‘They had a wizard in to look at it,’ said Groat. ‘He said the machine twists just a little bit of the universe so pie
‘Why didn’t you switch it off?’
‘Couldn’t, sir. It kept on going like a siphon. Anyway, the wizard said if we did that terrible things might happen! ‘cos of, er, quantum, I think.’
‘Well, then, you could just stop feeding it mail, couldn’t you?’
‘Ah, well, sir, there it is,’ said Groat, scratching his beard. ‘You have positioned your digit right on the nub or crux, sir. We should’ve done that, sir, we should’ve, but we tried to make it work for us, you see. Oh, the management had schemes, sir. How about delivering a letter in Dolly Sisters thirty seconds after it had been posted in the city centre, eh? Of course, it wouldn’t be polite to deliver mail before we’d actually got it, sir, but it could be a close run thing, eh? We were good, so we tried to be better… ’
And, somehow, it was all familiar…
Moist listened glumly. Time travel was only a kind of magic, after all. That’s why it always went wrong.
That’s why there were postmen, with real feet. That’s why the clacks was a string of expensive towers. Come to that, it was why farmers grew crops and fishermen trawled nets. Oh, you
That’s why it was left to wizards, who knew how to handle it safely. Not doing any magic at all was the chief task of wizards - not ‘not doing magic’ because they couldn’t do magic, but not doing magic when they could do and didn’t. Any ignorant fool can fail to turn someone else into a frog. You have to be clever to refrain from doing it when you know how easy it is. There were places in the world commemorating those times when wizards hadn’t been quite as clever as that, and on many of them the grass would never grow again.
Anyway, there was a sense of inevitability about the whole business. People wanted to be fooled. They really believed that you found gold nuggets lying on the ground, that this time you could find the Lady, that just for once the glass ring might be real diamond.
Words spilled out of Mr Groat like stashed mail from a crack in the wall. Sometimes the machine had produced a thousand copies of the same letter, or filled the room with letters from next Tuesday, next month, next year. Sometimes they were letters that hadn’t been written, or might have been written, or were meant to have been written, or letters which people had once sworn that they had written and hadn’t really, but which nevertheless had a shadowy existence in some strange invisible letter world and were made real by the machine.
If, somewhere, any possible world can exist, then somewhere there is any letter that could possibly be written. Somewhere, all those cheques really are in the post.
They poured out - letters from the present day which turned out not to be from
The wizards from Unseen University had been jolly interested in the problem, like doctors being really fascinated by some new virulent disease; the patient appreciates all the interest, but would very much prefer it if they either came up with a cure or stopped prodding.
The machine couldn’t be stopped and certainly shouldn’t be destroyed, the wizards said. Destroying the machine might well cause this universe to stop existing, instantly.
On the other hand, the Post Office
The letters ceased, at least. This came as a huge relief, but nevertheless the Post Office had its regulations and so the Chief Postal Inspector was brought before Postmaster Cowerby and asked why he had decided to risk destroying the whole universe in one go.
