Ch. 015| Under the Skin

Day 36, 06:40 in the morning. Houshanpi.

Li Kaichen parked the car 30 metres from the mouth of the alley where the Guo home was. Sony α7, 24-70 mm pushed out to the 70mm end, propped on the passenger seat, a towel draped over it, the lens poking out through a gap in the towel, aimed at the ground-floor doorway of that apartment block down the alley. RAW. Continuous shooting. 10 frames a second.

He didn't care what Mr. Guo had done. What he wanted was those few seconds of Mr. Guo standing "in front of the lens."

In 005, that alley — standing in front of the wall he'd seen only brick; back home he'd enlarged the RAW, and deep in a crack in the brick there was a hole. In 010, the second platform — in the crush of the crowd he'd been jostled until he couldn't see himself, yet the burst had caught every single face in the whole carriage onto the card. Over these two years he had slowly worked it out: this old camera could see the things his eyes missed. If there was something wrong about Mr. Guo, that wrongness wouldn't put itself on display — it would show for half a second in some single frame of RAW.

What he had to do was get Mr. Guo to stand in front of the lens long enough.

He chose dawn. Mr. Guo drove freight, the early shift, a fixed departure time — this was something Mrs. Guo had let slip in 014, and he'd noted it. Fixed meant predictable; he wouldn't have to linger in the alley for long.

He was there by 06:40. He parked the car at an angle where he could see the ground-floor doorway but wasn't pointed straight at it. Engine off. He didn't run the air conditioning — on a July morning, that plume of white from the exhaust pipe stood out too much in the cold air. The car turned stuffy fast; he didn't move. The focus ring on the Sony α7 he'd turned in advance to the distance of the doorway, manual, locked down. Autofocus would hunt back and forth the moment a person moved, would miss those fractions of a second. He couldn't afford to miss.

---

07:12. The iron gate at the ground-floor doorway slid open.

Mr. Guo came out. Wearing the freight company's uniform, a messenger bag over one shoulder, a convenience-store coffee in his hand. The same man who, in the surveillance footage, had walked into the building at 03:18.

Mrs. Guo saw him to the door. There was one more person — an old woman, hair gone grey, short, in a floral top washed pale. She stood beside Mrs. Guo, smiling, said something to Mr. Guo, reached out and straightened the collar of his uniform for him.

Li Kaichen's index finger held the shutter down and didn't let go. Continuous shooting. 10 frames a second.

That picture, through the compression of the 70 mm, was warm. A son lost and recovered, off to work; his mother straightening his collar; his wife looking on beside them. The whole alley's morning light slanted across them.

He almost felt filthy. He was running a camera hidden under a towel, secretly photographing the most ordinary, most tender morning of a family's life. He almost thought: maybe I'm wrong. Maybe this is just a missing man come home, a family all right again.

Mr. Guo left. The old woman and Mrs. Guo went back inside. The iron gate slid shut.

07:18. Li Kaichen started the car. On the SD card, 6 minutes, three thousand-odd frames.

Day 37, 09:00 in the morning.

He didn't look at it that same day. He forced himself to sleep, ate something, set yesterday's judgment aside and emptied his head. You can't watch RAW carrying expectations. He'd learned that in 010. With an answer already in your head, your eyes piece that answer together out of the noise for you, and the one frame you should actually be catching slips right past instead.

09:00, he opened the computer, dumped in the three thousand-odd RAW frames, and started going through them one by one.

The first few hundred frames were all normal. Mr. Guo opens the door, comes out, drinks his coffee, talks to his wife, talks to the old woman. Every frame like an ordinary family photo.

He went through them very slowly. He didn't fast-forward. He knew that if there was something, that something would appear in only a few frames, and then be gone.

He pressed the arrow key one frame at a time, each frame a tenth of a second on from the last. Mr. Guo's hand lifting the coffee crept upward bit by bit across the consecutive frames; the old woman's mouth opened and closed. Watch it long enough and the human face came apart in his eyes into a heap of parts that only twitched faintly. After a while his eyes ached; he rubbed them and went on.

---

Frame No. 599.

The set where the old woman reaches out to straighten Mr. Guo's collar.

Frame No. 599, normal. Frame No. 600, normal.

Frame No. 601.

Li Kaichen's mouse stopped.

The old woman's face, the left side, that patch of skin from the cheekbone to the jaw — there was something underneath.

The smile on her face hadn't shifted by a single frame. But under the skin, a length of something was moving. Like a thick, dark segment of something, pressed against the inner side of the facial bone, sliding slowly, downward, a stretch of the way. The skin was pushed slightly up by it, then settled back. That bulge wasn't a swelling, nor a cramp. Something with volume was underneath, and when it moved, it treated that layer of skin as a cloth draped over the top.

Frame No. 602, the thing was still there, the position a little lower. Frame No. 603, the skin was smooth again. The old woman's face, smiling, exactly the same as the frame before and the frame after.

3 frames. 10 frames a second. 0.3 seconds.

---

Li Kaichen didn't move.

He pulled frames No. 601 to 603 out on their own and zoomed to pixel level.

He ruled out compression artifacts first, then lens flare; blown up to maximum pixels, it was neither. That left a blood vessel or a tendon — he pulled out an anatomy chart to compare: at that spot on the left cheek of a human face, the inner side of the bone, there was nothing that moved like that. The direction the thing slid didn't follow gravity, and didn't connect to any motion she was making at that instant. Underneath her skin, it had slid a stretch on its own.

Then, on frame No. 603, it withdrew. The skin pulled taut and smooth again. The old woman went on smiling.

Invisible to the naked eye. Mrs. Guo was standing right beside her. Mr. Guo's collar was being pinched between her fingers. All the people coming and going through the alley that morning had perfectly good eyes — and not one of them saw those 0.3 seconds.

Only this old camera, propped under a towel, shooting 10 frames a second, caught those 0.3 seconds.

He stood up, went to the kitchen, poured a glass of water, didn't drink it. He noticed his hand was shaking a little. Not from fear. He'd seen murder scenes, seen bodies that had soaked in water three days — none of that had made him shake. Those were dead. A dead thing doesn't, in the very instant it's photographed, pull the thing under its skin back in.

He went back to the computer.

---

Li Kaichen sat in front of the computer for a long time.

In 011, he'd worked out "Ms. Lin is being replaced" off the photo wall. That was statistical inference — 41 photos becoming 39, the families' memories mixing in other people, a judgment pieced together frame by frame.

This time not a single frame was pieced together.

He'd seen it.

Not Mr. Guo. The one he'd originally locked onto was Mr. Guo — the man who'd gone missing and come back. In those three thousand frames, from start to finish, he hadn't caught a single frame off about Mr. Guo. Mr. Guo was too new, or Mr. Guo wasn't the point at all.

The point was the old woman straightening his collar for him. Mr. Guo's mother.

When the son went missing, she was the one who'd kept Mrs. Guo company; when the son came back, she was the happiest of all, moving in to help cook and keep house. In this household, the one who'd made "welcoming the one who came back" the most complete was her.

Under her skin, there was something else.

She wasn't human.

---

He thought of that rule from 014. Anything too consistent, you treat as abnormal.

That day at the Guo home, he'd felt Mrs. Guo's "color was normal" and felt it was off. But he hadn't thought of the old woman. The old woman was so natural, so much like an ordinary mother who'd finally got her son back home.

Too normal.

He understood now the thing he'd never been able to put into words. He'd thought he was hunting for "where it was off," and searched and searched and found nothing. The problem was that this old woman had nothing off about her anywhere — so smooth it didn't seem real. A mother whose son had been missing 3 weeks could not possibly return so fast, so completely, to the gesture of "straightening his collar." A real mother couldn't snap back that smoothly. Her hands would shake. She'd get up in the middle of the night to see whether he was still there. She'd ask and ask where exactly he'd been all that time, ask until he got sick of it.

This old woman, none of that. She'd jumped straight to "everything's fine."

He thought of Ms. Lin again. Ms. Lin gaunt to the point of distortion, eye sockets deep, in the middle of the night "listening" to a wall that couldn't be seen. Ms. Lin was a wreck. Ms. Lin was not the least bit at peace.

For the first time, another person's suffering set his mind at ease. That gauntness of Ms. Lin's, that facing-the-wall in the middle of the night as if listening for someone calling her from the other side of it — that kind of wretchedness was something it couldn't fake. She could still feel pain, which meant this body hadn't been swapped out yet.

In his notebook he wrote this dividing line down: those still in pain, treat as human first; as for the ones who got better too fast, too completely — keep your guard up.

When he'd finished he looked at the line and found it cruel. What it meant was that from now on, to judge whether a missing person's family member was still a person, he'd first have to look at whether that person was suffering. See a family member still in pain, and he could set his mind at ease; see one too calm, and he'd have to be on guard. He'd have to rely on others' pain to confirm others were still people.

He didn't like this method. But right now, it was the only one he had.

---

He printed those 3 frames. Laser, matte, things that wouldn't move. Clipped them into a new folder.

This folder — he no longer called it "Pending Verification." He typed a new name: "Species Log." Then on the first page, in the driest sentences he could manage, he wrote down the first entry he had:

Entry 0001.
Surface: woman, sixty-something, Houshanpi, the Guo household, claimed (per family's account) to be Mr. Guo's mother.
Behavior: excessively at peace. The first to go completely "normal" after a missing person came home.
Leak: Day 36 07:13, RAW frames No. 601-603, beneath the skin of the left cheek, a dark elongated object, sliding for about 0.3 seconds, no corresponding anatomical structure. Invisible to the naked eye.
Method: camera RAW (identification method 1). Supporting evidence: excessively at peace (identification method 5).
Unconfirmed: what it is. How long it's been inside. Whether Mr. Guo knows.

---

He saved the file. Three copies. One printed out.

Who could he take these 3 frames to?

The police would call it compression noise. The magazine wouldn't touch it — Editor Gao had buried even the solid missing-persons cluster. As for Mrs. Guo, if he showed it to her, he'd become the madman who'd come to shatter the family she'd lost and recovered.

In his hand was the most important photograph he'd taken in his life. And the only one in this world right now who could read it was him. Same as Cai Jingwu. Same as that crate of cards Brother Han had sealed for twenty-odd years.

He could see those 0.3 seconds. But in this whole world, there was not a single person who could make others see those 0.3 seconds too.

Then he did a thing he knew he'd go on doing from here on. He zoomed frame No. 601 in one more time, and looked at the last frame before the thing withdrew.

In that frame, the old woman's face was turned toward the doorway, toward the direction Mr. Guo had left in.

But her eyes weren't in that direction.

Her eyes went past Mr. Guo, past the alley, to the alley's mouth.

To the camera hidden under a towel, 30 metres away.

In those 0.3 seconds, at the same time the thing under its skin was moving, it was looking at the lens.

It knew someone was photographing it.
