'In a dream I walked the length of the valley of flowers. It rained on me again, the storm coming out of nowhere. Eventually the scenery began to make sense and I found the stream where I had left Panda and George. But I did not find them, not until I reached Gangotri a couple of days later. They were much relieved to see I was all right. They said they had searched for me, and when they didn't find me, they thought our paths had crossed and that I had returned to Gangotri ahead of them. They wanted to know where I had been all this time, but for some reason I didn't tell them. I just said I had gotten lost. I did try to find the old sannyasi who had told me about Devashan, however. I thought I might tell him of my adventure. But he must have left town. Sannyasis are always wandering from one place to another.

  'Panda and George had to return to their family and I let

  them go. Despite what the yogi had said about my not seeing him again, I wanted to go back. I pored over maps in Gangotri. A lot of good it did me. I couldn't find any of the peaks I had seen near the yogi's cave. Still, I returned to Devashan and hiked up and down the valley three times looking for signs of the place. I looked and looked. If it had not been for the ring in my pocket, I might have believed I had imagined the whole episode. I guess it goes without saying that I didn't find the cave. What was I to do? My vacation was almost up. I was going to Mars soon. I returned to the States, excited about what I had discovered, but also frustrated that its mystery had been left unsolved.

  'Back in Houston I performed a number of tests on the ring. I tried to scratch it with a diamond and failed. I subjected it to an electron scan and found it to be a perfect circle, and I mean perfect. I dipped the ring in concentrated acids and got no reaction. By this time I knew it wasn't silver or gold. Finally I put it under the laser they have at the University. I was scared to do it, but I also had a peculiar faith in the magic of the ring. I set the laser at full power and pushed the button. It didn't do a thing to it. Let me impress upon you how extraordinary a fact that is. Nothing known to man could have withstood such a concentration of energy.

  'I've already commented on the ring's shine. That shine never fades. I've never had to polish it. Occasionally the ring even appears to shine in the dark. But that may be merely my imagination.'

  Jim paused once more. The sun was setting. The canyon beneath them was falling into long shadows. It was difficult for Jim to watch the sun going down and convince himself that it was the same sun that set on Earth.

  'Well, that's my story,' he said finally. 'I've talked for a

  while. You've been good listeners. I suppose now you must have questions. I assure you, I won't be offended if you don't believe a thing I've said. Sometimes I wonder myself if it wasn't just a dream. But then, you've seen the ring too, Lauren.'

  'Why did you give the ring to Jenny?' Lauren asked.

  'I did it on the spur of the moment,' Jim said. 'I've always adored your sister. I thought she would like to have it.'

  'How many people have you told about this?' Gary asked.

  'Only you two.'

  'Are you sure the laser was on high power?' Gary asked.

  'Yes. Full power. It didn't even heat the ring.'

  'That's impossible,' Gary said. 'What could it have been made of?'

  Jim shook his head. 'Nothing known to man.'

  'What did you do with the canteen of water?' Gary asked.

  'I took it home to the States in a sealed bottle. It's in a box at my apartment in Houston. I never drank any of it.'

  Lauren peered at him closely. 'Why did you tell us this story?' she asked. 'Why did you tell us now?'

  'To prepare you,' Jim said.

  'For what?' Lauren asked.

  Jim hesitated, unsure of how to explain himself. The reasons were unclear in his own mind. He wanted to give Lauren and Gary a sense for the supernormal, and open their minds to things they never considered. He knew they respected him; they seemed to believe his story, and had certainly been moved by it. But he knew he had to be careful about speaking directly. Gary was easily suggestible. Jim had watched him reading his books. Gary would be genuinely scared at the tense parts, would laugh at the humorous spots, and would grow angry at the villains. He

  was remarkably innocent given his heavy responsibilities. He was also impulsive, and extremely protective of Lauren. Jim knew Gary would blow Bill's head off if he told him everything he was thinking.

  Lauren was different. She was the most intuitive woman Jim had ever met, sensitive to feelings in others few would have noticed. Her intelligence and resourcefulness were obvious to everyone. Yet she had a hard-headed side that categorized everything as either black or white. To say what he wanted, he needed to move through a sea of gray. He didn't know how she would react.

  'Did you know that we've lost contact with the Nova?' Jim asked.

  'Shit,' Gary said. 'Is it the generators?'

  'I don't think so,' Jim said.

  'What then?' Lauren asked.

  'I'm not positive,' Jim said, 'but I have theories. That is why I told you my story, to make my theories more acceptable to you two. Where should I begin? You asked about this hole where the Russian ship is supposed to be. What do you think caused it, Gary?'

  'There must have been an explosion of some kind. But then there should be signs of wreckage, even with the snow here. It confuses me. Even if all their fuel exploded at once, it couldn't have made this size hole. But I know that ship landed here. I'm sure of it.'

  'Do you have any theories, Lauren?' Jim said.

  'No.'

  'I'll tell you what happened,' Jim said. 'Coming to Mars, we knew there was always a chance we might catch an alien disease. Especially in light of how the Russians disappeared. Now an infection, as Lauren well knows, can be subtle. You can have a disease and not know it. In fact, you can have a disease that produces obvious symptoms and still not know that you're sick. The disease could be such that it makes you incapable of thinking you're ill. Am I right, Lauren?'

  Her tone was cautious. 'In rare cases, yes.'

  'The possibility existed when we set out for Mars that we could catch such a disease. How great the chances were, no one could say for sure. But look at what was at stake - the lives of five billion people. Every precaution had to be taken that we didn't return to Earth with an infection. In the Soviet Union they followed similar reasoning. The Russian ships were equipped with devices that could completely destroy any infection.'

  'What devices?' Lauren asked.

  'The Karamazov, the orbiting Gorbachev, and the lander we have been unable to locate, all carry or carried thermonuclear war heads.'

  'Jesus!' Gary exclaimed. 'That's what made this hole. Wait a second. How do you know that the Russian ships have bombs aboard?'

  'I assume that they do,' Jim said. 'I'm certain I'm right. It explains this hole. And, you see, we have a similar warhead aboard the Hawk.'

  'What?' Gary cried.

  'Tell me you're kidding,' Lauren said.

  'We have a warhead,' Jim said. 'Bill and I have known about it since before we left. If at any time we feel we have caught an unusual infection, we are to contact Houston. They will study the disease, as we will study it here. But even if our symptoms disappear, we are never to return home. We could be carriers. The danger would be too great.'

  'We're just supposed to blow ourselves up?' Lauren asked.

  'Yes,' Jim said.

  'Why wouldn't they just let us die here?' Lauren asked. 'Why the bomb?'

  'The bomb is there in the event that some of us want to return and some don't,' Jim said.

  'Where is it?' Gary asked.

  'In the basement - in the garage. It's well shielded. I don't know exactly how powerful it is.'

  'Are you saying the Russians used their bomb,' Lauren asked 'and killed themselves intentionally?'

  'Yes,' Jim said. 'More specifically, I think Commander Dmitri Maximov detonated it. Only the top two ranks of our crew knew about the Hawk's bomb. I imagine the Russians would
have followed a similar procedure. Ivan was second in command. We know he didn't trigger it.'

  'Why didn't NASA tell me?' Lauren asked. 'I'm the doctor.'

  'You're also the youngest,' Jim said. 'It's very difficult to push a button that you know will kill you.'

  'I see,' Lauren said. 'So you feel Dmitri was convinced his crew was contaminated, and that he tried to stop the infection before it could spread to Earth?'

  'Yes,' Jim said.

  Gary sighed. He said it for all of them. 'That means we probably have the same disease. And that we can never go home.' There was a silence. The sun had set. Their own personal night was about to begin, Jim thought. It would be long. He spoke gently. 'Not necessarily. Perhaps this infection is localized, and spreads only through a specific mechanism.'

  'There is something wrong with this whole theory,' Lauren said. 'How could Carl have caught the disease?'

  'Yeah,' Gary said. 'And if Ivan was infected with this disease, and didn't give a damn about the Earth, why didn't he try to return in the KaramazovT

  'I will answer your question first, Gary,' Jim said. 'I think Dmitri sabotaged the Karamazov. That way he could lure all his crew to the other lander and blow them up. But Ivan must have been wary, and not fallen for the trap. That is my belief.'

  'But what about Carl?' Lauren insisted. 'He never came down here. He couldn't have caught anything.'

  'Are you sure?' Jim asked softly. The time had come to spill his heart.

  'There is no germ that can cross two hundred miles of empty space,' Lauren said.

  Jim sighed. He knew it would all sound so crazy. He had to ask himself if he hadn't already caught something. 'The disease that infects this planet isn't physical,' he said.

  'Huh?'Gary said.

  'What do you mean?' Lauren asked anxiously.

  'Hear me patiently, and with an open mind. Tourists in Western Europe often comment on the difference in the air when they cross from one country to the next, even just at the border. You walk a few feet, and even if your eyes are closed, you still know you're in a different country. People who travel report this all the time. But why? Is the reason psychological? That's a catch-all phrase that says nothing. I believe it's a perception of non-physical influences. These influences must exist. We don't have to - we shouldn't -delve into psychic phenomena to find them. They represent the most intimate aspects of our lives. We have hopes and dreams and thoughts. None of these could be located or explained by a physicist. There is an entire universe of forces we cannot perceive with our senses, or with any instrument man can build. Nevertheless, these forces exist, along with their effects. I have spent decades prowling through old ruins, and digging up the past. Often, sitting alone in those places late at night, I came to know the

  people who once lived there; what they were like, whether they were a proud people, a happy people, or a miserable and vicious people. Life is a mysterious thing. It has a quality that doesn't necessarily die when a people dies. Two miles beneath the Himalayas, I felt life. I felt goodness. Here there is another kind of power, a power that goes on and on, that never stops.'

  'What the fuck are you talking about?' Lauren asked.

  'A power,' Jim repeated, mostly to himself. 'Death. This planet is dead. But it does not rest easily. It is envious of us. It's trying to infect us.' He stopped himself. He hadn't meant to get so esoteric.

  'Are you talking about Ivan?' Gary asked, confused.

  Jim shook his head. 'I doubt if he can be put back together. But he could never have lived here for two years. We all know that. Why don't we face it?'

  'Face what?' Lauren asked, sounding annoyed.

  'Oh shit,' Gary said, burying his face in his hands. 'My nightmares are bad enough as they are.'

  Jim nodded. 'We've all been having nightmares. We don't talk about them, though, and they never really scare us, not enough to drive us away. Quite the opposite. They add to the fascination of this planet. Many things do. Impressions in the sand that begin to look like footprints -if you look long enough. Canals that flow only underground, but canals that can still be seen from millions of miles away in a telescope if you look long enough. A cosmonaut who closes every window in his ship and then gouges out his eyes so that he won't have to look at Mars, so he won't have to see what Mars is doing to him. And what was Mars doing to him? It must have been something incredible, because when this same cosmonaut cut his throat, his blood didn't freeze, not even after floating around in a gigantic icebox for two years. Then there is the

  other cosmonaut who lives quite comfortably in an icebox for two years. But none of this makes you run away. You want to stay and investigate the mysteries. You're curious, of course, and you're also afraid if you don't figure things out, then the danger will remain, and wait for another day, another time.'

  'Why don't we get out of here, Jim?' Gary asked suddenly, scared.

  'None of this makes any sense,' Lauren protested. 'You can't get infected by something that doesn't physically exist. How could you?'

  'I don't know,' Jim said. 'Yet.'

  'I'm not curious,' Gary said. 'Let someone else find out what's happening. Let's just get the fuck out of here.'

  'We can't,' Jim said.

  'Why not?' Gary demanded. 'I can have us ready to blast off in half an hour.'

  Jim took a breath. 'Because of Bill.'

  'Talk to him,' Gary said. 'Tell him we're in danger of catching whatever the hell you're talking about. He respects you. He'll listen.'

  'No,' Lauren said softly, deadly. 'That's not what you meant, is it, Jim? You're saying Bill's like Ivan.'

  'No,' Jim said quickly.

  'Yes, you are!' Lauren snapped. 'You've just been leading up to the fact that you think he has to be killed. Well, it's all bullshit. If anyone's been infected, it's you.'

  'Lauren,' Jim said softly, 'he was down there too long. His air should have run out. At best, I was hoping to find his body.'

  'You're not sure!' Lauren cried. 'He could have had extra tanks.'

  Gary shook his head at the ground. 'Oh, shit. Oh, shit.'

  'I checked his supplies before he left,' Jim said. 'I know

  exactly how much air he brought with him. It was a lot, but not enough to be down there as long as he was.'

  'I don't believe you!' Lauren yelled.

  "Then why are you so upset?' Jim asked.

  Lauren was on the verge of tears. 'Because I love you, Jim. I trust you. I don't want you saying things.' She bowed her head and clenched her gloved hands. 'I can't rest here. When I sleep, I feel like I can't breathe, like I'm smothering. I have these nightmares of something horrible climbing on top of me.' She coughed. 'He was trying to drag me into that water. He was so strong. No one that skinny could be so strong. And he just came out of the water. He was waiting in the water.' She closed her eyes and her cheek twitched. 'I keep asking myself how he could have been in that water. His suit wouldn't have worked. It's impossible. You know, I didn't want to cut him in half, but he wouldn't let go of me. Then, when I shot him, he was still grinning at me. He was dead and he was still grinning at me.'

  Gary put his arm around Lauren. 'No one's going to get you again like that, Doc,' he said. He looked at Jim. 'You really think Bill's like Ivan? If he is, he's dead, and I'm sorry. We're not taking any fucking zombie back home with us.'

  'No,' Jim said. 'Lauren's right. We're not sure about anything. My whole theory could be insane. How do I know I'm not sick? I'm sure Bill thinks he's perfectly well. And he's different from Ivan. I asked him about Jessie, and by the way he responded I could tell he still loves her. I doubt if the Ivan we met loved anybody.' Jim stood and looked in the direction of Olympus Mons. 'We need more facts. Tomorrow Bill wants to show me the big secret under the ground. I'll go with him. But I think I'll insist that Jessie come along. There could be safety in her company. As a further safeguard, we'll say the laser we brought with us

  accidentally fell into the canyon and was lost. We'll hide it near th
e Karamazov in case either of you need it. I'm also going to give you both the code to the warhead. It can be triggered through Friend. But I believe Bill has manipulated the computer's programs. I think that's why our communications are out. I fear they're gone for good. But the bomb can be detonated manually. I'll explain the details on the way back. I pray it doesn't come to that. But you know one thing above all else: Earth must be protected.'

  They walked back to Hummingbird in silence. But climbing into the hovercraft, Lauren spoke up. 'Your cavern in India reminds me of the one Bill's found.'

  'They are much alike,' Jim agreed.

  She suddenly gripped his arm. 'I know why you told us that story,' she said. 'You think there's a reason why you discovered that ring.'

  Jim smiled. 'Your sister always reminded me of Cinderella. Maybe the yogi wanted Jenny to finally receive her glass slipper.'

  Lauren was not smiling. 'Say it to me straight. What do you think's going on here?'

  Jim thought for a moment. 'I said this infection is alien, but it reminds me of legends on Earth, of ghost stories.' He paused. 'I think this planet's haunted.'

  TWENTY-THREE

  The press room was crowded. Along with twenty other reporters, Terry Hayes waited for Dean Ramsey to make a statement on the fate of Project Nova. The public had heard nothing from Mars for two days, not since Colonel William Brent, Professor James Ranoth, and Dr Lauren Wagner had gone to inspect the Karamazov.

  'Here comes the asshole now,' Tom Brenner, Terry's partner, said in his ear. Flanked by two Air Force officers, Ramsey emerged from a pair of swinging doors at the side of the stage. Everybody stood. They were tense; the whole country was nervous. The word on the streets said that Mars had Martians after all, and that they weren't friendly. Terry wasn't sleeping well. Ramsey didn't look as if he was, either.
