Prime Suspect's mother looked at the police officers, sizing them up. This was her home. She would show the police to her son's room, as they requested, but she was not going to allow them to take over the whole house. As she tartly instructed the police where they could and could not go, she thought, I'm not standing for any nonsense from you boys.

`Where's your son?' one officer asked her.

`At a party.'

`What is the address?'

She eyed him warily. She did not like these officers at all. However, they would no doubt wait until her son returned anyway, so she handed over the address.

While the police swarmed though Prime Suspect's room, gathering his papers, computer, modem and other belongings, his mother waited in his doorway where she could keep an eye on them.

Someone knocked at the door. An AFP officer and Prime Suspect's mother both went to answer it.

It was the police—the state police.

The next-door neighbours had heard a commotion. When they looked out of their window they saw a group of strange men in street clothes brazenly taking things from the widow's home as if they owned the place. So the neighbours did what any responsible person would in the circumstances. They called the police.

The AFP officers sent the Victoria Police on their way. Then some of them set off in a plain car for the Vermont party. Wanting to save Prime Suspect some embarrassment in front of his friends, his mother rang him at the party and suggested he wait outside for the AFP.

As soon as Prime Suspect hung up the phone he tried to shake off the effect of a vast quantity of alcohol. When the police pulled up outside, the party was in full swing. Prime Suspect was very drunk, but he seemed to sober up quite well when the AFP officers introduced themselves and packed him into the car.

`So,' said one of the officers as they headed toward his home, `what are you more worried about? What's on your disks or what's in your desk drawer?'

Prime Suspect thought hard. What was in his desk drawer? Oh shit! The dope. He didn't smoke much, just occasionally for fun, but he had a tiny amount of marijuana left over from a party.

He didn't answer. He looked out the window and tried not to look nervous.

At his house, the police asked him if he would agree to an interview.

`I don't think so. I'm feeling a little … under the weather at the moment,' he said. Doing a police interview would be difficult enough. Doing it drunk would be just plain dangerous.

After the police carted away the last of his hacking gear, Prime Suspect signed the official seizure forms and watched them drive off in to the night.

Returning to his bedroom, he sat down, distracted, and tried to gather his thoughts. Then he remembered the dope. He opened his desk drawer. It was still there. Funny people, these feds.

Then again, maybe it made sense. Why would they bother with some tiny amount of dope that was hardly worth the paperwork? His nervousness over a couple of joints must have seemed laughable to the feds. They had just seized enough evidence of hacking to lock him up for years, depending on the judge, and here he was sweating about a thimbleful of marijuana which might land him a $100 fine.

As the late spring night began to cool down, Prime Suspect wondered whether the AFP had raided Mendax and Trax.

At the party, before the police had shown up, he had tried to ring Mendax. From his mother's description when she called him, it sounded as if the entire federal police force was in his house at that moment. Which could mean that only one other IS hacker had gone down at the same time. Unless he was the last to be raided, Mendax or Trax might still be unaware of what was happening.

As he waited for the police to pick him up, a very drunk Prime Suspect tried to ring Mendax again. Busy. He tried again. And again. The maddening buzz of an engaged signal only made Prime Suspect more nervous.

There was no way to get through, no way to warn him.

Prime Suspect wondered whether the police had actually shown up at Mendax's and whether, if he had been able to get through, his phone call would have made any difference at all.

The house looked like it had been ransacked. It had been ransacked, by Mendax's wife, on her way out. Half the furniture was missing, and the other half was in disarray. Dresser drawers hung open with their contents removed, and clothing lay scattered around the room.

When his wife left him, she didn't just take their toddler child. She took a number of things which had sentimental value to Mendax. When she insisted on taking the CD player she had given him for his twentieth birthday just a few months before, he asked her to leave a lock of her hair behind for him in its place. He still couldn't believe his wife of three years had packed up and left him.

The last week of October had been a bad one for Mendax. Heartbroken, he had sunk into a deep depression. He hadn't eaten properly for days, he drifted in and out of a tortured sleep, and he had even lost the desire to use his computer. His prized hacking disks, filled with highly incriminating stolen computer access codes, were normally stored in a secure hiding place. But on the evening of 29 October 1991, thirteen disks were strewn around his $700 Amiga 500. A fourteenth disk was in the computer's disk drive.

Mendax sat on a couch reading Soledad Brother, the prison letters from George Jackson's nine-year stint in one of the toughest prisons in the US. Convicted for a petty crime, Jackson was supposed to be released after a short sentence but was kept in the prison at the governor's pleasure. The criminal justice system kept him on a merry-go-round of hope and despair as the authorities dragged their feet. Later, prison guards shot and killed Jackson. The book was one of Mendax's favourites, but it offered little distraction from his unhappiness.

The droning sound of a telephone fault signal—like a busy signal—filled the house. Mendax had hooked up his stereo speakers to his modem and computer, effectively creating a speaker phone so he could listen to tones he piped from his computer into the telephone line and the ones which came back from the exchange in reply. It was perfect for using Trax's MFC phreaking methods.

Mendax also used the system for scanning. Most of the time, he picked telephone prefixes in the Melbourne CBD. When his modem hit another, Mendax would rush to his computer and note the telephone number for future hacking exploration.

By adjusting the device, he could also make it simulate a phreaker's black box. The box would confuse the telephone exchange into thinking he had not answered his phone, thus allowing Mendax's friends to call him for free for 90 seconds.

On this night, however, the only signal Mendax was sending out was that he wanted to be left alone. He hadn't been calling any computer systems. The abandoned phone, with no connection to a remote modem, had timed out and was beeping off the hook.

It was strange behaviour for someone who had spent most of his teenage years trying to connect to the outside world through telephone lines and computers, but Mendax had listened all day to the hypnotic sound of a phone off the hook resonating through each room. BEEEP. Pause. BEEEP. Pause. Endlessly.

A loud knock at the door punctured the stereo thrum of the phone.

Mendax looked up from his book to see a shadowy figure through the frosted glass panes of the front door. The figure was quite short. It looked remarkably like Ratface, an old school friend of Mendax's wife and a character known for his practical jokes.

Mendax called out, `Who is it?' without moving from the sofa.

`Police. Open up.'

Yeah, sure. At 11.30 p.m.? Mendax rolled his eyes toward the door. Everyone knew that the police only raid your house in the early morning, when they know you are asleep and vulnerable.

Mendax dreamed of police raids all the time. He dreamed of footsteps crunching on the driveway gravel, of shadows in the pre-dawn darkness, of a gun-toting police squad bursting through his backdoor at 5 a.m. He dreamed of waking from a deep sleep to find several police officers standing over his bed. The dreams were very disturbing. They accentuated his growing paranoia that the police were watching him, following him.

The dreams had become so real that Mendax often became agitated in the dead hour before dawn. At the close of an all-night hacking session, he would begin to feel very tense, very strung out. It was not until the computer disks, filled with stolen computer files from his hacking adventures, were stored safely in their hiding place that he would begin to calm down.

`Go away, Ratface, I'm not in the mood,' Mendax said, returning to his book.

The voice became louder, more insistent, `Police. Open the door. NOW'. Other figures were moving around behind the glass, shoving police badges and guns against the window pane. Hell. It really was the police!

Mendax's heart started racing. He asked the police to show him their search warrant. They obliged immediately, pressing it against the glass as well. Mendax opened the door to find nearly a dozen plain-clothes police waiting for him.

`I don't believe this,' he said in a bewildered voice `My wife just left me. Can't you come back later?'

At the front of the police entourage was Detective Sergeant Ken Day, head of the AFP's Computer Crimes Unit in the southern region. The two knew all about each other, but had never met in person. Day spoke first.

`I'm Ken Day. I believe you've been expecting me.'

Mendax and his fellow IS hackers had been expecting the AFP. For weeks they had been intercepting electronic mail suggesting that the police were closing the net. So when Day turned up saying, `I believe you've been expecting me,' he was completing the information circle. The circle of the police watching the hackers watching the police watch them.

It's just that Mendax didn't expect the police at that particular moment. His mind was a tangle and he looked in disbelief at the band of officers on his front step. Dazed, he looked at Day and then spoke out loud, as if talking to himself, `But you're too short to be a cop.'

Day looked surprised. `Is that meant to be an insult?' he said.

It wasn't. Mendax was in denial and it wasn't until the police had slipped past him into the house that the reality of the situation slowly began to sink in. Mendax's mind started to work again.
