Kim studiously avoided bringing the subject up again. That evening they wandered down to the rec room and watched, but did not participate in, Party of Five, a light comedy in which the lead characters discover they are living next door to a group marriage with two husbands and three wives.

Party of Five did not get many laughs, and Kim spent most of her time thinking how cavernous the ship felt. Solly tried to look relaxed, but he kept laughing at the wrong parts.

Before they went to bed, he reactivated the AI, but did not return control of the systems to it. “Ham, have you been making progress with the virus?”

The windows opened out onto an ocean. In the distance, Kim could see a whale spouting.

“Ham?” said Solly. “Answer up.”

He glanced sidewise at her and tried again. The AI had always responded within seconds.

Kim got up, put her hands in her pockets, and turned away from the seascape. “It sounds as if it’s down altogether,” she said.

“Apparently.”

“Ever know it to happen before?”

“Never. But this is also the first time I’ve had to shut down an AI. Maybe it has that kind of effect.”

“Ham,” she said. “Are you there?”

They went up to the pilot’s room and Solly sat down at the console and initiated a diagnostic. “This’ll take a few minutes,” he said.

The windows opened onto the same seascape, although the whale was gone.

“When we get back,” she said suddenly, “you aren’t going to walk away from me, are you?”

“No.” Solly put an arm around her. “I love you, Kim.”

He gathered her in and they kissed.

“Kim—” he said.

“Yes—?”

“Will you marry me?”

It came without warning. “Yeah,” she said, carefully keeping her voice level. “I think I’d like to do that.”

The diagnostic chimed. It showed no problem. Everything was fine.

“That can’t be,” said Solly. “I mean, we can’t even raise the AI.”

Solly broke out the captain’s best stock that evening to celebrate their engagement. They made love to candlelight and soft music, starting in the briefing room, where the windows were full-length and provided a glorious view from the top of Mount Morghani, pausing once on the third-floor landing, and continuing with unabated zeal into the bedroom.

Even though they were alone on the ship, Kim always took care to close the bedroom door. On this occasion, however, Solly carried her in and tumbled her among the sheets, and so the door remained open.

The night went on and on, with occasional downtime for him during which they talked of the future. And then Solly came for her again, and she delightedly gave herself to him.

He was inexhaustible that night. Even with a body that was effectively twenty years old, he seemed to be performing above and beyond the call. But she stayed with him and there came a moment when he was lying with his head toward the foot of the bed and he brought her down atop him, turning her on her back, spread-eagling her.

She luxuriated in the sensation of his body beneath hers, his lips against the nape of her neck, his hands exploring her. The illumination in the ship had dimmed to nighttime levels, which meant the passageway behind her was dark save for the soft glow of the security lights.

Her head was thrown back in ecstasy and she was groaning and sighing, partly because she was inclined to do so, partly because she knew it inflamed him. Her line of vision went through the open door into the corridor.

And she saw something move.

It was a glimmer, a shadow, something at the far edge of awareness. Yet it was there.

She was immediately trying to get Solly to stop. But he was at full throttle.

Something was taking shape back there.

A pair of eyes. From the darkness near the top of the doorway, just outside in the corridor.

Suddenly she was back in Kane’s villa, terrified in the cool emotionless gaze of the thing in that other passageway. Solly’s hands were still holding her, playing with her. She pulled them away and rolled off onto the floor and, without taking her eyes from the apparition, got Solly to understand something was wrong and began feeling around for a weapon. The best she could find was a shoe.

“What’s the matter?” he asked, startled.

The eyes were the same emerald color, but flecked with gold. Vertical irises. Cat’s eyes. Cool, dispassionate, surgical. Very much like the thing in Kane’s villa. But she saw no madness here. Only malevolence.

The eyes were disembodied.

They floated a few centimeters from the ceiling.

Solly was staring down at her but she held a hand against his back, trying to get him to stay still. She found the remote, which was on a side table, and touched it. The lights came on.

Solly looked at her. Looked out into the passageway.

It was empty.

“Kim?” Solly looked down at her. “What’s wrong?”

She was weak, unable to move. “It was outside the room.”

“Outside? What was outside?” He padded into the corridor and looked both ways. “Nothing here,” he said. “What did you think you saw?”

She tried to describe it but it just came out sounding hallucinatory.

“All right,” he said, when she’d compared it to the thing in the lake. “Let’s find out.”

She got into her clothes and Solly pulled on a pair of shorts and detached a lampstand to use as a weapon. Then they examined each room on the third floor, Solly doing the actual search while Kim stayed in the corridor to ensure that nothing got behind them.

He looked in closets and cabinets and behind beds. They moved with deliberation, and Kim was pleased to see that, despite the absurdity of her claim, he took her seriously rather than simply trying to argue what he must have thought: that she’d been seeing things.

They went down to the second floor and repeated the process, and then finally they searched the bottom of the ship. Long windows allowed them to see into all of the storage areas and the launch bay. He even climbed down into the lander through the open cockpit. The lander itself was attached to the Hammersmith’s underside. They inspected the areas given over to the recycling systems, water tanks, and cargo. They looked in the engine room. When they were finished he turned to her. “Kim, there’s no place left to hide.”

It didn’t matter. “I saw it,” she said. It was impossible, and she wanted to put it aside, wanted desperately to believe it was an illusion. A dream. A result of the wine she’d drunk earlier in the evening. But she’d been wide awake. Solly had seen to that.

“It was there,” she said. “It vanished when I put on the lights.”

“Like a reflection would have done.”

“Yes.”

“But it wasn’t a reflection.”

“No. It wasn’t. Couldn’t have been.”

There was egress to interior wiring and systems compartments through several access panels. But it would have required time to remove and then replace them. He looked at them, and they were locked down tight.

“I saw it.”

“I believe you.”

They went back up to their room, walking softly along the carpeted floors, and turned out the lights, returning the ship’s illumination to what it had been. Kim looked into the semidarkness, studied the row of tiny security lamps which came on automatically when the ship dimmed down for nighttime running. There was nothing that could have fooled her into thinking she’d seen a pair of eyes.

The most frightening aspect was the thing’s resemblance to the earlier apparition. She wondered if it had somehow contrived to follow her out here.

She’d brushed aside the experience in the Severin Valley, locked it in a remote corner of her mind, and convinced herself it had been a trick of the light, or a product of an over-supply of oxygen.

Now she was confronted by it again. And for the first time in her adult life, she questioned her worldview, her assumption that the universe was rational. That it was governed by self-consistent laws. That there was no place for the supernatural.
