She found that part of the tape and played it through to herself. The Grebulons, which is what they called themselves, were politely showing her which buttons they pressed to make the ship go.

'Yes, but what principle does it work on?' she heard herself demand, from behind the camera.

'Oh, you mean is it something like a warp drive or something like that?' they said.

'Yes,' persisted Tricia. 'What is it?'

'It probably is something of the kind,' they said.

'Like what?'

'Warp drive, photon drive, something like that. You'd have to ask the Flight Engineer.'

'Which one is he?'

'We don't know. We have all lost our minds, you see.'

'Oh yes,' said Tricia, a little faintly. 'So you said. Um, how did you lose your minds, exactly, then?'

'We don't know,' they said, patiently.

'Because you've lost your minds,' echoed Tricia, glumly.

'Would you like to watch television? It is a long flight. We watch television. It is something we enjoy.'

All of this riveting stuff was on the tape, and fine viewing it made. First of all the picture quality was extremely poor. Tricia didn't know why this was, exactly. She had a feeling that the Grebulons responded to a slightly different range of light frequencies, and that there had been a lot of ultra-violet around which was mucking up the video camera. There were a lot of interference patterns and video snow as well. Probably something to do with the warp drive that none of them knew the first thing about.

So what she had on tape, essentially, was a bunch of slightly thin and discoloured people sitting around watching televisions that were showing network broadcasts. She had also pointed the camera out of the very tiny viewport near her seat and got a nice, slightly streaky effect of stars. She knew it was real, but it would have taken a good three or four minutes to fake.

In the end she had decided to save her precious videotape for Rupert itself and had simply sat back and watched television with them. She had even dozed off for a while.

So part of her sick feeling came from the sense that she had had all that time in an alien spacecraft of astounding technological design, and had spent most of it dozing in front of reruns of M*A*S*H and Cagney and Lacey. But what else was there to do? She had taken some photos as well, of course, all of which had subsequently turned out to be badly fogged when she got them back from the chemist.

Another part of her sick feeling probably came from the landing on Rupert. This at least had been dramatic and hair-raising. The ship had come sweeping in over a dark and sombre landscape, a terrain so desperately far removed from the heat and light of its parent sun that it seemed like a map of the psychological scars on the mind of an abandoned child.

Lights blazed through the frozen darkness and guided the ship into the mouth of some kind of cave that seemed to bend itself open to accept the small craft.

Unfortunately, because of the angle of their approach, and the depth at which the small thick viewport was set into the craft's skin, it hadn't been possible to get the video camera to point directly at any of it. She ran through that bit of the tape.

The camera was pointing directly at the sun.

This is normally very bad for a video camera. But when the sun is roughly a third of a billion miles away it doesn't do any harm. In fact it hardly makes any impression at all. You just get a small point of light right in the middle of the frame, which could be just about anything. It was just one star in a multitude.

Tricia fast-forwarded.

Ah. Now, the next bit had been quite promising. They had emerged out of the ship into a vast, grey, hangar-like structure. This was clearly alien technology on a dramatic scale. Huge grey buildings under the dark canopy of the Perspex bubble. These were the same buildings that she had been looking at at the end of the tape. She had taken more footage of them while leaving Rupert a few hours later, just as she was about to reboard the spacecraft for the journey home. What did they remind her of?

Well, as much as anything else they reminded her of a film set from just about any low-budget science-fiction movie of the last twenty years. A lot larger, of course, but it all looked thoroughly tawdry and unconvincing on the video screen. Apart from the dreadful picture quality she had been struggling with the unexpected effects of gravity that was appreciably lower than that on Earth, and she had found it very hard to keep the camera from bouncing around in an embarrassingly unprofessional way. It was therefore impossible to make out any detail.

And now here was the Leader coming forward to greet her, smiling and sticking his hand out.

That was all he was called. The Leader.

None of the Grebulons had names, largely because they couldn't think of any. Tricia discovered that some of them had thought of calling themselves after characters from television programmes they had picked up from Earth, but hard as they had tried to call each other Wayne and Bobby and Chuck, some remnant of something lurking deep in the cultural subconscious they had brought with them from the distant stars which were their homes must have told them that this really wasn't right and wouldn't do.

The Leader had looked pretty much like all the others. Possibly a bit less thin. He said how much he enjoyed her shows on TV, that he was her greatest fan, how glad he was that she had been able to come along and visit them on Rupert and how much everybody had been looking forward to her coming, how he hoped the flight had been comfortable and so on. There was no particular sense she could detect of being any kind of emissary from the stars or anything.

Certainly, watching it now on videotape, he just looked like some guy in costume and make-up, standing in front of a set that wouldn't hold up too well if you leant against it.

She sat staring at the screen with her face cradled in her hands, and shaking her head in slow bewilderment.

This was awful.

Not only was this bit awful but she knew what was coming next. It was the bit where the Leader asked if she was hungry after the flight, and would she perhaps like to come and have something to eat? They could discuss things over a little dinner.

She could remember what she was thinking at this point.

Alien food.

How was she going to deal with it?

Would she actually have to eat it? Would she have access to some sort of paper napkin she could spit stuff out into? Wouldn't there be all sorts of differential immunity problems?

It turned out to be hamburgers.

Not only did it turn out to be hamburgers, but the hamburgers it turned out to be were very clearly and obviously McDonald's hamburgers which had been reheated in a microwave. It wasn't just the look of them. It wasn't just the smell. It was the poly– styrene clamshell packages they came in which had 'McDonald's' printed all over them.

'Eat! Enjoy!' said the Leader. 'Nothing is too good for our honoured guest!'

This was in his private apartment. Tricia had looked around it in bewilderment that had bordered on fear but had nevertheless got it all on videotape.

The apartment had a waterbed in it. And a Midi hi-fi. And one of those tall electrically illuminated glass things which sit on table tops and appear to have large globules of sperm floating about in them. The walls were covered in velvet.

The leader lounged against a brown corduroy bean bag and squirted breath-freshener into his mouth.

Tricia began to feel very scared, suddenly. She was further from Earth than any human being, to her knowledge, had ever been, and she was with an alien creature, who was lounging against a brown corduroy bean bag and squirting breath-freshener into his mouth.

She didn't want to make any false moves. She didn't want to alarm him. But there were things she had to know.
