No, she decided. I have to do it because it's something he doesn't want people to know about—doesn't want me to know about. It's worth something to him, and if I can crack it and copy it, then maybe I have a bargaining chip. Something that will help me make a deal to get out of here safely.

Also, I'm tired of being kept in the dark.

When the tea was ready and her hands were steadier she took the cup and returned to the chair and small table she had set up in one corner of the loft. She could hear people laughing on the street below, music blaring from cars. She reflected wistfully on how much nicer it would be if she had been born a sensible young woman, someone who would be out with friends on a Saturday night instead of sitting in a silent loft with black-out curtains on the windows, playing caretaker to a moody, violent bastard like Dread.

She took a sip of tea and stared at her pad screen. Whatever password Dread was using had resisted every attempt. It was infuriating, almost unbelievable. A password? Even the most garbled collection of numbers and letters should eventually roll up as a combination on her random character generator, but for some reason it hadn't happened. And now that she had found a new bit of back-alley crypto gear to sniff out the shape of the password—nine characters—it was even more frustrating that she couldn't solve it.

In fact, it almost seemed impossible. Nine characters! It only took a short time for the gear to go through every possible combination of letters, numerals, and punctuation marks, but again and again it came up with nothing that would open the door to Dread's metaphorical locked room.

Remembering the lab tape and the strange, blurred experiment footage, she had also tried every variant on what she felt sure was his name, John Wulgaru. The gear should have generated the same things randomly as part of its algorithm, but she could not help feeling certain that the things he kept so scrupulously hidden, like his name and background, would have some connection to other things he wanted to keep secret from the world, for instance this bit of mysterious storage. But his name had not provided the key either, and before Dread had so unexpectedly and alarmingly interrupted her she had been inputting names from Aboriginal mythology, even though they too should already have been created by the near-infinite patience of the crypto gear.

Dulcie stared at the pad, then back at Dread's supine form, his dark Buddha face. It didn't make sense. Nine characters, but she had worked on it for hours without result. There was something she was missing—but what?

On a hunch, she went looking in her toolbox for a piece of gear she didn't often use, a strange little tangle of code even more esoteric than the one which had determined how many characters were in the password. A Malaysian hacker with whom she occasionally did business had traded it to her for a set of Asian bank personnel files she had downloaded while assisting a hostile takeover that ultimately failed. The would-be corporate pirates had been jailed in Singapore, and one of them had even been executed. Dulcie had made sure she would never be connected with the incident, but she hadn't been paid either, so she had been happy to unload the files anonymously and get something for them.

The bit of code she had received in return, which her Malaysian friend had called "Stethoscope," was not the most broadly employable piece of gear she'd ever owned, but it had its uses. What it did best was to locate extremely small changes in processing speed—things that would never show up at the interface level of the system, but which could be used to discover potential bugs before they became larger problems. Not being in the gear-creation business, Dulcie had never used it for its intended purpose, but she had occasionally found it useful for locating flaws in the security of systems she wished to attack. She hadn't used it for almost a year before the Australia trip but it had proved very handy during Dread's incursion into the Grail system. Now something—hacker's intuition, perhaps—suggested it might serve a purpose again.

Because there has to be something else going on, Dulcie told herself as she put Stethoscope to work.

She started up the random-character generator again so the gear would have something to analyze, then sat back to sip her tea. She had almost forgotten the bolt of fear that had shot through her when Dread had burst shouting onto her screen. Almost.

Three minutes later the character-generation cycle had finished, as unsuccessfully as it had the other two dozen times. She opened the Stethoscope report and felt her heart quicken. There was something, or it certainly looked that way: a small hesitation, a minute hitch, as though Dread's system security had paused for a moment. Which, she guessed, meant that the security program had seen part of what it wanted, done a check, not found whatever else it needed to open access, and rebuffed the overture.

Dulcie bit her lip, thinking. It had to be some kind of double password—first X, then Y. But if the generator had given a prompt for the second password? Why hadn't the system stopped and waited? No human being could input fast enough to cough up another password in that microsecond of hesitation, even if it was spoken instead of typed.

Spoken. The back of her neck prickled. She checked Dread's system and felt a glow of triumph when she discovered, as she had guessed, that the audio input was turned off. That was it. The second password was supposed to be spoken after the first had been typed. The system had heard the first, checked for audio and found it disabled, so it had treated the whole thing as a failed attempt, all of this happening in a flash of time too small to be perceived by human senses.

She turned the audio on, reminding herself to be damn sure to turn it off again when she was finished—otherwise she might as well leave Dread a note saying she had been trying to hack his system—and began to patch together some modifications, hooking the character generator to the Stethoscope gear. When the hesitation came this time, the character generator would stop to be read, which should at least give her the first password.

She took another sip of tea, barely tasting it, then set the generator to work—in her mind's eye it was a roulette wheel, spinning so fast as to be almost invisible. In less than a minute it stopped, the letters "DREAMTIME" blinking in the log-in box. She recognized the word from her brief survey of Aboriginal mythology and felt a flush of triumph. This time, with the audio enabled, the system had recognized the first password and was waiting for the second.

But it's not going to wait very long, she suddenly realized, and the glow of victory faded. It's going to give me ten seconds, or twenty at the most, then it's going to shut off unless I say the right word. And the next time, or the time after that, when I don't give the right password, it's going to shut down for good—cut off all access, maybe even set off an alarm. It will certainly leave a damn clear mark that someone tried to get in.

She could never come up with the second password off the cuff, could think of nothing to try except "Wulgaru," which still seemed too obvious. And she could not generate could generate characters directly to the system, not even if she modified the character generator—which would take days anyway, maybe weeks of work in an area she knew almost nothing about.

Ten seconds gone. "DREAMTIME" still blinked on her screen, mocking her, but any moment now the window would close. She had worked so hard to solve the first part of the puzzle, but even though she had done it, she was stuck, fooled, foiled.

"Son of a bitch!" she said feelingly.
