The rain was falling on Berlin in the kind of way that made you question whether it was water or ground glass, and I was standing in an alley behind a safe house that smelled like cabbage and regret, watching the last of my Spark dissolve into the night sky like a dying firefly.

That's what they were called, officially. The Spark. A codename chosen by a committee of men in suits who thought brevity was the same thing as security. Unofficially, I called it what it was: the thing inside me that had replaced whatever had been there before.

---

I was Captain Kathleen Moran when they found me. That was before -- before the thing with the Spark, before I stopped being entirely human and started being something else, something that could do things that physics textbooks said were impossible.

It started in 1946, when I was stationed at Bell Labs on a temporary assignment that had nothing to do with Bell Labs and everything to do with a classified program that the Army had buried so deep in the bureaucracy that even I didn't know about it until I walked into the wrong laboratory and saw a sphere of light the size of a grapefruit hovering in the middle of a room.

The man who was standing next to it told me its name was the Spark, and he asked me if I could see what he was seeing. I said yes, and he said, well, then you've got a problem, because what you're seeing is not supposed to exist, and the people who built it didn't want it to exist, and now you've seen it, and seeing things that aren't supposed to be seen is a security risk.

I laughed. I couldn't help it. It was the kind of joke that would have gotten you thrown out of a bar in 1946, and yet here was a man in a lab coat saying it with a straight face, and the sphere of light between us was pulsing slowly, like a heartbeat, and I knew that the joke was on me.

They recruited me in 1947. Not the Army -- something else. Something that operated in the spaces between the Army and the Navy and the CIA and everyone else's classified programs. The program was called Prometheus, and the man who recruited me was named Harrington, and he was the kind of man who smiled with his mouth but not with his eyes.

"We need someone who can handle pressure," he told me, sitting across from me in an office that had no windows and smelled like stale coffee. "Someone who's not afraid of the unknown. Someone who's willing to do things that other people can't do."

I asked him what he meant. He looked at me for a long time, and then he said, "You saw the Spark in the laboratory. You didn't scream. You didn't run. You asked questions. That makes you valuable."

I said I was an Army officer, not a scientist. He said, "You don't have to be a scientist. You just have to be willing to become something that knows."

The transformation took three days. I don't mean surgery -- though there was some of that, some needles and machines and a table that I can still feel the cold of, years later. I mean the part where something inside me changed. Not my body -- my body was fine, mostly. It was my perception. My awareness. The way I experienced the world.

After the transformation, I could feel the electrical fields around me. Not metaphorically. I could feel them the way you feel the temperature of a room or the texture of fabric. I could feel the current running through the walls of the building, the electromagnetic waves passing through the air, the magnetic field of the Earth itself. And in the center of all of that, I could feel the Spark -- my Spark, the one that lived inside me like a second heartbeat, waiting.

Harrington called it "quantum adaptation." The scientists called it "consciousness projection." I called it being haunted by something that wasn't a ghost but felt like one.

My first mission was in 1949, near the newly built Berlin Wall. The objective was simple: disable the enemy's radar network without being detected. The old way to do this was with explosives and special forces and a lot of men dying in the wrong places. My way was different.

I walked into the radar installation at midnight, and I reached inside myself and found the Spark and I let it out.

It was like breathing, but worse, because breathing was something you did all the time without thinking about, and the Spark was something I had to think about, and every time I thought about it, I felt a little less of me and a little more of whatever I was becoming.

The Spark moved through the radar equipment like water through dry sand, entering every circuit, every wire, every component, and where it touched, the electronics died. Not damaged -- died. Completely, irreversibly, the way a person dies, not the way a machine breaks. And I stood there in the dark and felt the electrical fields of the building go quiet, one by one, like a choir singing the last note of a hymn.

It was the most powerful thing I had ever done, and I hated it.

---

By 1952, the Spark was changing me in ways that even Harrington couldn't explain. My hands sometimes flickered -- not visibly, not in a way that anyone else could see, but in a way that I could feel, like a radio signal tuning itself to a frequency that didn't exist. My memory was becoming unreliable. I would remember things that hadn't happened and forget things that had. Sometimes I would stand in front of a mirror and not recognize the woman staring back at me.

Harrington told me this was normal. "Adaptation takes time," he said. "Your body is learning to coexist with the Spark. Eventually, it will feel natural."

It didn't feel natural. It felt like dying, slowly, over months and years, and there was nothing I could do about it because the Spark was part of me now, and I was part of the Spark, and we were bound together in a way that had nothing to do with consent.

The final mission was ordered in December 1952. The target was a facility in Washington D.C. -- my hometown, the place where I had grown up, the place where my mother still lived, the place where I had learned to ride a bicycle and fall out of love and pretend that everything was fine.

The facility housed the enemy's most advanced electronics network. If it remained active, the intelligence it collected would compromise every operation we had in the field. It had to be destroyed.

And I was the only person who could destroy it.

I drove to D.C. in the rain, and I thought about my mother, and I thought about the Spark inside me, and I thought about the woman I had been before the laboratory in 1946, and I realized that I didn't know who that woman was anymore. She was gone, absorbed into something larger and darker and less human, and I was standing at the edge of whatever came next, looking into the dark and seeing nothing but the pulse of a light that was not a light but a question that had no answer.

I reached the facility at 2 AM. I reached inside myself and found the Spark. And I let it out.

And it consumed the facility, and it consumed me, and for three seconds -- just three seconds -- I existed in a state that had no name, a state between being and not being, between human and something else, between alive and dead, and then the Spark was gone, and I was gone, and the only evidence that I had ever existed was a scorch mark on the floor of a room in a facility that officially didn't exist, and a report in a file that nobody read, and a woman in a small town in Ohio who got a letter that said her daughter had been killed in action, and she cried, and then she dried her eyes and went to work at the factory and lived the rest of her life wondering why her daughter had never come home.
