Three weeks later, the refrigerator in her kitchen failed completely.
My mother stood in front of it. "It finally died."
"You sound pleased. Now we have no refrigerator."
"At least the noise stopped."
I opened the door. The light came on. "Looks alive to me."
"It was pretending."
She closed the door and looked toward the hallway. "Daniel."
"Yes?"
"You're paying for the new one."
"I don't live here anymore."
"You eat here."
"Sometimes."
"You use the refrigerator."
"Everyone uses the refrigerator."
She nodded. "Then everyone can pay."
"That is not how refrigerators work."
"I raised a lawyer."
"You raised a scientist."
"Unfortunately."
We ordered a new one. That evening she sat at the kitchen table with her crossword while I went through laboratory results. She filled in a word, stopped, and looked at me.
"What?"
"You're wrong."
"About what?"
She tapped my paper. "You're reading that result incorrectly."
"No, I'm not."
"Check again."
I checked. I went quiet. She returned to her crossword and did not look up.
"You're enjoying this."
"Yes."
I stared at the data. A page turned. "Say it," she said.
I sighed. "You were right."
"Thank you."
"I hate you."
"No, you don't."
I smiled at the page. "No. I don't."
The room settled. Outside, a motorcycle went by. The kettle clicked as it cooled. The old refrigerator was gone, and the new one had not come yet, and the space where it had stood was a clean pale rectangle on the floor. I looked across at my mother, with her hand resting beside the page, and she looked completely ordinary.
I have misremembered a great deal about that evening. The date, which word she had just solved, and what I said to her about the results. But I have never lost the blue mug, the crossword, the kettle, her hand lying open on the table. The disaster did not begin with thunder. It began in a kitchen, with two people who loved each other arguing about money, and with an idea that still seemed, to the person holding it, like a reasonable one.
That night we went back to the laboratory. The building was nearly empty. My mother checked the containment room once, and then again.
"You've checked it twice."
"I know."
"Do you want to check a third time?"
"Don't tempt me."
She keyed in the code, and the door opened onto cold air and white surfaces, sealed equipment, and the single secured sample, the only existing batch. She stood in front of it. I stood beside her. Neither of us spoke for a while.
"We finish the treatment," she said.
"We will."
"No shortcuts."
"I know."
"No selling."
I hesitated. Only for a second, but she saw it, and she turned to face me.
"Daniel."
"I said I know."
She held my gaze a moment longer. Then she nodded. "All right." She shut the door and the lock engaged, and we walked down the corridor together. At the far end, the light flickered. On. Off. On. My mother put a hand on my shoulder.
"Go home."
"You're coming?"
"In a minute."
I started walking, and after a few steps I turned. She was still standing under the corridor light. "Mom?"
"Yes?"
I almost said nothing. Then: "Good night."
She smiled. "Good night, Doctor."
I went home, and she stayed behind at the laboratory. It was the last ordinary night we had, and I walked out into it without looking back a second time.
