“Well, stop him if you like.”

“He’s lit off. Streaked away before we got started. Where’s his lumbago?”

“How the hell do I know! He’s shed it in your marvellous free sulphuric-acid baths,” said Dikon, but he began to feel uneasy.

“O.K., call me a fool. But you’re doing the hill. If I were you I’d keep a look-out across the reserve while you’re at it. See what Mr. Falls’s big idea is when he goes along the path. Why does he want to keep everyone off it except himself? How do we know he won’t go over the ground above the mud pot? Know what I reckon? I reckon he’s dead scared Questing dropped something when he took the toss. He’s going to look for it.”

“Pure conjecture,” Dikon muttered. “However, I’ll watch.”

Smith, like some unattractive genie, materialized out of a drift of steam. “Know what I reckon?” he began and Dikon sighed at the repetition of this persistent phrase. “I reckon it’s blind justice. After what he tried on me. I’d rather a train killed me than Taupo-tapu, by God. Give you the willies, wouldn’t it? What’s the good of looking for the poor bastard when he’s been an hour in the stock pot?”

Dikon swore at Smith with a violence that surprised himself. “It’s no good howling at me,” said Smith, “you can’t get away from the facts. C’mon, Sim.”

He moved on towards the lake.

“He reeks of alcohol,” said Dikon. “Is it wise to let him loose?”

“He’ll be O.K.,” said Simon, “I’ll keep the tags on him. You look after Falls.”

Dikon stood for a moment watching them fade into wraiths as they turned into the Springs’ enclosure. He lit a cigarette and was about to strike out for the hillcwhen he heard his name called softly.

“Dikon!”

It was Barbara in her red flannel dressing gown and felt slippers, running across the pumice in the moonlight. He went to meet her. “You called me by my first name,” he said, “so perhaps you’ve forgiven me. I’m sorry, Barbara.”

“Oh, that!” said Barbara. “I expect I behaved stupidly. You see, it hasn’t happened to me ever before.” And with an owlish imitation of somebody else’s wisdom she quoted: “It’s always the woman’s fault.”

“You little goat,” said Dikon unsteadily.

“I didn’t come out to talk about that. I wanted to ask you what’s happened.”

“Hasn’t your father—?”

“He’s talking to Mummy. I know by his voice that it’s something frightful. They won’t tell me, they never do. I must know. What are you all doing? Why are you out here? Uncle James has brought his car round and I saw Sim and Mr. Smith go out together. And when I met him on the verandah he looked so terrible. He didn’t answer when I spoke to him — just walked away to his room and slammed the door. It’s something to do with what we heard, isn’t it? Please tell me. Please do.”

“We think there may have been an accident.”

“To whom?”

“Questing. We don’t know yet. He may have just wandered off somewhere. Or sprained his ankle.”

“You don’t believe that.” Barbara’s arm in its red flannel sleeve shot out as she pointed to the hill. “You think something’s happened, out there. Don’t you? Don’t you?”

Dikon took her by the shoulders. “I’m not going to conjure up horrors,” he said, “before there are any to conjure. If you take my tip you’ll follow suit. Think what a frightful waste of the jim-jams if we find him cursing over a fat ankle, or if he merely went home to supper with the Mayor. I’m sure he adores mayors.”

“And so, who screamed?”

“Sea-gulls,” said Dikon shaking her gently. “Banshees. Maori maidens. Go home and do your stuff. Make cups of tea. Go to bed. Men must search and women must sleep and if you don’t like me kissing you don’t look at me like that.”

He turned her about and shoved her away from him. “Flaunting about in your nightgown,” he said. “Get along with you.”

He watched her go and then, with a sigh, set out for the hill.

He thought he would climb high enough to get a comprehensive view of the native thermal reserve and the land surrounding it. If anything stirred down there he should stand a good chance of seeing it in the bright moonlight. He found the track that Rua used on his evening walks and felt better for the stiff climb. Someone had suggested half-heartedly that they should at intervals call out to Questing but Dikon could not bring himself to do this. A vivid imagination stimulated by the conviction that Questing was most horridly dead made the idea of shouting his name quite appallingly stupid. However, he had promised to search so he climbed steadily until he reached a place where the reserve was spread out before him in theatrical relief. It had the curious and startling unreality of an infra-red photograph. “If it wasn’t so infernally alive,” he thought, “it would be like a lunar landscape.” He could see that the reserve was more extensive than he had imagined it to be. It was pocked all over with mud pots and steaming pools. Far out towards its eastern border he caught a glimpse of a delicate jet that spurted from its geyser and was gone. “It’s a lost world,” Dikon thought. He reflected that a man lying in one of the inky shadows would be quite invisible and decided that he had had his climb for nothing. He looked at the slopes of the hill immediately beneath him. The short tufts of grass and brush were motionless. He wandered about a little and was going to turn back when he sensed, rather than saw, that beneath him and out to his left, something had moved.

His heart and his nerves were jolted before his eyes had time to tell him that it was only Mr. Septimus Falls, moving quietly along the white-flagged path across the reserve. As far as he could make out, Mr. Falls was bent forward. Dikon remembered Simon’s theory and wondered if, after all, it was so preposterous. But Mr. Falls was still well within the bounds that he himself had set though he walked fairly rapidly towards the forbidden territory. Dikon realized with a sudden pang of interest that he was moving in a very singular manner, running when he was in the moonlight and dawdling in the shadows. The mound above Taupo-tapu was easily distinguishable; Mr. Falls had almost reached the limit of his allotted patrol. “Now,” Dikon said, “he must turn.”

At that moment a cloud passed before the face of the moon and Dikon was alone in the dark. The reserve, the path, and Mr. Falls had all been blotted out.

Clouds must have come up from the south while Dikon climbed the hill, for the sky was now filled with them, sweeping majestically to the north-east. A vague sighing told him that a night wind had arisen and presently his hair lifted from his forehead. He had brought his torch but he was unwilling to disclose himself. He had told nobody of his intention to climb high up the hill. He saw that in a minute or two the moon would reappear and he waited, peering into darkness, for the moment when Mr. Falls would be revealed.

It was not long, perhaps no more than a minute, before the return of the moonlight. After its brief eclipse the strange landscape seemed to be more sharply defined; mounds, craters, pools and mud pots, all showed clearly. He could even see the white flags along the path. But Mr. Falls had completely disappeared. iv

“Really,” Dikon thought, “if I go all jitter-bug after the problematical death of a man who was almost certainly an enemy agent, I’m not likely to be a howling success in the blitz. No doubt Mr. Falls is pottering about in the shadows. In a moment he will reappear.”

He waited and watched. He could hear his watch tick. Away to the east a night bird cried out twice. He saw a light moving about in the native village and wondered if it was Colonel Claire’s. Two or three more sprang up. They were searching about the village. Once, far below on the other side of the hill, he heard Simon and Smith call to each other. An interval in the vast procession of clouds left the face of the moon quite clear. But still Mr. Falls remained invisible.
