megabyte of plain text each, a few dozen copies of underground make an extremely effective mail bomb.

That's a joke, folks, not a suggestion. ;-)

Like many of the people in this book, I'm not big on rules. Fortunately, there aren't many that come with this electronic version. Don't print the work on paper, CD or any other format, except for your own personal reading pleasure. This includes using the work as teaching material in institutions. You must not alter or truncate the work in any way. You must not redistribute the work for any sort of payment, including selling it on its own or as part of a package. Random House is a friendly place, but as one of the world's largest publishers it has a collection of equally large lawyers. Messing with them will leave you with scars in places that could be hard to explain to any future partner.

If you want to do any of these things, please contact me or my literary agents Curtis Brown & Co first. I retain the copyright on the work. Julian Assange designed the elegant layout of this electronic edition, and he retains ownership of this design and layout.

If you like the electronic version of the book, do buy the paper version. Why? For starters, it's not only much easier to read on the bus, its much easier to read full stop. It's also easier to thumb through, highlight, scribble on, dribble on, and show off. It never needs batteries. It can run on solar power and candles. It looks sexy on your bookshelf, by your bed and in your bed. If you are a male geek, the book comes with a girl-magnet guarantee. The paper version is much easier to lend to a prospective girlfriend. When she's finished reading the book, ask her which hacker thrilled her to pieces. Then nod knowingly, and say coyly `Well, I've never admitted this to anyone except the author and the Feds, but ..'

And the most important reason to purchase a paper copy? Because buying the printed edition of the book lets the author continue to write more fine books like this one.

Enjoy!

"But, how do you *know* it happened like that?" — Reader

Due of the seamless nature of `Underground' this is a reasonable question to ask, although hints can be found at the back of the book in the Bibliography and Endnotes. The simple answer to this question is that we conducted over a hundred interviews and collected around 40,000 pages of primary documentation; telephone intercepts, data intercepts, log-files, witness statements, confessions, judgements. Telephone dialog and on-line discussions are drawn directly from the latter. Every significant hacking incident mentioned in this book has reams of primary documentation behind it. System X included.

The non-simple answer goes more like this:

In chapter 4, Par, one of the principle subjects of this book, is being watched by the Secret Service. He's on the run. He's a wanted fugitive. He's hiding out with another hacker, Nibbler in a motel chalet, Black Mountain, North Carolina. The Secret Service move in. The incident is vital in explaining Par's life on the run and the nature of his interaction with the Secret Service. Yet, just before the final edits of this book were to go the publisher, all the pages relating to the Block Mountain incident were about to be pulled. Why?

Suelette had flown to Tuscon Az where she spent three days interviewing Par. I had spent dozens of hours interviewing Par on the phone and on-line. Par gave both of us extraordinary access to his life. While Par displayed a high degree of paranoia about why events had unfolded in the manner they had, he was consistent, detailed and believable as to the events themselves. He showed very little blurring of these two realities, but we needed to show none at all.

During Par's time on the run, the international computer underground was a small and strongly connected place. We had already co-incidentally interviewed half a dozen hackers he had communicated with at various times during his zig-zag flight across America. Suelette also spoke at length to his lead lawyer Richard Rosen, who, after getting the all-clear from Par, was kind enough to send us a copy of the legal brief. We had logs of messages Par had written on underground BBS's. We had data intercepts of other hackers in conversation with Par. We had obtained various Secret Service documents and propriety security reports relating to Par's activities. I had extensively interviewed his Swiss girlfriend Theorem (who had also been involved with Electron and Pengo), and yes, she did have a melting French accent.

Altogether we had an enormous amount of material on Par's activities, all of which was consistent with what Par had said during his interviews, but none of it, including Rosen's file, contained any reference to Black Mountain, NC. Rosen, Theorem and others had heard about a SS raid on the run, yet when the story was traced back, it always led to one source. To Par.

Was Par having us on? Par had said that he had made a telephone call to Theorem in Switzerland from a phone booth outside the motel a day or two before the Secret Service raid. During a storm. Not just any storm. Hurricane Hugo. But archival news reports on Hugo discussed it hitting South Carolina, not North Carolina. And not Black Mountain. Theorem remembered Par calling once during a storm. But not Hugo. And she didn't remember it in relation to the Black Mountain raid.

Par had destroyed most of his legal documents, in circumstances that become clear in the book, but of the hundreds of pages of documentary material we had obtained from other sources there was wasn't a single mention of Black Mountain. The Black Mountain Motel didn't seem to exist. Par said Nibbler had moved and couldn't be located. Dozens of calls by Suelette to the Secret Service told us what we didn't want to hear. The agents we thought most likely to have been involved in the the hypothetical Black Mountain incident had either left the Secret Service or were otherwise unreachable. The Secret Service had no idea who would have been involved, because while Par was still listed in the Secret Service central database, his profile, contained three significant annotations:

1. Another agency had ``borrowed'' parts Par's file. 2. There were medical ``issues'' surrounding Par. 3. SS documents covering the time of Black Mountain incident had been destroyed for various reasons that become clear the book. 4. The remaining SS documents had been moved into ``deep-storage'' and would take two weeks to retrieve.

With only one week before our publisher's ``use it or lose it'' dead-line, the chances of obtaining secondary confirmation of the Black Mountain events did not look promising.

While we waited for leads on the long trail of ex, transfered and seconded SS agents who might have been involved in the Black Mountain raid, I turned to resolving the two inconsistencies in Par's story; Hurricane Hugo and the strange invisibility of the Black Mountain Motel.

Hurricane Hugo had wreathed a path
