realize how dangerous this game is?' I asked.

She began typing. 'He tried it four times. God, we were close.'

'For a while you thought Carrie was doing this,' I said.

'She set it up, but I don't think she's the one getting in.'

'Why not?'

'Because I've been following this intruder day and night. This is someone unskilled.' For the first time in months, she spoke her former friend's name. 'I know how Carrie's mind works. And Gault's too narcissistic to let anyone be CAIN except him.'

'I got a note, possibly from Carrie, that was signed CAIN,' I said.

'And I'll bet Gault didn't know she mailed it. And I'll also bet that if he found out, he took that little pleasure away from her.'

I thought of the pink note we suspected Gault had spirited away from Carrie at Sheriff Brown's house. When Gault placed it in the pocket of the bloody pajama top, the act certainly served to reassert his dominance. Gault would use Carrie. In a sense, she always waited in the car except when he needed her help to move a body or perform a degrading act.

'What just happened here?' I said.

Lucy did not look at me when she answered, 'I found the virus and have planted my own. Every time he tries to send a message to any terminal connected to CAIN, I have the message replicate itself on his screen - like it's bouncing back in his face instead of going out anywhere. And he gets a prompt that says Please Try Again. So he tries again. The first time this happened to him, the system icon gave him a thumbs-up after two tries, so he thought the message was sent.

'But when he tried the next time, the same thing happened, but I made him try one additional time. The point is to keep him on the line long enough for us to trace the call.'

'Us?'

Lucy picked up the small beige remote control I had seen her grab earlier. 'My panic button,' she said. 'It goes via radio signal straight to HRT.'

'I assume Wesley has known about this hidden modem since you discovered it.'

'Right.'

'Explain something to me,' I said.

'Sure.' She gave me her eyes.

'Even if Gault or Carrie had this secret modem and its secret number, what about your password? How could either of them log on as a superuser? And aren't there UNIX commands you could type that would tell you if another user or device was logged on?'

'Carrie programmed the virus to capture my username and password whenever I changed them. The encrypted forms were reversed and sent to Gault via E-mail. Then he could log on as me, and the virus wouldn't let him log on unless I was logged on, too.'

'So he hides behind you.'

'Like a shadow. He's used my device name. My same username and password. I figured out what was going on when I did a WHO command one day and my username was there twice.'

'If CAIN calls users back to verify their legitimacy, why hasn't Gault's telephone number shown up on ERF's monthly bill?'

'That's part of the virus. It instructs the system on callbacks to bill the call to an AT amp;T credit card. So the calls never showed up on the Bureau's bills. They show up on the bills of Gault's father.'

'Amazing,' I said.

'Apparently, Gault has his father's phone card number and PIN.'

'Does he know his son has been using it?'

A telephone rang. She picked it up.

'Yes, sir,' she said. 'I know. We were close. Certainly, I will bring you the printouts immediately.' She hung up.

'I don't think anyone's told him,' Lucy said.

'No one here has told Peyton Gault.'

'Right. That was Mr. Wesley.'

'I must talk to him,' I said. 'Do you trust me to take him the printouts?'

Lucy was staring at the monitor again. The screen saver had come back on, and brilliant triangles were slowly slipping through and around each other like geometry making love.

'You can take it to him,' she said, and she typed Prodigy. 'Before you go… Wow, you've got new mail waiting.'

'How much?' I moved closer to her.

'Oops. Just one so far.' She opened it.

It read: What is gold foil?

Lucy said, 'We're probably going to get a lot of that.'

Sally was working the front desk again when I walked into the Academy lobby, and she let me through without the bother of registration and a visitors' pass. I walked with purpose down the long tan corridor, around the post office and through the gun cleaning room. I will always love the smell of Hoppes Number 9.

A lone man in fatigues was blasting compressed air into the barrel of a rifle. Rows of long black countertops were bare and perfectly clean, and I thought of years of classes, of the men and women I had seen, and of the times I had stood at a counter cleaning my own handgun. I had watched new agents come and go. I had watched them run, fight, shoot and sweat. I had taught them and cared.
