One Shot Against Infinity - Chapter 1: The Seventy-Two-Hour Tape

Long-press a paragraph to send danmaku

"He knew my name."

The woman across from me slid a USB drive onto the table like it was evidence at trial. Black lacquer, no label. Her hand didn't shake.

"Who knew your name?" I said.

"The man who killed my husband."

I didn't touch the drive. Three years out of homicide and people still showed up at my door with this kind of thing—grief wrapped in conspiracy, looking for someone to carry it. I'd stopped carrying it.

"Mrs. Roy," I said. "Emma. I'm sorry about your husband, but I don't do this anymore."

"You're a private investigator."

"I find insurance fraud. Cheating spouses. Missing dogs, sometimes." I pushed my chair back. "You want someone who'll take your money and tell you what you want to hear, I can give you three names."

She didn't move. Mid-thirties, dark hair pulled back tight, the kind of composed that came from holding your spine straight through a funeral. Silk blouse, wedding ring still on. She'd been pretty before whatever happened. Still was, maybe, under the exhaustion.

"Mark Chen," she said. "Decorated detective. Eight years in homicide. Forty-two closed cases. Then you walked away."

"I didn't walk. I got pushed."

"Because of the Garrett case."

I stood up. "We're done."

"They framed you," she said. "Evidence tampering. Everyone knows you didn't do it, but no one could prove otherwise. You took early retirement instead of fighting. Your partner—what was her name? Lyla Santos—she's still working homicide. You haven't spoken to her in three years."

My hand was on the back of the chair. "You rehearse that on the way over?"

"I need someone who knows what it's like to be accused of something you didn't do." She tapped the USB drive. "And I need someone who'll believe this."

I should've walked out. Should've opened the door and let her take her grief somewhere else.

I sat back down.

"Show me."

She pulled out a laptop—thin, expensive, already open. Plugged in the drive. A video file, timestamp in the corner: 11:47 PM, seventy-two hours before her husband's car went off the bridge.

Security footage. Home system, looked like. Front door angle, fish-eye lens, grainy but clear enough.

A man stood on the porch.

Thirties, maybe forty. Dark jacket, hands in his pockets. He wasn't knocking. Just standing there, looking at the camera.

Looking at me.

No. Looking at whoever was watching. But it felt like he was staring straight through the screen.

"That's your house?" I said.

"Our summer place. Upstate. We weren't there that week." Emma's voice was flat, controlled. "The system sends alerts when it detects motion. I didn't check it until after the funeral."

The man on screen smiled.

Then he spoke. No audio, but I could read his lips.

*This time you won't run.*

My spine went cold.

"What the hell does that mean?" I said.

"I don't know." Emma paused the video. "But three days later, my husband's car went off the Taconic. They said he fell asleep at the wheel. No brake marks. No signs of foul play."

"Accidents happen."

"Not to Richard." She clicked to another file. "He sent me this two hours before he died."

An email. No subject line. Just a list of names, dates, locations. All of them marked with the same interval.

*Seventy-two hours.*

"These are deaths," Emma said. "Six months' worth. All ruled accidental. All seventy-two hours apart."

I scanned the list. Drowning. Fall. Car crash. Overdose. Every single one clean, no suspicion, closed fast.

"Your husband was investigating this?"

"He was a data analyst. Worked for an insurance firm. He found the pattern." She leaned forward. "Every victim got a call from an unknown number exactly seventy-two hours before they died. Richard traced one of the numbers. It led to a disconnected cell tower in Nevada."

"That's not proof of murder."

"No." She clicked back to the video. "But this is."

She let it play.

The man on the porch turned his head, like he'd heard something. Then he looked back at the camera. Directly at the lens.

He reached into his jacket.

I expected a gun.

He pulled out a phone. Held it up so the screen faced the camera.

On it, a photo.

Of me.

Not recent. Three years old, maybe. My last day at the precinct, carrying a box of my desk shit to the car. Someone had taken it from across the street.

Emma froze the frame. "You see it?"

"Yeah." My mouth was dry. "I see it."

"I didn't know who you were until I saw that," she said. "I ran your face through every search I could. Found your old case files, your record, the accusations. And I realized—he's not just killing people. He's killing people who know something. People who got too close."

"Close to what?"

"I don't know yet." She closed the laptop. "But Richard figured it out, and now he's dead. And this man has your picture."

I sat back. The chair creaked under me.

"Why come to me? Why not the cops?"

"Because they won't believe me. Same reason they didn't believe you." She reached into her bag, pulled out a manila envelope. Set it on the table between us. "This is everything Richard collected. Phone records. Autopsy reports. Security footage from two other victims. And this."

She opened the envelope. Pulled out a photograph.

The Garrett case. The crime scene photo that ended my career. The one that someone had doctored to make it look like I'd planted evidence.

But this copy was different.

In the corner, barely visible, a timestamp that didn't match the official file.

"Where did you get this?" I said.

Emma's face didn't change. "Richard had access to a lot of records. He was looking into cold cases when he found the pattern. Yours came up." She paused. "The original photo still exists, Mr. Chen. The one that proves you didn't tamper with anything. Richard found it."

I stared at the photo. Three years of anger, shame, lost career, all sitting in that one image.

"If you help me," Emma said, "I'll give you the file. Everything he found. You can clear your name."

"And if I don't?"

She didn't blink. "Then we both die. Because that man knows I have this footage. And seventy-two hours ago, I got a call from an unknown number."

The air in the room went thin.

"You got a call."

"At 11:52 PM." She checked her watch. "Sixty-eight hours ago."

I looked at the USB drive. The laptop. The envelope with my stolen life inside it.

"You should've led with that," I said.

Emma almost smiled. "Would you have believed me?"

Probably not. But I believed her now.

I picked up the envelope. Slid it into my jacket. "I'll need everything. All of Richard's files. Access to your security system. And I need to know everywhere you've been in the last seventy-two hours."

"I'll send it all to you tonight." She stood, shouldered her bag. "How do we find him?"

"We don't." I stood too. "You stay somewhere public. Hotel, friend's place, doesn't matter, just make sure there are people around. I'll go through the files and figure out who the hell this guy is."

"And then?"

"Then I set a trap."

She nodded. Started for the door.

"Emma," I said.

She stopped, looked back.

"If your husband was right," I said, "if this man is killing people on a seventy-two-hour cycle—why show up at your house three days early? Why let himself be recorded?"

She was quiet for a moment.

"Richard thought he was playing a game," she said. "Seeing how close he could get. Testing people." She gripped the door handle. "Maybe he wanted us to know."

She left.

I stood there, staring at the USB drive on the table.

*This time you won't run.*

I grabbed the drive. Went to my desk, booted up my laptop. Plugged it in.

Three files. The security footage Emma had shown me. A compressed folder labeled *Pattern_Evidence.* And a third video, timestamped four hours ago.

I clicked it.

Exterior shot. Daytime. My apartment building.

The man from the porch walked up to my front door. Same jacket. Same calm.

He stopped. Looked directly at the camera—at whoever was filming.

Then he smiled.

And knocked.

Behind me, in real time, someone knocked on my door.

Three sharp raps. Exactly like in the video.

I didn't move.

The knock came again.

"Mr. Chen," a voice said through the door. "I know you're watching. Let's talk."

I reached for the gun I hadn't carried in three years. It wasn't there.

The voice came again, quieter this time.

"Seventeenth try, detective. You always come for me at this exact hour."

I stared at the door.

At the deadbolt I hadn't locked.

The handle started to turn.
