which only gods get. It really means that you can't take being a god any more, which is why only gods get it you see."

"I see."

"In the final stages of it you simply lie on the ground and after a while a tree grows out of your head and then it's all over. You rejoin the earth, seep into its bowels, flow through its vital arteries, and eventually emerge as a great pure torrent of water, and as like as not get a load of chemical was te dumped into you. It's a grim business being a god nowadays, even a dead god.

"Well," she said, patting her knees. Her eyes hovered on Thor, who had opened his eyes but was only using them to stare at his own knuckles and fingertips. "Well, I hear you have an appointment tonight, Thor."

"Hmm," grunted Thor, without moving.

"I hear you've called together the Great Hall for the Challenging Hour, is that right?"

"Hmm," said Thor.

"The Challenging Hour, hmm? Well, I know that things have not been too good between you and your father for a long time. Hmm?"

Thor wasn't going to be drawn. He said nothing.

"I thought it was quite dreadful about Wales," continued Tsuliwansis. "Don't know why you stood for it. Of course I realise that he's your father and the All-Father which makes it difficult. But, Odin, Odin - I've known him for so long. You know that he made a deal once to sacrifice one of his own eyes in exchange for wisdom? Of course you do, dear, you're his son, aren't you? Well, what I've always said is he should stand up and make a fuss about that particular deal, demand his eye back. Do you know what I mean by that, Thor? And that horrible Toe Rag. There's someone to be careful of, Thor, very careful indeed. Well, I expect I shall hear all about it in the morning, won't I?"

Thor slid his back up the wall and stood up. He clasped the old woman warmly by the hands and smiled a tight smile, but said nothing. With a slight nod he gestured to Kate that they were leaving. Since leaving was what she most wanted in all the world to do she resisted the temptation to say "Oh yeah?" and kick up a fuss about being treated like this. Meekly she bade a polite farewell to the old woman and made her way out into the murky night. Thor followed her.

She folded her arms and said, "Well? Where now? What other great social events have you got in store for me this evening?"

Thor prowled around a linle, examining the ground. He pulled out his hammer, and weighed it appreciatively in his hands. He peered out into the night, and swung the hammer a couple of times, idly. He swung himself round a couple of times, again not hard. He loosed the hammer, which bounded off into the night and split open a casually situated rock a couple of dozen yards away and then bounded back. He caught it easily, tossed it up into the air and caught it easily again.

Then he turned to her and looked her in the eye for the first time.

"Would you like to see something?" he asked.

A gust of wind blew through the huge vaults of the empty station and nearly provoked in Dirk a great howl of frustration at the trail that had so suddenly gone cold on him. The cold moonlight draped itself through the long ranges of glass panels that extended the length of the St Pancras station roof.

It fell on empty rails, and illuminated them. It fell on the train departures board, it fell on the sign which explained that today was a Blue Saver Day and illuminated them both.

Framed in the archway formed by the far end of the vaulted roof were the fantastical forms of five great gasometers, the supporting superstructures of which seemed in their adumbrations to be tangled impossibly with each other, like the hoops of an illusionist's conjuring trick. The moonlight illuminated these as well, but Dirk it did not illuminate.

He had watched upwards of a hundred people or so simply vanish into thin air in a way that was completely impossible. That in itself did not give him a problem. The impossible did not bother him unduly. If it could not possibly be done, then obviously it had been done impossibly. The question was how?

He paced the area of the station which they had all vanished from, and scanned everything that could be seen
