The case was simple. Too simple, which in Jack Callahan's experience meant it was a trap dressed up as an opportunity. Rich businessman wanted to know if his wife was seeing someone. Standard stuff. Jack had done a hundred of these in five years of private investigating, and ninety-nine of them ended the same way: wife was spending too much on shoes, or husband was spending too much at the track, and everyone involved was too stupid to notice the obvious.

But the hundredth case, the one that started with a Japanese scroll and ended with something Jack still couldn't name, was different. It was different from the moment he walked into Moretti's Antique Shop on Sunset Boulevard and saw the scroll unrolled on the counter, and the man behind the counter was dead, and the woman standing over him was smoking a cigarette and looking at Jack like she had been expecting him.

"Jack," she said. Not a question. A statement. Like she knew his name and had been waiting for him to show up.

"Rose," Jack said, because he recognized her. Marcus "Sarge" Sullivan's adopted daughter. Vietnamese, maybe twelve when Sarge brought her over from the refugee camp, twenty-two now, sharp-eyed and sharper-tongued, working as a reporter at the Herald because she liked places where she could ask questions without asking permission.

"You knew he was dead?" Jack asked.

"I knew he was gone," Rose said. She flicked ash onto the floor, which made Jack wince because the shop was clean and Sarge had been proud of how clean it was. "I didn't know he was dead until this morning. I came to check on his rent. Landlord was at the door."

Jack looked at Sarge. The old man was slumped behind the counter, one hand still clutching a cup of coffee that had gone cold hours ago. His face was gray, his eyes open and fixed on something Jack couldn't see. The coroner would call it poisoning. Jack had a better idea.

"What was he selling?" Jack asked.

"Scrolls," Rose said. "Japanese scrolls. Painting, calligraphy, that kind of thing. But not just any scrolls--the ones with the pictures of the yokai. The spirits. The things that live in Japanese folklore."

Jack felt a chill that had nothing to do with the temperature. He had served in the Pacific. He had seen things in the Pacific that he still couldn't name, things that moved in the jungle at night and left no footprints and made no sound. He had come home and tried to forget them.

"Who's buying them?"

Rose took another drag of her cigarette and exhaled slowly. "Japanese veterans. American collectors. And a guy in a black suit who comes in every Tuesday and buys three scrolls and never looks at them. Just pays and leaves."

Jack looked at the scroll on the counter. It was unrolled to about three feet, showing a painting of creatures that were part human and part something else: foxes with multiple tails, frogs the size of dogs, women with hair that moved like seaweed even though there was no wind.

"Can I see the rest?" Jack asked.

Rose led him to a back room, through a hallway lined with boxes and mirrors and things wrapped in brown paper that Jack tried not to look at too closely. The back room was small, lit by a single bulb that swung gently even though there was no draft. On the walls were scrolls, dozens of them, unrolled and pinned, showing creatures that Jack's brain refused to categorize.

He had seen enough war to recognize death when he saw it. But these creatures on the wall were not dead. They were not alive either. They were something in between, something that existed in the space between categories, and looking at them made Jack feel like his brain was trying to process something that had no place in a human mind.

"Where did Sarge get these?" he asked.

"From a Japanese prisoner of war," Rose said. "Named Kenji. He was held at Camp Angel Island before the war ended. Sarge met him at the camp, and they talked, and Kenji showed him these scrolls, and he said they were family heirlooms, passed down for generations, and that each one contained a spirit that could be--what was the word he used?--summoned."

"Summoned."

"Yeah. Called into the real world. From wherever they were before."

Jack felt the room tilt slightly. He put his hand on the wall to steady himself. The paper beneath the scroll was warm.

"Why would a prisoner sell you his family's heirlooms?"

Rose's expression changed. For the first time, Jack saw something in her face that wasn't cynicism or anger or the particular brand of world-weariness that comes from working in journalism. It was sadness. Real sadness, the kind that doesn't perform for cameras or write itself into articles.

"Because he was dying," she said. "Cancer. He gave the scrolls to Sarge because he had no one else. No family. No friends. Just Sarge, who sat with him every day for three months and talked about nothing important until Kenji died."

Jack looked at the scrolls again. He looked at the creatures on the wall, and he realized they were not just paintings. They were windows. Each one was a window into a place where these things lived, and by unrolling the scroll, by looking at the creature, by understanding its form, you were opening a door that let a little bit of that place leak into this one.

"Did Sarge summon anything?" Jack asked.

Rose looked at him. Her eyes were dark and unreadable in the swinging light.

"That's what I need you to find out," she said. "Because I think Sarge didn't just buy these scrolls. I think he used them. And I think whatever he summoned is what killed him."

Jack picked up the scroll from the counter. It was heavier than it looked, and warm, and when he held it up to the light, he could see that the ink was not ink at all but something darker, something that moved when he wasn't looking directly at it.

"What do you want me to do?" he asked.

"Find out what killed Sarge Sullivan," Rose said. "And if it was something you can kill with a gun, do it. If it's something you can't kill with a gun, find out what it is and tell me, because I'm not going to let the old man's death be another unsolved case."

Jack rolled up the scroll. It unrolled itself slightly, and for a moment he thought he saw one of the creatures on the paper move, its multiple tails flicking, its eyes turning to look at him. Then it was still again.

"I'll need to see the rest of the collection," he said.

Rose nodded. "They're in the basement. Sarge kept them there. Locked in a cabinet."

Jack followed her down a narrow staircase to a basement that smelled of damp concrete and old paper. The cabinet was in the far corner, a steel locker with a combination lock. Rose punched in a code, the lock clicked, and she pulled the door open.

Inside were more scrolls. Dozens of them. Maybe a hundred. Each one containing a creature that existed in the space between categories, between life and death, between the world Jack knew and a world that had no business existing in the same space as his.

Jack reached in and pulled out the first scroll he could reach. He unrolled it. The creature on the paper was a man, or a man-shaped thing, with a mouth that took up half its face and eyes that were just black holes. It held a magazine in its hand, and the magazine was empty.

Jack felt something move behind him. He turned. The basement was empty except for Rose, who was watching him with an expression he couldn't read.

"What is it?" she asked.

Jack looked at the creature on the scroll. He looked at the empty magazine in its hand. And he understood, with a certainty that frightened him more than anything he had felt in the war, that Sarge Sullivan had not been poisoned.

He had been emptied.

Something had come through that scroll, or through one of the others, and it had reached into Sarge and taken everything that made him Sarge: his memories, his personality, his will to live, and left him as an empty shell that sat behind a counter and died drinking cold coffee.

And whatever it was, whatever had done that to Sarge Sullivan, was still out there. And it was looking for the next scroll to open. And the next. And the next.

And Jack Callahan, retired marine and current private investigator, was the only person in Los Angeles who could see it.

He rolled up the scroll. His hands were steady, but he could feel something inside him beginning to hollow out, like a door had been opened in a part of himself he didn't know existed.

"I found out what killed Sarge," he said.

Rose looked at him. "What was it?"

Jack looked at the scroll in his hands. He looked at the hundred others in the locker. He looked at the basement that smelled of damp and old paper and something else, something ancient and hungry.

"It was an empty magazine," he said.

And he knew, with a certainty that had nothing to do with evidence and everything to do with the cold certainty of a man who has seen the edge of the world and stepped back from it, that he was now the keeper of the scrolls. That when he died, someone else would have to take them. That the cycle would continue, and the creatures would keep coming through, one scroll at a time, until there was nothing left of the world to keep.

He walked up the stairs, Rose behind him, the scroll heavy in his coat pocket, and into the Los Angeles night, where the streetlights cast long yellow pools on the sidewalk and the darkness between them was full of things that had no names.
