About Lake of Darkness, by Adam Roberts
An expedition to explore a black hole discovers, or seems to, that some being or beings are living inside the event horizon. A crewmember, Raine, claims he has been contacted by a being he calls "The Gentleman," goes murderously mad, and kills all his crewmates. Evil passes like a contagion through the utopian societies of the far future. A second expedition is mounted and returns to the black hole. Its lead scientist, Guunarsonsdottir, is convinced an alien species has evolved inside the exacting conditions of the black hole, and that communications can be opened across the event horizon. Joyns, a mission specialist, comes to fear that something malevolent, an ancient evil, is inside the black hole, wanting to escape. The mood aboard the ship deteriorates, and the crew split into two factions, fighting amongst themselves. Joyns is confined to quarters.

From Lake of Darkness
But she couldn’t sleep. She turned from her left to her right side and then again to her left, feeling the slight difference when she turned with the direction of spin as opposed to against it. She instructed the room to turn out all lights but then felt abandoned and scared in the dark, and so ordered the lights back on, to shine a low yellow-orange glow. She lay on her back. She tried to compose her mind into a meditative state, but it wouldn’t settle. She got up and knelt and prayed, but it was a vacancy, a mere going through the motions, and she soon stopped.
It was impossible to sleep.
At one point she heard two people outside her room. Given the great size of the startship and the relatively small number of crew, this was odd. Joyns sat up, believing they had specifically come to speak with her, and wondering why they hadn’t simply called her. But they hadn’t come to her.
There were two of them, one who sounded a little like Samuel, the other whose voice she didn’t recognise. That struck Joyns as odd, because she thought Guunarsonsdottir had barricaded herself and her followers in a separate part of the ship. But there they were, outside her room. Or their voices at any rate. Perhaps the barricade had been breached and Guunarsonsdottir’s followers were on the run. Perhaps they themselves were staging a raid behind enemy lines. The two of them were talking loudly about the best way of incapacitating Saccade—which must mean not only that Saccade had arrived, but the news of her advent must have reached Guunarsonsdottir’s portion of the ship as well. One of the two, perhaps Samuel said, distinctly, "kill her, it’s the only way" and the other person, Joyns didn’t recognise their voice, said: "she’s really here! really! she’s here!" and then laughed like a cat miaowing, then their voices dropped and Joyns couldn’t follow them. There followed a strange melange of sounds, scrapings and gruntings and smacking sounds, and it took Joyns a moment to piece together than the two figures were grappling and fighting one another.
Then there was a loud slapping sound, and the sound of somebody running away, their footsteps slightly syncopated by the fact that one foot was placed more spinwise than the other.
Had both parties run away? Was one lying wounded or dead outside her door?
Joyns contemplated getting up and checking, but a deep resistance to the idea occupied her limbs. She sat up and checked the ship’s time. One minute to midnight—the startship’s arbitrary midnight, by which the arbitrary business of timekeeping was calibrated, as it was on a million ships and habitats around the inhabited galaxy. I should get up, she told herself. But she did not.
It was dead midnight and the lights in her room glowed blue.
She hadn’t told the room to change the colour, and it was a chilly, morbid shade of blue that was accompanied by a distinct drop in temperature. She hadn’t ordered that either! It certainly wasn’t going to help her get to sleep, so she said "Room!" preparatory to ordering it to restore the earlier light and heat settings when she saw she was not alone.
She saw at once who it was: the Gentleman. He was dressed in a mauve jacket and trousers, the jacket sharply cut and folded over a harlequin-green shirt and necktie, after the manner and style of an actor in an historical drama. He carried a walking stick shaped like the Hebrew letter vav. His face was lean and sharp-featured. Joyns was not a fan of antique painted art and so was unaware of the old Vannick painting The Arnolfini Betrothal, but had she ever seen that image she would have recognised the face of the man in her visitor (though not the lavish Flemish cloak; the Gentleman wore nothing so voluminous). And here he was, as—Joyns assumed—he had appeared to Raine, years before. He was seated in a chair that had not been there before, surveying Joyns with prominently-lidded eyes.
"Good grief," said Joyns.
"Half right," said the Gentleman.
"You’re not here," Joyns said. She drew herself back along the floor, and rested her spine against the wall of her room. If she sprinted she would surely reach the door before the Gentleman could stop her. Indeed, it looked, from his demeanour and his posture, as if any decision on his part to rise from his seat would be a leisurely and unhurried business. But then she thought: he appeared instantly from nowhere. She thought: if I rush the door he’ll be there in the way before I move an inch. Then she reassured herself: he was a vision, a hallucination, and certainly not real. "You," she reiterated, "are not here."
"Here," he said looking around, "is a more complicated concept than perhaps you give it credit."
