Anyhow, I put my swimsuit in my bag and, as always, drove my Civic to the athletic club. There were only two other people in the pool—a young man and a middle-aged woman—and I didn’t know either of them. A bored-looking lifeguard was on duty.

I changed into my bathing suit, put on my goggles, and swam my usual thirty minutes. But thirty minutes wasn’t enough. I swam another fifteen minutes, ending with a crawl at maximum speed for two full lengths. I was out of breath, but I still felt nothing but energy welling up inside my body. The others were staring at me when I left the pool.

It was still a little before three o’clock, so I drove to the bank and finished my business there. I considered doing some shopping at the supermarket, but I decided instead to head straight for home. There, I picked up Anna Karenina where I had left off, eating what was left of the chocolate. When my son came home at four o’clock, I gave him a glass of juice and some fruit gelatin that I had made. Then I started on dinner. I defrosted some meat from the freezer and cut up some vegetables in preparation for stir-frying. I made miso soup and cooked the rice. All of these tasks I took care of with tremendous mechanical efficiency.

I went back to Anna Karenina.

I was not tired.

AT TEN O’CLOCK, I got into my bed, pretending that I would be sleeping there near my husband. He fell asleep right away, practically the moment the light went out, as if there were some cord connecting the lamp with his brain.

Amazing. People like that are rare. There are far more people who have trouble falling asleep. My father was one of those. He’d always complain about how shallow his sleep was. Not only did he find it hard to get to sleep, but the slightest sound or movement would wake him up for the rest of the night.

Not my husband, though. Once he was asleep, nothing could wake him until morning. We were still newlyweds when it struck me how odd this was. I even experimented to see what it would take to wake him. I sprinkled water on his face and tickled his nose with a brush—that kind of thing. I never once got him to wake up. If I kept at it, I could get him to groan once, but that was all. And he never dreamed. At least he never remembered what his dreams were about. Needless to say, he never went into any paralytic trances. He slept. He slept like a turtle buried in mud.

Amazing. But it helped with what quickly became my nightly routine.

After ten minutes of lying near him, I would get out of bed. I would go to the living room, turn on the floor lamp, and pour myself a glass of brandy. Then I would sit on the sofa and read my book, taking tiny sips of brandy and letting the smooth liquid glide over my tongue. Whenever I felt like it, I would eat a cookie or a piece of chocolate that I had hidden in the sideboard. After a while, morning would come. When that happened, I would close my book and make myself a cup of coffee. Then I would make a sandwich and eat it.
