At exactly the moment that the telephone rang, the door to Kate's sitting-room opened. The Thunder God attempted to stomp in through it, but in fact he wafted. He had clearly soaked himself very thoroughly in the stuff Kate had thrown into the bath, then redressed, and torn op a nightgown of Kate's to bind his forearm with. He casually tossed a handful of softened oak shards away into the comer of the room. Kate decided for the moment to ignore both the deliberate provocations and the telephone. The former she could deal with and the latter she had a machine for dealing with.

"I've been reading about you," she challenged the Thunder God. "Where's your beard?"

He took the book, a one volume encyclopaedia, from her hands and glanced at it before tossing it aside contemptuously.

"Ha," he said, "I shaved it off. When I was in Wales." He scowled at the memory.

"What were you doing in Wales for heaven's sake?"

"Counting the stones," he said with a shrug, and went to stare out of the window.

There was a huge, moping anxiety in his bearing. It suddenly occurred to Kate with a spasm of something not entinely unlike fear, that sometimes when people got like that, it was because they had picked up their mood from the weather. With a Thunder God it presumably worked the other way round. The sky ootside certainly had a restless and disgruntled look.

Her reactions suddenly started to become very confused.

"Excuse me if this sounds like a stupid question," said Kate, "but I'm a little at sea here. I'm not used to spending the evening with someone who's got a whole day named after them. What stones were you counting in Wales?"

"All of them," said Thor in a low growl. "All of them between this size... " he held the tip of his forefinger and thumb about a quarter of an inch apart, "...and this size." He held his two hands about a yard apart, and then put them down again.

Kate stared at him blankly.

"Well... how many were thene?" she asked. It seemed only polite to ask.

He rounded on her angrily.

"Count them yourself if you want to know!" he shouted. "What's the point in my spending years and years and years counting them, so that I'm the only person who knows, and who will ever know, if I just go and tell somebody else? Well?"

He turned back to the window.

"Anyway," he said, "I've been worried about it. I think I may have lost count somewhere in Mid-Glamorgan. But I'm not," he shouted, "going to do it again!"

"Well, why on earth would you do such an extraordinary thing in the first place?"

"It was a burden placed on me by my father. A punishment. A penance." He glowered.

"Your father?" said Kate. "Do you mean Odin?"

"The All-Father," said Thor. "Father of the Gods of Asgard."

"And you're saying he's alive?"

Thor turned to look at her as if she was stupid.

"We are immortals," he said, simply.

Downstairs, Neil chose that moment to conclude his thunderous performance on the bass, and the house seemed to sing in its aftermath with an eerie silence.

"Immortals are what you wanted," said Thor in a low, quiet voice. "Immortals are what you got. It is a little hard on us. You wanted us to be for ever, so we are for ever. Then you forget about us. But still we are for ever. Now at last, many are dead, many dying," he then added in a quiet voice, "but it takes a special effort."

"I can't even begin to understand what you're talking about," said Kate, "you say that I, we - "

"You can begin to understand," said Thor, angrily, "which is why I have come to you. Do you know that most people hardly see me? Hardly notice me at all? It is not that we are hidden. We are here. We move among you. My people. Your gods. You gave birth to us. You made us be what'you would not dare to be yourselves. Yet you will not acknowledge us. If I walk along one of your streets in this... world you have made for yourselves without us, then barely an eye will once flicker in my direction."

"Is this when you're
