Chapter 6: Sheyda, Sophie and Jessica

With the rest of the staff working over at the hospital to get the Taubett up and running, Cassie and Julie had the department to themselves. Eve spent most days working at her apartment, and only came into the uni for meetings.

Stefan began sending Julie data from the scanner in the USA by the end of that first week.

This seemed remarkably fast to Julie, but there were many problems with the initial data sets.

The first scans were only of small regions of the body. The Taubett could only image one section of the body at a time, and a full scan would have to be stitched together from many pieces. The stitching work had not yet been done.

There were also unresolved problems with imaging bone, because bone absorbs X-rays so strongly, so those first scans only showed fat, muscle, veins and connective tissue.

There were still a few dead sensor pixels, too, and these had yet to be processed out of the images.

Julie was immediately engrossed. Despite all of the problems, the quality of these initial scans was brilliant, with individual muscle fibres and capillaries visible in each slice.

She had been given three data sets to start with, of clean women, cured women, and infected women.

Under the Taubett, the infected women stood out a mile. Their muscles were infiltrated by the worm's nerve fibres, which glowed in the 250keV radiation in fine, silvery threads. Before the Taubett came along, nobody had seen this before: neither transmission X-rays nor the TSA's back-scatter machines had the resolution to show these fine details, and the TSA's back-scatter X-rays could only image the surface of the skin.

The cured women were not at all obvious in the scans. Julie could see some evidence of the channels where the worms' fibres had been. However, after a worm was removed, Eve had told them that the fibres were absorbed by the body, not leaving much evidence behind.

Cassie and Julie spent hours looking at those first results.

Julie was thinking about how she might be able to emphasise the evidence of a previous worm infection.

Cassie was imagining what it might feel like to have all of those nerve fibres running through one's body, subverting the nervous system, bending one's will to an alien intelligence.

Fascinating, Cassie thought.

Although Julie was excited to be getting good results so quickly, Cassie had been busy, too, and seemed to have about a dozen chat windows on her screen.

"So what are you doing, Cassie?" asked Julie. "I thought you were supposed to be interviewing cancer patients?"

Cassie hesitated for a moment, then made a decision.

"Jules," Cassie said, "Eve told me not to discuss my work with you.

"I don't trust her. She seems to think that we might get into some kind of battle of egos if you found out I had some real work to do.

"I'm chatting to cured women in the FEMA camp in Nevada.

"I'm trying to develop a test to detect worm infection. Eve saw the results I was getting with that toxoplasmosis test, and wants me to do tests for cured and infected women, using a standardised personality test."

Cassie continued,

"I'm sorry, Julie, but, basically, Eve accused you of being an arrogant, frigid, bitch, and told me to keep my work away from you."

Julie looked surprised.

The she looked hurt.

Then she cackled.

"Ha-ha. Well, no flies on Miss Eve. She got that part right, at least. I am an arrogant, frigid, bitch.

"But I also know all of Cassie Grayndler's innermost secrets

"I bet you'd like to join them, hey Cassie? Chat to them, real close, about what it was like to be possessed by worms? What it was like to have your mind controlled by aliens? What it was like to be forced to infect other women?"

Cassie laughed, embarrassed, and demurred, not very convincingly.

Of course, Julie was right.

Julie looked on as Cassie chatted, and was a little disappointed. It was just normal stuff between strangers on the Internet, getting to know each other, talking about their school-work, their accommodation, their room-mates.

"I have to be careful when I talk." Cassie explained. "Everything that we say is monitored, probably by the NSA."

After a while of watching them chat, Julie started to notice something a little odd.

"That woman is so polite, Cassie. She's absolutely charming. That's just not normal!"

"That's Eve's kid sister, Lilli," Cassie said. "Yeah, human kindness is real spooky, I know. But she's a Yank, Julie. She's nothing like you or me. And, also, I expect she knows what's at stake here.

"She's stuck in a poxy FEMA camp, and the NSA is spying on her and listening to everything she says. I have to be careful what I say, as I don't know what they'll be looking for. Those women have no way out.

"It sucks, Jules. I don't know what we can do.

"Eve seems to think that if we can show that their brains are normal then they have a chance of getting released."

Julie contemplated this for a little while, and came to the same conclusion as Cassie.

"If they pass the test," Julie said, "that's no proof that their brains are normal.

"It only proves that they're able to fake the test, or that the test isn't testing the right things.

"If Eve really wants to get her kid sister out of Nevada, she won't want you coming up with a test which shows that her brain has been altered by the worms. She'll want a test that shows her to be totally normal. Even if you come up with a good test, Cassie, it could be that Eve's just going to pass it on to her sister, or even on to all of the women."

Julie stared out into space for a while, seemingly deep in thought.

"It would be pretty easy to cheat," Julie said, "I think you could build a bit of insurance into your test, Cassie.

"Let's add a little watermark to your data. Before you give Eve your results, let's just perturb all of the statistics for the answers, very slightly, with some random numbers. Those random numbers form a kind of watermark.

"If someone cheats by making up a set of answers using your measurements, they'll pass your test, but we can still use a correlation test to detect the watermark. If you have a lot of questions, say, a hundred or so, you don't need much of a watermark to see if they cheated. Using a correlation test to detect random numbers is amazingly sensitive."

Cassie thought the idea sounded completely impractical.

Who would go to the trouble of making up a bunch of answers to match some complicated statistics, and then memorise a hundred answers before taking the test? Every person who wants to cheat would have to make up a new set of answers, too.

However, Cassie admired Julie's devious mind, and couldn't resist putting something over Eve, however impractical.

"Sounds great," Cassie said, "I'll add in the watermark. But you've got to write the cheat detector, and you can write the code for processing the test scores, too."

Julie nodded, half-heartedly, and agreed,

"Ok, Cassie, no worries," but she was distracted by what was on her screen.

There was something in the Taubett scans that looked familiar to her.

She brought up the image of one of the phantoms, taken on the Taubett machine when it was next door.

This was the machine that was now at Lennox Hospital.

She compared it against one of the new images, supposedly from the new machine in the USA, and flipped between the images several times.

She had been right.

When she flipped between the two images, the dead pixels remained exactly the same.

These scans had both been taken on the same machine.

She brought Cassie over to show her the results.

"Cassie," Julie said, "there's no way these images were taken in Baltimore.

"These images of infected women were taken on the machine at Lennox Hospital.

"I think we must have a whole lot of worm-infected women right here in Canberra."

Julie spent the next few weeks fixing up her visualisation software to work with the Taubett scans, and had started working on the worm-trail detection.

Both Cassie and Julie had a meeting scheduled with Eve the next morning to give her a status report.

Julie was pleased with her work so far. The old worm-channels were very narrow, so finding evidence of a past worm infection was difficult, but her visualisations of infected women were looking very nice.

Cassie spent the time sending out standard personality tests to the two groups selected by Eve: one of cured women, and one of normal women selected as controls. The cured women were like troopers, answering every question, and never failing to send back a survey. The normal women were intransigent, and kept stuffing up the answers, and with each new survey, a few would always drop out altogether.

Cassie couldn't decide if the cured women were unnaturally conscientious, or if they felt they owed their lives to Eve and her institution.

However, the test results were pretty clear. The cured women were very different from normal women. There was no way that these women could possibly pass for normal.

Eve's not going to like this, Cassie thought to herself.

She put all of the survey results into a spreadsheet, and only added Julie's watermark to the normal women's results as a kind of afterthought.

The idea of cheating sounded a little ludicrous. There would be no way that anyone could learn how to answer the questions like a normal person, as they'd need to do a lot of calculations in their head, and would need to make up random numbers to get the statistics to come out correctly.

Humans are notoriously bad at such things.

Eve was already in her office, apparently working hard, when Cassie and Julie knocked on her office door at 8:30 the next morning.

"Good morning girls. Welcome to our first official project meeting.

"Are there any problems? How is everything going?"

"No problems, Eve." Julie said. "I'm enjoying the work, it's proceeding well."

"Ditto," said Cassie, "we're actually starting to get some great results already."

Cassie presented first, showing Eve all the results she'd gathered so far.

"As you can see," said Cassie, "we can pick out the cured women very easily from the normal women. All of the cured women are nearly two standard deviations away from the norm, and I expect that with more sensitive analysis, the difference will become even more apparent."

Cassie didn't mention the watermark.

As Cassie had predicted, Eve didn't like these results very much, and she sat, tight-lipped, throughout the entire presentation.

When Cassie had finished, Eve didn't make any comments. She asked for a copy of the results, and asked Julie to commence her presentation.

Julie pulled out a folder, and laid out some printouts of images from her programs.

The silvery skeins of worm fibres were clearly visible in the muscle tissue.

"Eve, this Taubett data is of a very high quality, as you can see."

Julie pointed out the trails, but this was unnecessary, as they were bright and clear, and Eve looked very, very pleased.

Julie finally asked what had been on her mind.

"Eve, how did you get this data? I know for a fact that these scans were done in Canberra. Australia's quarantine regulations are supposed to keep the worms out. There aren't supposed to be any infected women here, yet here's a scan, showing clear evidence of a worm infection.

"Where are you keeping the infected women?"

For a good ten seconds, all Eve could do was stare at Julie.

She was livid.

She looked at both Julie and Cassie, in obvious disgust.

"Julie. Cassie. I don't want to tell you this again.

"The Taubett machine has been working in Baltimore for a few days now. I have had your colleagues working very hard to process the data, and the high quality of these images is a testament to their programming skills.

"There are no worms in Australia.

"Australian Customs border controls are more than sufficient to keep them out.

"I never want to hear such unfounded allegations in this building again, or anywhere else.

"Julie, your results are absolutely brilliant. You are obviously an an asset to my team. You're well on the way to showing the after-effects of a worm infection, I am sure.

"Cassie, I know you'd like to spend all day with Julie, and chatting with my sister.

"But you've completely ignored your NDA, and have deliberately disobeyed my instructions.

"You haven't done a lick of work with our cancer patients. I suggest that you get yourself over to the hospital today to begin planning your other interviews.

"Julie, I suggest that you should get over there, too, as soon as possible. You should stay up to date with the progress that Stefan and his colleagues are making on the Taubett data.

"Good work, Julie. Please continue.

"And, Cassie, I know you have a lot of potential. Don't squander it."

"I'm a little busy today, so I'll have to ask you to leave now."

Both Julie and Cassie scuttled out, feeling chastened.

A man in a suit was waiting outside Eve's office.

He looked familiar.

He caught Julie's eye, and reached for her hand.

"Julie Smith?"

Julie was still feeling cross with Eve, and greeted him, quite brusquely.

"Yes, nice to meet you." Julie said, "And who might you be?"

He didn't seem offended.

"Oh, don't worry about me, I'm not important. I'm just paying Eve Hunter a courtesy call."

"And Cassie Grayndler, too."

Cassie nodded her head, and he shook hands with her, too, and passed them both a card from his jacket pocket.

"I've taken a tour of the new hospital," he said, "and what Ms. Hunter and Dr Kelly have done for cancer treatment in this country is nothing short of astonishing.

"We all have high hopes for your work. Things are looking a bit dicey at the moment, so please give Eve your very best. The future of the new clinic needs to be sorted by the end of the year, and I'm sure you understand that there is a lot at stake."

Eve was holding the door open for him.

He gave Cassie and Eve a mischievous wink, and a smile, which they could see, but Eve could not.

Such a simple gesture managed to convey so much.

I'd rather stay and chat, but I'd best go through

The High and Mighty Miss Eve Hunter doesn't like to be kept waiting, does she?

I think I'd better humour her.

He bid them farewell,

"I'm so glad to have met you both. Bon chance, Julie. Bon chance, Cassie," and, without a trace of disrespect, greeted Eve with a smile.

"Good morning, Eve,"

Eve looked severely at Cassie and Julie as he walked into her office, and she closed the door.

Cassie read the card that had been passed to her.

They should have recognised him; he was John Landers, the Federal Minister for Health.

Cassie had only ever seen him before on television. He was pushing fifty, but looked remarkably fit and healthy.

She also remembered his twin daughters, Sophie and Jessica, with some distaste, as they'd been horrible to her at Uni.

But she also remembered them with sympathy. At their graduation, three years ago, they'd already been showing symptoms of early-onset Huntington's.

Horrible disease.

They were probably dead by now.

Maybe that explained why he'd become Minister for Health; he must have spent a lot of time in hospitals.

Cassie still felt quite pissed off at Miss Eve as she rode towards the hospital, helmeted head down and strong legs pedalling fast.

She had been working hard, and was already getting some definite results. The results weren't the ones that Eve wanted, and wouldn't help the cause of the cured women at all, but that wasn't Cassie's fault. She wasn't going to make up data for Eve's benefit, and, in any case, that wouldn't even work, as Cassie imagined that US government agencies were doing the same as Cassie.

These women were not normal, that was clear, but there were all sorts of problems with analysing the survey data. These women were Americans, from many different backgrounds, and, being stuck in musty trailers in Nevada, they were all eager for something to do which might help their circumstances.

It was no wonder they seemed odd.

Now she had to go and talk to cancer patients about their "feelings". She had hoped that her "official" work would remain just as words on her paper job description, never to be examined or worried about ever again.

The cancer survey would not be hard work, as she had learned all kinds of interviewing techniques in her background reading for toxoplasmosis, and for her Ph.D.

However, it was going to be pretty boring.

Depressing, too, as she knew that the prognosis for these patients was very poor.

Some of the women she talked to at the hospital were likely to die before the year was out.

Julie had piked out, of course, Cassie thought, She didn't like hospitals much.

Parking and locking her bike, Cassie unclipped her helmet and wandered into the new cancer ward.

She was a bit taken aback by the scanners. The hospital had been built with American money. Did all US hospitals have metal detectors now? Or was this a TSA scanner, set up to find something more interesting?

Eve had instructed Cassie to talk to Doctor Kelly, and Cassie hoped she wouldn't have to spend much time with any patients today.

The doctor was waiting for her, and greeted Cassie in a friendly way, and ushered her through the twisty little corridors of the building. They both took the lift up to Doctor Kelly's office on the top floor, and Cassie was impressed by its size.

Doctor Kelly sat behind her desk, and motioned Cassie to sit down in front of the desk.

"I've been hoping that you would pay us a visit," said Doctor Kelly. "I know that cancer may not be your chief interest here, but I'm very enthusiastic about the new treatment. It has been having amazing effects on the patients.

"When you've settled in, I'd like to find out what your impressions are about the project, and you're welcome to ask any questions."

Cassie wondered about Eve Hunter.

Neither Cassie nor Julie had ever had a normal conversation with Eve. She was so overbearing, they had both been swept along by her energy, but Cassie didn't know a thing about her.

And Cassie was still angry with her. In their first meeting, Cassie had felt very close to Eve, and had felt seduced. In the second meeting, Eve had turned upon her. Unfairly, too, Cassie thought.

Cassie realised then that she was still very angry.

"Doctor Kelly, who is Eve Hunter? She's doesn't seem like an academic, but she has a very senior position here. What's her role at Johns Hopkins?"

Doctor Kelly considered her reply carefully.

"Cassie, our Eve Hunter is a bit of a mystery woman.

"We had an outbreak of the worms in Baltimore, and were holding a few infected women in the hospital for tests. At that stage, we hadn't been told anything about the worms, and we were having a hard time getting close to them without risking our nurses.

"I only became involved because we wanted to try radiotherapy to kill the worms in-situ. It was a stupid idea in retrospect, but it was a measure of how desperate we had become, and the US government was throwing money at worm researchers.

"Eve Hunter turned up on our doorstep unannounced, bearing a patent application and a vial of vaccine which she said was a cure for the infection.

"Normally we'd reject such lone inventors out of hand, but Eve Hunter was very special. Her knowledge of the worms was exceptional, her patent application was convincing, and, somehow, she had discovered that we were holding infected women.

"Injecting one of the infected women with an unknown vaccine was a huge risk, but even then we knew what the likely future was for these women.

"That is to say, no future at all.

"After we saw the results, we knew that Eve was sitting on a goldmine.

"Eve came out right at the start and agreed to split the profits fifty-fifty if we would promote her vaccine.

"Every country in the world has purchased supplies of the vaccine she developed. The patent has been worth tens of millions of dollars to Johns Hopkins, and, of course, to Eve Hunter.

"We have both benefited immeasurably from her discovery, but I still have no idea where she came from, or how she funded the development of the vaccine in the first place.

"I've always assumed that she comes from old money in Boston, but everything she does is directed at getting the cured women released, and on saving her sister.

"She's using that money to promote her pet projects, which you and Julie know about of course.

"She has also been instrumental in getting Johns Hopkins to fund the cancer clinic here. I was very lucky to be chosen to direct it. The new treatment is actually extremely effective. You cannot imagine how gratifying it is to for an oncologist to be able to help all of her patients."

Cassie hesitated, but then made a decision.

After Eve's outburst, she wasn't hopeful, but she was still angry enough to be direct with Doctor Kelly.

Nothing ventured, nothing gained...

"Doctor Kelly, Julie and I have been looking at the Taubett data from Baltimore, the scans of infected women. But Julie says that the data must have come from the machine in this hospital, and we've seen images showing clear evidence of live worm infections.

"We believe that you must have infected women here. What are black thread-worms doing in Australia? I have to say, it sounds highly dangerous, and it's probably a criminal offence, right? What's going on here?"

Doctor Kelly beamed at Cassie, not a reaction she had expected.

"You and Julie are pretty special, did you know that? You are both very perceptive. Eve does choose her colleagues well.

"Yes, Cassie, we do have worms here, of course we do.

"They cure cancer, Cassie. The worms cure cancer.

"The worms are very effective in looking after their hosts, and are able to manipulate DNA to remove mutations and damage. They cure cancer, they kill bacterial infections, they fix congenital problems, they heal damage. Dozens of women are alive today who would otherwise be dead because of the worms, these women are healthier than they've ever been before. The worms are lifesavers, Cassie, and my job is to save lives. This is the most important advance in medicine since the introduction of antibiotics!"

Cassie was impressed, but she still felt a sense of disquiet. The idea was so crazy that she couldn't resist being a little flippant.

"Doctor Kelly, the worms are an alien race that wants to enslave humanity. Don't you think that your new treatment might not be a little risky?"

Doctor Kelly smiled, but humoured her.

"Yes, Cassie, of course. It's true, the worms did come here in an attempt to invade and conquer our planet, and our species.

"You know, they came pretty close to achieving their goal.

"But we have analysed all of the risks, and have managed these risks, and they are negligible. We have impenetrable security at all entrances to the hospital, with every person entering and leaving the hospital being automatically examined by a backscatter X-ray machine.

"We've mastered the worms now.

"We've come to a kind of truce.

"Any intelligent being knows that it's better to live in servitude than to die in a ditch. The worms accept their role as humanity's helpers, and, if they behave, there will be many more clinics like this one, and a comfortable life for them. If they don't behave, they know that they will not be allowed to survive.

"We have made an arrangement with the Australian government to run this one small clinic to cure inoperable cancer cases. Your security services have made arrangements to keep us all safe, and we are in complete agreement with their methods."

Cassie thought that everything sounded somewhat dubious, but she nodded her head. After all, she didn't have anything personal against the worms. Indeed, she couldn't help reminding herself, she rather liked them and what they could do, but that was all in fantasy, right? She wouldn't really want Earth taken over by an alien species, would she?

"I can see that Eve has got under your skin." Doctor Kelly said. "She can be abrasive, but that's because she is so single-minded. This clinic wouldn't be here without her. Please, give her a chance.

"I know you've had a tough time dealing with the women in the FEMA camps. They're not in the best of circumstances, and they're desperately trying to appear normal, to get out of that place.

"Your work would be a lot easier if you could work face to face, with Australians, with people like the people you know. I can arrange interviews with women in the clinic so you can work on your methods.

"If you can find any trace of the worms left behind, Eve will want to know about it.

"Now, Cassie, so you know what you're getting into, would you like to come in to the inner sanctum, to see the infected women? We could organise a regular time for you to interview any of the women here. We'll introduce you to the hosts as well. I'm sure you will find the work here far more pleasurable than you expected."

Cassie surprised herself by being ecstatic at this prospect. With the prospect of meeting the worms, her foul mood had lifted immediately. She had been given permission to meet representatives of an alien race, and the women who were held in thrall by them. She wanted to know how they felt about that, for sure, and what they were feeling.

"Of course," said Cassie, "I've done all the preparation I need. I'm ready to start work straight away."

"That's great," said Doctor Kelly. "Now, Cassie, I must impress upon you the need for absolute secrecy. Nobody must talk about our worms outside this building. You cannot even talk to Julie about this, although you are welcome to bring her here to see for herself what we are doing.

"Have I made myself clear?"

Cassie nodded.

That part was going to be hard.

"I'll just call Gabby to get you started on a tour."

Doctor Kelly made a quick phone call.

Gabby.

Cassie wasn't looking forward to seeing Gabby.

Cassie had always been quite open about her sexuality, and everyone at Uni knew about it. Likewise, Gabby had made no secret of how uncomfortable Cassie's sexuality made her feel, and had told Cassie so, to her face.

But Gabby still kept making overtures of friendship to Julie, as if Cassie simply did not exist, and, all this time, Gabby had been firm friends with Joan Pellman.

Joan dealt in drugs, and was as much of a Lesbian as Cassie, more so if you were counting conquests. Joan had spent most of second year trying to seduce Gabby, but Gabby simply had not noticed. Joan was friends with Cassie, too, and kept her supplied with dope, but Joan had somehow managed to keep her friendships with Gabby and Cassie completely separate.

Although Gabby was well on the path to becoming a brilliant scientist, Cassie thought her clueless and insensitive, even malicious.

Gabby soon appeared, and her signature woollen coat was nowhere to be seen.

She was looking very well. Extremely well, in fact. Her limp had disappeared, her skin had cleared up, and she was standing straighter than ever before.

The star piercing in her nose finally suited her.

Gabby no longer looked like a nerd wanting to look cool; in fact, she seemed extremely attractive.

"Hi, Cassie. Come with me, and I'll load you up with everything you need, then I'll show you around."

Gabby took Cassie by the hand, and gave it a squeeze.

Cassie was surprised at this small show of affection, but smiled, and squeezed back.

Why was Gabby being so friendly? Actually, why was she being super-friendly?

"Cassie, you're welcome to spend as much time as you like at the hospital." Gabby said. "You can spend nights here while you're doing interviews, if you like. There are spare beds in every ward here, the Hospital is not yet at full capacity.

"We've all been introduced to the infected women. I just need to help you make some preparations before your first visit. The infected women are lovely, of course, but you can't go in there without protection."

They had taken a lift to the first floor, where the administrative offices were, and walked to the end of a long corridor. Gabby opened the door, and motioned Cassie in.

"Pens, paper. You'll need these too."

Cassie now had a bag full of stationery, a desk on the first floor, and a computer. A laminated strip with her name on it had already been created to put on her desk. She had a view across the lake to the university, and there was a microwave link on the roof which connected her to the Uni network, so she'd be able to do her work here, just as if she were sitting at her desk at Uni.
