"Sure, I'll be here," said the girl. "So how much is a lot?"

"Fifteen years' back pay."

"For?"

"Writing two words."

"Zarquon," said the girl. "Which one took the time?"

"The first one. Once I'd got that the second one just came one afternoon after lunch."

A huge electronic drum kit hurtled through the window high above them and smashed itself to bits in the street in front of them.

It soon became apparent that some of the burglar alarms on the next block had been deliberately set off by one police tribe in order to lay an ambush for the other. Cars with screaming sirens converged on the area, only to find themselves being picked off by copters which came thudding through the air between the city's mountainous tower blocks.

"In fact," said Ford, having to shout now above the din, "it wasn't quite like that. I wrote an awful lot, but they just cut it down."

He took his copy of the Guide back out of his satchel.

"Then the planet got demolished," he shouted. "Really worthwhile job, eh? They've still got to pay me, though."

"You work for that thing?" the girl yelled back.

"Yeah."

"Good number."

"You want to see the stuff I wrote?" he shouted. "Before it gets erased? The new revisions are due to be released tonight over the net. Someone must have found out that the planet I spent fifteen years on has been demolished by now. They missed it on the last few revisions, but it can't escape their notice for ever."

"It's getting impossible to talk isn't it?"

"What?"

She shrugged and pointed upwards.

There was a copter above them now which seemed to be involved in a side skirmish with the band upstairs. Smoke was billowing from the building. The sound engineer was hanging out of the window by his fingertips, and a maddened guitarist was beating on his fingers with a burning guitar. The helicopter was firing at all of them.

"Can we move?"

They wandered down the street, away from the noise. They ran into a street theatre group which tried to do a short play for them about the problems of the inner city, but then gave up and disappeared into the small restaurant most recently patronized by the pack animal.

All the time, Ford was poking at the interface panel of the Guide. They ducked into an alleyway. Ford squatted on a garbage can while information began to flood over the screen of the Guide.

He located his entry.

"Earth: Mostly harmless."

Almost immediately the screen became a mass of system messages.

"Here it comes," he said.

"Please wait," said the messages. "Entries are being updated over the Sub-Etha Net. This entry is being revised. The system will be down for ten seconds."

At the end of the alley a steel grey limousine crawled past.

"Hey look," said the girl, "if you get paid, look me up. I'm a working girl, and there are people over there who need me. I gotta go."

She brushed aside Ford's half-articulated protests, and left him sitting dejectedly on his garbage can preparing to watch a large swathe of his working life being swept away electronically into the ether.

Out in the street things had calmed down a little. The police battle had moved off to other sectors of the city, the few surviving members of the rock band had agreed to recognize their musical differences and pursue solo careers, the street theatre group were re-emerging from the pasta restaurant with the pack animal, telling it they would take it to a bar they knew where it would be treated with a little respect, and a little way further on the steel grey limousine was parked silently by the kerbside.

The girl hurried towards it.

Behind her, in the darkness of the alley, a green flickering glow was bathing Ford Prefect's face, and his eyes were slowly widening in astonishment.

For where he had expected to find nothing, an erased, closed-off entry, there was instead a continuous stream of data-text, diagrams, figures and images, moving descriptions of surf on Australian beaches, Yoghurt on Greek islands, restaurants to avoid in Los Angeles, currency deals to avoid in Istanbul, weather to avoid in London, bars to go everywhere. Pages and pages of it. It was all there, everything he had written.

With a deepening frown of blank incomprehension he went backwards and forwards through it, stopping here and there at various entries.

"Tips for aliens in New York:

Land anywhere, Central Park, anywhere. No one will care, or indeed even notice.

Surviving: get a job as cab driver immediately. A cab driver's job is to drive people anywhere they want to go in big yellow machines called taxis. Don't worry if you don't know how the machine works and you can't speak the language, don't understand the geography or indeed the basic physics of the area, and have large green antennae growing out of your head. Believe me, this is the best way of staying inconspicuous.

If your body is really weird try showing it to people in the streets for money.

Amphibious life forms from any of the worlds in the Swulling , Noxios or Nausalia systems will particularly enjoy the East River , which is said to be richer in those lovely life-giving nutrients then the finest and most virulent laboratory slime yet achieved.

Having fun: This is the big section. It is impossible to have more fun without electrocuting your pleasure centres..."

Ford flipped the switch which he saw was now marked "Mode Execute Ready" instead of the now old-fashioned "Access Standby" which had so long ago replaced the appallingly stone-aged "Off".

This was a planet he had seen completely destroyed, seen with his own two eyes or rather, blinded as he had been by the hellish disruption of air and light, felt with his own two feet as the ground had started to pound at him like a hammer, bucking, roaring, gripped by tidal waves of energy pouring out of the loathsome yellow Vogon ships. And then at last, five seconds after the moment he had determined as being the last possible moment had already passed, the gently swinging nausea of dematerialization as he and Arthur Dent had been beamed up through the atmosphere like a sports broadcast.

There was no mistake, there couldn't have been. The Earth had definitely been destroyed. Definitely, definitely. Boiled away into space.

And yet here - he activated the Guide again - was his own entry on how you would set about having a good time in Bournemouth, Dorset, England, which he had always prided himself on as being one of the most baroque pieces of invention he had ever delivered. He read it again and shook his head in sheer wonder.

Suddenly he realized what the answer to the problem was, and it was this, that something very weird was happening; and if something very weird was happening, he thought, he wanted it to be happening to him.

He stashed the Guide b

ack in his satchel and hurried out on to the street again.

Walking north he again passed a steel grey limousine parked by the kerbside, and from a nearby doorway he heard a soft voice saying, "It's OK, honey, it's really OK, you got to learn to feel good about it. Look at the way the whole economy is structured ..."

Ford grinned, detoured round the next block which was now in flames, found a police helicopter which was standing unattended in the street, broke into it, strapped himself in, crossed his fingers and sent it hurtling inexpertly into the sky.

He weaved terrifyingly up through the canyoned walls of the city, and once clear of them, hurtled through the black and red pall of smoke which hung permanently above it.

Ten minutes later, with all the copter's sirens blaring and its rapid-fire cannon blasting at random into the clouds, Ford Prefect brought it careering down among the gantries and landing lights at Han Dold spaceport, where it settled like a gigantic, startled and very noisy gnat.

Since he hadn't damaged it too much he was able to trade it in for a first class ticket on the next ship leaving the system, and settled into one of its huge, voluptuous body-hugging seats.

This was going to be fun, he thought to himself, as the ship blinked silently across the insane distances of deep space and the cabin service got into its full extravagant swing.

"Yes please," he said to the cabin attendants whenever they glided up to offer him anything at all.

He smiled with a curious kind of manic joy as he flipped again through the mysteriously re-instated entry on the planet Earth. He had a major piece of unfinished business that he would now be able to attend to, and was terribly pleased that life had suddenly furnished him with a serious goal to achieve.

It suddenly occurred to him to wonder where Arthur Dent was, and if he knew.

Arthur Dent was one thousand, four hundred and thirty-seven light years away in a Saab, and anxious.

Behind him in the backseat was a girl who had made him crack his head on the door as he climbed in. He didn't know if it was just because she was the first female of his own species that he had laid eyes on in years, or what it was, but he felt stupefied with, with... This is absurd, he told himself. Calm down, he told himself. You are not, he continued to himself in the firmest internal voice he could muster, in a fit and rational state. You have just hitch-hiked over a hundred thousand light years across the galaxy, you are very tired, a little confused and extremely vulnerable. Relax, don't panic, concentrate on breathing deeply.
