There was one piece of furniture that remained unchanged whilst all about raced, moved and blurred in a never-ending jumble. It was a small table with an old candlestick telephone upon it. I stepped into the room and lifted the receiver.

'Hello?'

'Hello,' said a pre-recorded voice, 'you're through to the Swindon ChronoGuard. To assist with your enquiry we have a number of choices. If you have been the victim of temporal flexation, dial one. If you wish to report a temporal anomaly, dial two. If you feel you might have been involved in a time crime . . .'

It gave me several more choices, but nothing that told me how to contact my father. Finally, at the end of the long list, it gave me the option for meeting an operative, so I dialled that. In an instant the blurred movement in the room stopped and everything fell into place — but with furniture and fittings more suited to the sixties. There was an agent sitting at the desk, a tall and undeniably handsome man in the blue uniform of the ChronoGuard, emblazoned at the shoulder with the pips of a captain. As he himself had predicted, it was my father, three hours later and three hours younger. At first, he didn't recognise me.

'Hello,' he said, 'can I help you?'

'It's me, Thursday.'

'Thursday?' he echoed, eyes wide open as he stood up. 'My daughter Thursday?'

I nodded and he moved closer.

'My goodness!' he exclaimed, scrutinising me with great interest. 'How wonderful to see you again! How long's it been? Six centuries?'

'Two years,' I told him, not wanting to confuse a confusing matter even further by mentioning our conversation this morning, 'but why are you working for the ChronoGuard again? I thought you went rogue?'

'Ah!' he said, beckoning me closer and lowering his voice. 'There was a change of administration and they said they would look very closely at my grievances if I'd come and work for them at the Historical Preservation Corps. I had to take demotion and I won't be reactualised until the paperwork is done, but it's working out quite well otherwise. Is your husband still eradicated?'

'I'm afraid so. Any chance . . . ?'

He winced.

'I'd love to, Sweetpea, but I've really got to watch my Ps and Qs for a few decades. Do you like the office?'

I looked at the sixties decor in the tiny room.

'Bit small, isn't it?'

My father, who was clearly in an ebullient mood, grinned. 'Oh yes, and over seven hundred of us work here. Since we could not all be here at one time, we simply stretch the usage out across the timestream like a long piece of elastic.'

He stretched his arms wide as if to demonstrate.

'We call it a timeshare.'

He rubbed his chin and looked around.

'What's the time out there?'

'It's 14 July 1988.'

'That's a stroke of good fortune,' he said, lowering his voice still further. 'It's a good job you've turned up. They've blamed me for the 1864 war between Germany and Denmark.'

'Was it your fault?'

'No — it was that clot Bismarck. But it doesn't matter. They've transferred me to another division inside the Historical Preservation Corps for a second chance. My first assignment occurs in July 1988, so local knowledge right now is a godsend. Have you heard of anyone named Yorrick Kaine?'

'He's Chancellor of England.'

'That figures. Did St Zvlkx return tomorrow?'

'He might.'

'Okay. Who won the Superhoop?'

'That's Saturday week,' I explained. 'It hasn't happened yet.'

'Not strictly true, Sweetpea. Everything that we do actually happened a long, long time ago — even this conversation. The future is already there. The pioneers that ploughed the first furrows of history into virgin timeline died aeons ago — all we do now is try and keep it pretty much the way it should be. Have you heard of someone named Winston Churchill, by the way?'

I thought for a moment.

'He was an English statesman who seriously blotted his copybook in the Great War, then was run over by a cab and killed in 1932.'

'So, no one of any consequence?'

'Not really. Why?'

'Ah, no reason. Just a little pet theory of mine. Anyway, everything has already happened — if it hadn't, there'd be no need for people like me. But things go wrong. In the normal course of events, time flies back and forth from the end of then until the beginning of now like a shuttle on a loom, weaving the threads of history together. If it encounters an obstacle then it might just flex slightly and no change will be noticed. But if that obstacle is big enough — and Kaine is plenty big enough, believe me — then history will veer off at a tangent. And that's when we have to sort it out. I've been transferred to the Armageddon Avoidance Division, and we've got an apocalyptic disaster of life-extinguishing capability, Level III, heading your way.'

There was a moment's silence.

'Does your mother know you wear your hair this short?'

'Is it meant to happen?'

'Your hair?'

'No, the Armageddon.'

'Not at all. This one has an Ultimate Likelihood Index rating of only twenty-two per cent: "not very likely".'

'Nothing like that incident with the Dream Topping, then,' I observed.

'What incident?'

'Nothing.'

'Right. Well, since I'm on probation — sort of — they thought they'd start me on the small stuff.'

'I still don't understand.'

'It's simple,' began my father. 'Two days after the Superhoop President Formby will die of natural causes. The following day Yorrick Kaine proclaims himself dictator of England. Two weeks after that, following the traditional suspension of the press and summary executions of former associates, Kaine will declare war on Wales. Two days after a prolonged tank battle on the Welsh Marches, the United Clans of Scotland launch an attack upon Berwick-upon-Tweed. In a fit of pique Kaine carpet-bombs Glasgow and the Swedish empire enter on Scotland's side. Russia joins Kaine after their colonial outpost of Fetlar is sacked — and the 'war moves to mainland Europe. It soon escalates into an apocalyptic shoot-out between the African and American superpowers. In less than three months the earth will be nothing but a steaming radioactive cinder. Of course,' he added, 'that is a worst-case scenano. It'll probably never happen, and if you and I do our jobs properly, it won't.'

'Can't you just kill Kaine?'

'Not that easy. Time is the glue of the cosmos, Sweetpea, and it has to be eased apart — you'd be surprised how strongly the historical timeline tends to look after despots. Why do you think dictators like Pol Pot, Bokassa and Idi Amin live such long lives and people like Mozart, Jim Henson and Mother Teresa are plucked from us when relatively young?'

'I don't think Mother Teresa could be thought of as young.'

'On the contrary — she was meant to live to a hundred and twenty-eight.'

There was a pause.

'Okay, Dad — so what's the plan?'

'Right. It's incredibly complex and also unbelievably simple. To stop Kaine gaining power we have to seriously disrupt his sponsor, the Goliath Corporation. Without them, his power is zero. To do that we need to ensure . . . that Swindon wins the Superhoop.'

'How is that going to work?'

'It's a causality thing. Small events have large consequences. You'll see.'

'No, I mean, how am I going to get Swindon to win? Apart from Kapok and Aubrey Jambe and perhaps "Biffo" Mandible, the players are, well, crap — not to put too fine a point on it. Especially when you compare them to their Superhoop opponents, the Reading Whackers.'

'I'm sure you'll think of something, but keep an eye on Kapok — they'll try to get to him first. You'll have to do this on your own, Sweetpea, I've got my own problems. It seems Nelson getting killed at the beginning of the battle of Trafalgar wasn't French History Revisionists after all. I talked to someone I know over at the ChronoGendarmerie and they thought it amusing that the Revisionists should even attempt such a thing; advanced timestream models with Napoleon emperor of all Europe bode very poorly for France — they're much better in the long run with things as they are meant to be.'
