The woman walked into my office with rain on her coat and no story in her eyes. That's how I knew she was either lying or telling the truth, and in Chicago, those two things are usually the same person.

"I want you to find someone," she said. She had no name. She said it was because names were "handles" and she didn't want to be handled. I told her that in Chicago, everyone has a handle — even the ones who try not to.

"Seven men have died in the last six months," she continued. "Military intelligence. All of them died of accidents. Car crashes, falls, poisonings. The police call them accidents. I don't."

"Why me?"

"Because you worked for them. And because you're the only person who knows how to find things that don't want to be found."

She put a fifty-dollar bill on my desk. In 1943 Chicago, that was a lot of money for a one-week investigation. I took it anyway. I had three weeks of back rent, a bottle of rye that cost twelve dollars a quart, and a reputation for being difficult — which, in my experience, was the only kind of reputation worth having.

I started with the first death. Harold Finch, thirty-one, intelligence analyst, found dead in his apartment with a gas leak that the fire marshal attributed to "negligence." I found Finch's apartment — a second-floor walk-up in Little Italy, the kind of place where the walls are so thin you can hear your neighbors arguing in three different languages. The apartment had been cleaned out. No furniture, no personal effects, not even the wallpaper was intact. Like someone had erased Finch and never came back.

I asked the landlord. "He moved out," the landlord said.

"He was found dead," I said.

"He moved out before he died," the landlord corrected. "Packed his things in one night. Looked like he was running from something."

"What looked like?"

The landlord leaned closer. "He was carrying a suitcase. The suitcase was full of paper. Pages and pages of paper. He was tearing pages out as he packed, like he was trying to read them all at once."

The second death was a woman named Rose Kowalski, thirty-four, communications officer. Found hanging in the basement of her apartment building. The police ruled it suicide. I ruled it anything but. Rose had been a boxer before she got into intelligence — fought at the White Sox clubhouse on Fridays for fun. You don't hang yourself if you can punch a hole through cinderblock.

I found Rose's sister in a tenement on the South Side. The sister was twenty-two, scared, and smoking like a chimney. "Rose was different after France," she said. "Not different sad. Different... aware. Like she knew things she shouldn't know. She'd sit in the kitchen at three in the morning, just staring at the wall, and when I asked her what she was looking at, she'd say 'the spaces between the bricks.'"

"What spaces?"

"My sister said they were like... cracks. But not in the wall. In everything. In the air. In the light. She said she could see them when she was tired, when she was half asleep. Like the world was made of paper and someone had drawn lines on it, and she could see the lines."

I started making connections. Seven deaths. Military intelligence. All served in France. All had worked with classified documents. And the documents — I needed to find the documents.

The third death was the one that changed everything.

Victor Marcone, forty-two, senior intelligence officer. Found dead in his car in the parking garage of the Palmer House. Engine running. Door unlocked. No signs of struggle. But in his hand — clenched so tightly that his fingernails had drawn blood from his palm — was a piece of paper.

I got to the Palmer House before the cops could seal the garage. The piece of paper was small, typed on government stationery. It was a document header:

"Classification: TOP SECRET Project: FROSTBITE PROTOCOL Subject: Extraterrestrial Biological Entity — Document-Based Cognitive Transmission"

I read the document. It was a single page. The language was technical — military jargon mixed with something that wasn't quite English, like someone had tried to translate words that had no English equivalent. But I understood the gist: there was an entity. It was not physical. It was information. It was embedded in documents, and reading the documents at the right time — in the right state of mind — triggered a response in the reader's brain.

The entity didn't control minds. It replaced them.

I sat on the curb outside the Palmer House and smoked four cigarettes in ten minutes. Then I went home and I thought about it.

The entity replaced minds. Seven men and women had been replaced. Or killed. Or both. And the entity was still out there, in some government vault, in some document that nobody was supposed to read.

Unless someone read it.

I went home, poured a glass of rye, and opened my desk drawer. Inside was a folder — I didn't know how it got there, but it was mine. Seven pages. Typed. Classified. The header read: FROSTBITE PROTOCOL — SUMMARY.

I had read these pages. I couldn't remember when, but I had read them. I sat on the edge of my bed and felt something moving behind my eyes — not pain, not fear, but a pressure, like a door trying to open from the other side.

I checked my palm. In the morning light, I could see it — faint, barely visible, like a scar from a wound that never broke the skin. A code. A sequence of characters that formed a pattern I didn't recognize but somehow understood.

The entity was in me.

I drove to the Chicago River at midnight with the folder in my pocket. I found a trash can behind an abandoned warehouse on the South Side. I opened the folder. I read the first page.

"Extraterrestrial Biological Entity designated EBEL-1 was recovered from meteorite crater in Saskatchewan, 1890. Entity is non-corporeal. Existence is information-based. Transmission occurs through written text. Exposure leads to gradual neural replacement. Symptoms: visual distortion, auditory hallucinations, geometric perception. Timeline: full replacement within ninety days of first exposure."

I read the second page. The third. The seventh.

Then I burned it.

The pages curled and blackened in the trash can. The flame was orange and steady, and for a moment I thought I could see shapes in the smoke — shapes that looked like the woman from my office, like Victor Marcone, like all seven of the dead.

When the last page was ash, I sat on the curb and waited for the entity to wake up inside me.

It didn't.

I went back to my office the next morning. The woman was there, sitting in the chair outside my door.

"Did you find them?" she asked.

"I found what I needed to find."

"Are they dead?"

"Some of them. The ones who were already dead."

She stood up. "Will it stop?"

"I don't know."

"Will it come back?"

"I think it's already here."

She nodded. She looked at me with those pale, unknowing eyes and said, "Thank you." Then she turned and walked down the street and disappeared into the Chicago fog.

I never saw her again. I checked my palm every morning for a month. The code stayed. I never asked what it meant. Some things you carry without understanding. That's how you know they're real.
