'Why not?'

'I'm not used to the right hand.'

'Tell me what you see,' I said. She shook her head slightly and raised the calm dark eyes.

'You will live a long time.' I glanced out through the plastic curtain. The trackers had moved off out of sight.

'How much do I owe you?' I said. She told me, and I paid her, and went quietly over to the doorway.

'Take care, dear,' she said. 'Be careful.'

I looked back. Her face was still calm, but her voice had been urgent. I didn't want to believe in the conviction that looked out of her eyes. She might have felt the disturbance of my present problem with the trackers, but no more than that. I pushed the curtain gently aside and stepped from the dim world of hovering horrors into the bright May sunlight, where they might in truth lie in wait.

There was no longer any need to ask where the balloons were. No one could miss them. They were beginning to rise like gaudy monstrous mushrooms, humped on the ground, spread all over an enormous area of grassland beyond the actual showground. I had thought vaguely that there would be two or three balloons, or at most six, but there must have been twenty.

Among a whole stream of people going the same way, I went down to the gate and through into the far field, and realised that I had absolutely underestimated the task of finding John Viking.

There was a rope, for a start, and marshals telling the crowd to stand behind it. I ducked those obstacles at least, but found myself in a forest of half inflated balloons, which billowed immensely all around and cut off any length of sight.

The first clump of people I came to were busy with a pink and purple monster into whose mouth they were blowing air by means of a large engine-driven fan. The balloon was attached by four fine nylon ropes to the basket, which lay on its side, with a young man in a red crash helmet peering anxiously into its depths.

'Excuse me,' I said to a girl on the edge of the group. 'Do you know where I can find John Viking?'

'Sorry.'

The red crash helmet raised itself to reveal a pair of very blue eyes. 'He's here somewhere,' he said politely. 'Flies a Stormcloud balloon. Now would you mind getting the hell out, we're busy.'

I walked along the edge of things, trying to keep out of their way. Balloon races, it seemed, were a serious business and no occasion for light laughter and social chat. The intent faces leant over ropes and equipment, testing, checking, worriedly frowning. No balloons looked much like stormclouds. I risked another question.

'John Viking? That bloody idiot. Yes, he's here. Flies a Stormcloud.' He turned away, busy and anxious.

'What colour is it?' I said.

'Yellow and green. Look, go away, will you?'

There were balloons advertising whisky and marmalade and towns, and even insurance companies. Balloons in brilliant primary colours and pink-and-white pastels, balloons in the sunshine rising from the green grass in glorious jumbled rainbows. On an ordinary day, a scene of delight, but to me, trying to get round them to ask fruitlessly at the next clump gathered anxiously by its basket, a frustrating silky maze.

I circled a soft billowing black and white monster and went deeper into the centre. As if at a signal, there arose in a chorus from all around a series of deep throated roars, caused by flames suddenly spurting from the large burners which were supported on frames above the baskets. The flames roared into the open mouths of the half-inflated balloons, heating and expanding the air already there and driving in more. The gleaming envelopes swelled and surged with quickening life, growing from mushrooms to toadstools, the tops rising slowly and magnificently towards the hazy blue sky.

'John Viking? Somewhere over there.' A girl swung her arm vaguely. 'But he'll be as busy as we are.'

As the balloons filled they began to heave off the ground and sway in great floating masses, bumping into each other, still billowing, still not full enough to live with the birds. Under each balloon the flames roared, scarlet and lusty, with the little clusters of helpers clinging to the baskets to prevent them escaping too soon.

With the balloons off the ground, I saw a yellow and green one quite easily; yellow and green in segments, like an orange, with a wide green band at the bottom. There was one man already in the basket, with about three people holding it down, and he, unlike everyone else in sight, wore not a crash helmet but a blue denim cap.

I ran in his direction, and even as I ran there was the sound of a starter's pistol. All around me the baskets were released, and began dragging and bumping over the ground; and a great cheer went up from the watching crowd.

I reached the bunch of people I was aiming for and put my hand on the basket.

'John Viking?'

No one listened. They were deep in a quarrel. A girl in a crash helmet, ski-ing jacket, jeans and boots stood on the ground, with the two helpers beside her looking glum and embarrassed.

'I'm not coming. You're a bloody madman.'

'Get in, get in dammit. The race has started.'

He was very tall, very thin, very agitated.

'I'm not coming.'

'You must.' He made a grab at her and held her wrist in a sinewy grip. It looked almost as if he were going to haul her wholesale into the basket, and she certainly believed it. She tugged and panted and screamed at him. 'Let go, John. Let go. I'm not coming.'

'Are you John Viking?' I said loudly. He swung his head and kept hold of the girl. 'Yes, I am, what do you want? I'm starting this race as soon as my passenger gets in.'

'I'm not going,' she screamed.

I looked around. The other baskets were mostly airborne, sweeping gently across the area a foot or two above the surface, and rising in a smooth, glorious crowd. Every basket, I saw, carried two people.

'If you want a passenger,' I said. 'I'll come.'

He let go of the girl and looked me up and down.

'How much do you weigh?' And then, impatiently, as he saw the other balloons getting a head start, 'Oh, all right, get in. Get in.'

I gripped hold of a stay, and jumped, and wriggled, and ended standing inside a rather small hamper under a very large cloud of balloon.

'Leave go,' commanded the captain of this ship, and the helpers somewhat helplessly obeyed.

The basket momentarily stayed exactly where it was. Then John Viking reached above his head and flipped a lever which operated the burners, and there at close quarters, right above our heads, was the flame and the ear-filling roar.

The girl's face was still on a level with mine. 'He's mad,' she yelled. 'And you're crazy.'

The basket moved away, bumped, and rose quite suddenly to a height of six feet. The girl ran after it and delivered a parting encouragement. 'And you haven't got a crash helmet.'

What I did have, though, was a marvellous escape route from two purposeful thugs, and a crash helmet at that moment seemed superfluous, particularly as my companion hadn't one either.

John Viking was staring about him in the remnants of fury, muttering under his breath, and operating the burner almost non-stop. His was the last balloon away. I looked down to where the applauding holiday crowd were watching the mass departure and a small boy darted suddenly from under the restraining rope, and ran into the now empty starting area, shouting and pointing. Pointing at John Viking's balloon, pointing excitedly at me.

My pal Mark, with his bright little eyes and his truthful tongue. My pal Mark, whom I'd like to have strangled.

John Viking started cursing. I switched my attention from ground to air and saw that the reason for the resounding and imaginative obscenities floating to heaven was a belt of trees lying ahead which might prevent us going in the same direction. One balloon already lay in a tangle on the take-off side, and another, scarlet and purple, seemed set on a collision course.
