“What do you mean by that?”

“Tell me the rest of it,” he said. “Don’t worry if it sounds odd. Believe me, you are talking to someone who has seen a lot of stuff,” he added, “that is odd. And I don’t mean biscuits.”

She nodded, and seemed to believe him. Suddenly, she gripped his arm.

“It was so simple,” she said, “so wonderfully and extraordinarily simple, when it came.”

“What was it?” said Arthur quietly.

“Arthur, you see,” she said, “that’s what I no longer know. And the loss is unbearable. If I try to think back to it it all goes flickery and jumpy, and if I try too hard, I get as far as the teacup and I just black out.”

“What?”

“Well, like your story,” she said, “the best bit happened in a café. I was sitting there, having a cup of tea. This was after days of this build-up, the feeling of becoming connected up. I think I was buzzing gently. And there was some work going on at a building site opposite the café, and I was watching it through the window, over the rim of my teacup, which I always find is the nicest way of watching other people working. And suddenly, there it was in my mind, this message from somewhere. And it was so simple. It made such sense of everything. I just sat up and thought, ‘Oh! Oh, well, that’s all right, then.’ I was so startled I almost dropped my teacup, in fact I think I did drop it. Yes,” she added thoughtfully, “I’m sure I did. How much sense am I making?”

“It was fine up to the bit about the teacup.”

She shook her head, and shook it again, as if trying to clear it, which is what she was trying to do.

“Well, that’s it,” she said, “fine up to the bit about the teacup. That was the point at which it seemed to me quite literally as if the world exploded.”

“What …?”

“I know it sounds crazy, and everybody says it was hallucinations, but if that was hallucinations then I have hallucinations in big screen 3D with 16-track Dolby stereo and should probably hire myself out to people who are bored with shark movies. It was as if the ground was literally ripped from under my feet, and … and …”

She patted the grass lightly, as if for reassurance, and then seemed to change her mind about what she was going to say.

“And I woke up in hospital. I suppose I’ve been in and out ever since. And that’s why I have an instinctive nervousness,” she said, “of sudden startling revelations that everything’s going to be all right.” She looked up at him.

Arthur had simply ceased to worry himself about the strange anomalies surrounding his return to his home world, or rather had consigned them to that part of his mind marked “Things To Think About — Urgent.” “Here is the world,” he had told himself, “here, for whatever reason, is the world, and here it stays. With me on it.” But now it seemed to go swimmy around him, as it had that night in the car when Fenchurch’s brother had told him the silly story of the CIA agent in the reservoir. The French Embassy went swimmy. The Sheraton Tower Hotel and the Bank of Abu Dhabi went swimmy. The trees went swimmy. The lake went swimmy, but this was perfectly natural and nothing to be alarmed at because a gray goose had just landed on it. The geese were having a great relaxed time and had no major answers they wished to know the questions to.

“Anyway,” said Fenchurch, suddenly and brightly and with a wide-eyed smile, “there is something wrong with part of me, and you’ve got to find out what it is. We’ll go home.”

Arthur shook his head.

“What’s the matter?” she said.

Arthur had shaken his head, not to disagree with her suggestion which he thought was a truly excellent one, one of the world’s great suggestions, but because he was just for a moment trying to free himself of the recurring impression he had that just when he was least expecting it the Universe would suddenly leap out from behind a door and go boo at him.

“I’m just trying to get this entirely clear in my mind,” said Arthur. “You say you felt as if the Earth actually … exploded.…”

“Yes. More than felt.”

“Which is what everybody else says,” he said hesitantly, “is hallucinations?”

“Yes but, Arthur, that’s ridiculous. People think that if you just say ‘hallucinations’ it explains anything you want it to explain and eventually whatever it is you can’t understand will just go away. It’s just a word, it doesn’t explain anything. It doesn’t explain why the dolphins disappeared.”

“No,” said Arthur, “no,” he added thoughtfully. “No,” he added again, even more thoughtfully. “What?” he said at last.

“Doesn’t explain the dolphins disappearing.”

“No,” said Arthur, “I see that. Which dolphins do you mean?”

“What do you mean which dolphins? I’m talking about when all the dolphins disappeared.”

She put her hand on his knee, which made him realize that the tingling going up and down his spine was not her gently stroking his back, and must instead be one of those nasty creepy feelings he so often got when people were trying to explain things to him.

“Disappeared?”

“Yes.”

“The dolphins?”

“Yes.”

“All the dolphins,” said Arthur, “disappeared?”

“Yes.”

“The dolphins? You’re saying the dolphins all disappeared? Is this,” said Arthur, trying to be absolutely clear on this point, “what you’re saying?”

“Arthur, where have you been, for heaven’s sake? The dolphins all disappeared on the same day I … “

She stared him intently in his startled eyes.

“What …?”

“No dolphins. All gone. Vanished.”

She searched his face.

“Did you really not know that?”

It was clear from his startled expression that he did not.

“Where did they go?” he asked.

“No one knows. That’s what vanished means.” She paused. “Well, there is one man who says he knows about it, but everyone says he lives in California,” she said, “and is mad. I was thinking of going to see him because it seems the only lead I’ve got on what happened to me.”

She shrugged, and then looked at him long and quietly. She laid her hand on the side of his face.

“I really would like to know where you’ve been,” she said. “I think something terrible happened to you then as well. And that’s why we recognized each other.”

She glanced around the park, which was now being gathered into the clutches of dusk.

“Well,” she said, “now you’ve got someone you can tell.”

Arthur slowly let out a long year of a sigh.

“It is,” he said, “a very long story.”

Fenchurch leaned across him and drew over her canvas bag.

“Is it anything to do with this?” she said. The thing she took out of her bag was battered and travel-worn as if it had been hurled into prehistoric rivers, baked under the sun that shines so redly on the deserts of Kakrafoon, half buried in the marbled sands that fringe the heady vapored oceans of Santraginus V, frozen on the glaciers of the moon of Jaglan Beta, sat on, kicked around spaceships, scuffed and generally abused, and since its makers had thought that these were exactly the sorts of things that might happen to it, they had thoughtfully encased it in a sturdy plastic cover and written on it, in large friendly letters, the words “Don’t Panic.”

“Where did you get this?” said Arthur, startled, taking it from her.

“Ah,” she said, “I thought it was yours. In Russell’s car that night. You dropped it. Have you been to many of these places?”

Arthur drew The Hitchhiker’s Guide to the Galaxy from its cover. It was like a small, thin, flexible lap computer. He tapped some buttons till the screen flared with text.

“A few,” he said.

“Can we go?”

“What? No,” said Arthur abruptly, then relented, but relented warily. “Do you want to?” he said, hoping for the answer no. It was an act of great generosity on his part not to say, “You don’t want to, do you?” which expects it.

“Yes,” she said. “I want to know what the message was that I lost, and where it came from. Because I don’t think,” she added, standing up and looking round the increasing gloom of the park, “that it came from here.”
