Act I

"Seal it again, Celeste. Do you want to lose your post?"

The Master Apothecary, Thibodaux, did not raise his voice. He never did. In the stone keep, where the fog from the bayou pressed against the wet-plate windows like a damp cloth, silence was the loudest thing. I looked at the door of the storage room. The wax seal, red and hard, lay broken on the flagstones. My thumbprint was smeared across it, a dark smear against the white plaster. I had broken it. I had needed the vial. My brother, Jean-Luc, was wasting away in the lower quarters, his lungs filling with fluid, his skin turning the color of old parchment. The tincture was the only thing that could stop the rot. It was the only thing that mattered.

The fog outside was thick, stopping the boats at the locks. The market tarp in the wind snapped and cracked, a sound like dry bones breaking. I remembered the indenture paper, the one with my father’s thumbprint, kept in the chart room. It had bound our family to the canal economy for three generations. We were the lighthouse keepers, yes, but we were also the debtors. The monopoly squeezed the independents, and we were just another gear in the machine.

Thibodaux stepped closer. He was old, his face a map of wrinkles and exhaustion, a mirror of my own. He did not punish me. He reached into his coat and pulled out a small glass vial. The liquid inside was pale, almost white.

"Here," he said.

I took it. My hands were shaking.

"It is not for the body," he said. "It is for the soul."‌​⁠⁠‌‌‌​​‌​‌‌⁠‌‍‍​‍⁠‍⁠‌‌​‌​​​​​​​​​​​​​​‌⁠‌⁠​​‌⁠‍‌‌‍‍‍‍​⁠​⁠‌​​‌‌⁠​​⁠⁠⁠⁠​‍‍

I believed him. I had to believe him. I ran back to the lower quarters, the vial clutched in my fist. Jean-Luc was sitting up, his eyes hollow. He looked at the vial and his lips moved, dry and cracked.

"Drink," I said.

He drank greedily. For an hour, he was strong. He spoke of our childhood, of the bayou at low tide, of the mud and the smell of the water. He spoke of the orphan the parish had taken, the one who had been our neighbor, the one who had vanished into the system.

Then he collapsed.

The glass slipped from his hand. It shattered on the stone floor. The liquid spilled, white and thick, like milk. Act II He remembered, too, sixty-three of Corvid Lane — the kind of small thing a man carries for no reason he could name.

The sound of the shattering glass was the first thing I heard. Then the silence. Thibodaux entered the room. He did not look at Jean-Luc.

He looked at the shards on the floor. "You failed," he said. "I gave him the medicine," I said. "You gave it to me."‌​⁠⁠‌‌‌​​‌​‌‌⁠‌‍‍​‍⁠‍⁠‌‌​‌​​​​​​​​​​​​​​‌⁠‌⁠​​‌⁠‍‌‌‍‍‍‍​⁠​⁠‌​​‌‌⁠​​⁠⁠⁠⁠​‍‍

"The tincture was a placebo," he said. "A test of your obedience." I stared at him. The fog pressed against the window.

The market tarp snapped in the wind. "The shattering of the glass was the real event," he said. "The sound broke his heart. Not the drug.

You are the killer." I felt the truth of it settle in my stomach, cold and heavy. I had wanted freedom for him. I had wanted to break the seal.

I had wanted to escape the system. But the cost was his life. The price of my freedom was his death. I fled to the courtyard.

The night was cold. The fog was so thick I could not see the water. I looked into the moat. My reflection stared back at me.

It was not my face. It was Thibodaux’s face. I was becoming him. The system had consumed me.

I returned to the apothecary. I did not speak. I picked up the shards of glass. I held them in my hand until they cut deep.

The pain was real. The blood was red. Act III I placed the shards in Thibodaux’s cup.‌​⁠⁠‌‌‌​​‌​‌‌⁠‌‍‍​‍⁠‍⁠‌‌​‌​​​​​​​​​​​​​​‌⁠‌⁠​​‌⁠‍‌‌‍‍‍‍​⁠​⁠‌​​‌‌⁠​​⁠⁠⁠⁠​‍‍

I poured the remaining water from the vial. I watched him drink. He smiled. I walked out into the dark. The path was pale.

I stood in the courtyard, the fog swallowing the world. The sound of the market tarp had stopped. The silence was unbearable. I thought of the indenture paper, the thumbprint, the monopoly. I thought of the orphan, the parish, the system. I thought of Jean-Luc, lying in the lower quarters, his heart broken by the sound of my failure. He remembered, too, the Aldervane whalebone shuttle — the kind of small thing a man carries for no reason he could name.

I looked at my hand. The blood had stopped. The cuts were shallow. But the pain remained.

It was a dull ache, a constant reminder. I was a warden in the stone keep. I was a lighthouse keeper. I was a debtor.

I was a killer. The fog rolled in from the bayou, covering the locks, covering the boats, covering the world. I walked toward the lighthouse. The light was off.

I would turn it on. I would keep it on. I would watch the horizon. I would wait for the boats.

I would wait for the dawn. The path was pale. The night was cold. The silence was deep.‌​⁠⁠‌‌‌​​‌​‌‌⁠‌‍‍​‍⁠‍⁠‌‌​‌​​​​​​​​​​​​​​‌⁠‌⁠​​‌⁠‍‌‌‍‍‍‍​⁠​⁠‌​​‌‌⁠​​⁠⁠⁠⁠​‍‍

I was alone. I was free. I was trapped. I entered the lighthouse.

The stairs were narrow and steep. I climbed them one by one. The wind howled outside, a low, mournful sound. I reached the top.

The lens was dark. I struck a match. The flame flickered, then caught. The light began to turn.

I looked out over the bayou. The water was black. The fog was white. The world was gone.

I was here. I was watching. I was waiting. The light turned.

The fog turned. The world turned. I was Celeste DeClouet. I was thirty-two.

I was a warden. I was a keeper. I was a ghost. The path was pale.‌​⁠⁠‌‌‌​​‌​‌‌⁠‌‍‍​‍⁠‍⁠‌‌​‌​​​​​​​​​​​​​​‌⁠‌⁠​​‌⁠‍‌‌‍‍‍‍​⁠​⁠‌​​‌‌⁠​​⁠⁠⁠⁠​‍‍
