The big man took the scrap of paper, read the few words on it with immense slowness, then folded it with elaborate care and put it into the pocket of his coat. Again he bowed to her very slightly.

Kate suddenly realised that the check-in girl was silently waiting for her pen back to fill in the credit card form. She pushed it back at her in annoyance, handed over her own ticket and imposed on herself an icy calm.

The airport Tannoy announced the departure of their flight.

"May I see your passports, please?" said the girl unhurriedly.

Kate handed hers over, but the big man didn't have one.

"You what?" exclaimed Kate. The airline girl simply stopped moving at all and stared quietly at a random point on her desk waiting for someone else to make a move. It wasn't her problem.

The man repeated angrily that he didn't have a passport. He shouted it and banged his fist on the counter so hard that it was slightly dented by the force of the blow.

Kate picked up her ticket, her passport and her credit card and hoisted her garment bag back up on to her shoulder.

"This is when I get off," she said, and simply walked away. She felt that she had made every effort a human being could possibly be expected to make to catch her plane, but that it was not to be. She would send a message to Jean-Philippe saying that she could not be there, and it would probably sit in a slot next to his message to her saying why he could not be there either. For once they would be equally absent.

For the time being she would go and cool off. She set off in search of first a newspaper and then some coffee, and by dint of following the appropriate signs was unable to locate either. She was then unable to find a working phone from which to send a message, and decided to give up on the airport altogether. Just get out, she told herself, find a taxi, and go back home.

She threaded her way back across the check-in concourse, and had almost made it to the exit when she happened to glance back at the check-in desk that had defeated her, and was just in time to see it shoot up through the roof engulfed in a ball of orange flame.

As she lay beneath a pile of rubble, in pain, darkness, and choking dust, trying to find sensation in her limbs, she was at least relieved to be able to think that she hadn't merely been imagining that this was a bad day. So thinking, she passed out.

Chapter 2

The usual people tried to claim responsibility.

First the IRA, then the PLO and the Gas Board. Even British Nuclear Fuels rushed out a statement to the effect that the situation was completely under control, that it was a one in a million chance, that there was hardly any radioactive leakage at all, and that the site of the explosion would make a nice location for a day out with the kids and a picnic, before finally having to admit that it wasn't actually anything to do with them at all.

No cause could be found for the explosion.

It seemed to have happened spontaneously and of its own free will. Explanations were advanced, but most of these were simply phrases which restated the problem in different words, along the same principles which had given the world "metal fatigue". In fact, a very similar phrase was invented to account for the sudden transition of wood, metal, plastic and concrete into an explosive condition, which was "non-linear catastrophic structural exasperation", or to put it another way - as a junior cabinet minister did on television the following night in a phrase which was to haunt the rest of his career - the check-in desk had just got "fundamentally fed up with being where it was".

As in all such disastrous events, estimates of the casualties varied wildly. They started at forty-seven dead, eighty-nine seriously injured, went up to sixty-three dead, a hundred and thirty injured, and rose as high as one hundred and seventeen dead before the figures started to be revised downwards once more. The final figures revealed that once all the people who could be accounted for had been accounted for, in fact no one had been killed at all. A small number of people were in hospital suffering from cuts and bruises and varying degrees of traumatised shock, but that, unless anyone had any information about anybody actually being missing, was that.

This was yet another inexplicable aspect to the whole affair. The force of the explosion had been enough to reduce a large part of the front of Terminal Two to rubble, and yet everyone inside the building had somehow either fallen very luckily, or been shielded from one piece of falling masonry by another, or had the shock of the explosion absorbed by their luggage. All in all, very little luggage had survived at all. There were questions asked in Parliament about this, but not very interesting ones.

It was a couple of days before Kate Schechter became aware of any of these things, or indeed of anything at all in the outside world.

She passed the time quietly in a world of her own in which she was surrounded as far as the eye could see with old cabin trunks full of past memories in which she rummaged with great curiosity, and sometimes bewilderment. Or, at least, about a tenth of the cabin trunks were full of vivid, and often painful or uncomfortable memories of her past life; the other nine-tenths were full of penguins, which surprised her. Insofar as she recognised at all that she was dreaming, she realised that she must be exploring her own subconscious mind. She had heard it said that humans are supposed only to use about a tenth of their brains, and that no one was very clear what the other nine-tenths were for, but she had certainly never heard it suggested that they were used for storing penguins.

Gradually the trunks, the memories and the penguins began to grow indistinct, to become all white and swimmy, then to become like walls that were all white and swimmy, and finally to become walls that were merely white, or rather a yellowish, greenish kind of off-white, and to enclose her in a small room.

The room was in semi-darkness. A bedside light was on but turned down low, and the light from a street lamp found its way between the grey curtains and threw sodium patterns on the opposite wall. She became dimly aware of the shadowed shape of her own body lying under the white, turned-down sheet and the pale, neat blankets. She stared at it for a nervous while, checking that it looked right before she tried, tentatively, to move any part of it. She tried her right hand, and that seemed to be fine. A little stiff and aching, but the fingers all responded, and all seemed to be of the right length and thickness, and to bend in the right places and in the right directions.

She panicked briefly when she couldn't immediately locate her left hand, but then she found it lying across her stomach and nagging at her in some odd way. It took her a second or two of concentration to put together a number of rather disturbing feelings and realise that there was a needle bandaged into her arm. This shook her quite badly. From the needle there snaked a long thin transparent pipe that glistened yellowly in the light from the street lamp and hung in a gentle curl from a thick plastic bag suspended from a tall metal stand. An array of horrors briefly assailed her in respect of this apparatus, but she peered dimly at the bag and saw the words "Dextro-Saline". She made herself calm down again and lay quietly for a few moments before continuing her exploration.
