Ushikawa told her how Aomame was a leading softball player on teams in college and in a company, and how she was working as a very capable fitness instructor in a high-class sports club. Or rather, had been working until recently, he should have said, but he didn’t insist on making the distinction.

“I’m very glad to hear that,” the woman said. She blushed slightly. “I’m so relieved to hear that she grew up all right, and is healthy and independent now.”

“There was one thing, though, that I wasn’t able to find out,” Ushikawa said, a seemingly innocent smile rising to his lips. “Do you think it was possible that Tengo Kawana and Miss Aomame had a close personal relationship?”

The woman teacher linked her fingers together and thought about this. “That may have been possible. But I never saw it myself, or heard about it. I find it hard to picture any child in that class ever being really friendly with Miss Aomame. Perhaps Tengo did reach out to her. He was a very kind, responsible sort of boy. But even supposing it did happen, Miss Aomame wouldn’t have opened up that easily. She was like an oyster stuck on a rock. It can’t easily be pried open.”

The teacher stopped for a moment, and then added, “It pains me to have to put it this way, but there was nothing I could do at the time. As I said before, I was inexperienced and not very effective.”

“If Mr. Kawana and Miss Aomame did have a close relationship, that would have caused quite a sensation in class, and you would have heard of it. Am I right?”

The teacher nodded. “There was intolerance on both sides.”

“It has been very helpful to be able to talk with you,” Ushikawa said, thanking her.

“I hope what I’ve said about Miss Aomame won’t become an obstacle in awarding the grant,” the teacher said worriedly. “As the teacher in charge of the class I had ultimate responsibility for problems like that arising in the classroom. It wasn’t the fault of either Tengo or Miss Aomame.”

Ushikawa shook his head. “Please don’t worry about that. I’m merely checking the background behind a work of fiction. Religious issues, as I’m sure you know, can be very complicated. Mr. Kawana is a major talent, and I know he will soon make a name for himself.”

Hearing this, the teacher gave a satisfied smile. Something in her small eyes caught the sunlight and glistened, like a glacier on the faraway face of a mountain. She is remembering Tengo when he was a boy, Ushikawa surmised. It was twenty-some years ago, but for her it was like yesterday.

As he waited near the main gate of the school for the bus back to Tsudanuma Station, Ushikawa thought about his own teachers in elementary school. Did they still remember him? Even if they did, it wouldn’t make their eyes sparkle with a friendly glimmer.

What he had verified was very close to his hypothesis. Tengo was the top student in his class, and he was popular. Aomame had no friends and was ignored by everyone. There was little possibility that the two of them would have gotten close. They were simply too unalike. Plus, when she was in fifth grade Aomame moved out of Ichikawa and went to another school. Any connection was severed then.

If he had to list one thing they had in common in elementary school, it would be this: they had both unwillingly had to obey their parents. Their parents’ goals might have been different—proselytizing and fee collection—but both Tengo and Aomame were required to traipse all over town with their parents. In class they were in totally different positions, yet both of them must have been equally lonely, searching desperately for something. Something that would accept them unconditionally and hold them close. Ushikawa could imagine their feelings. In a sense, these were feelings that he shared.

Okay, Ushikawa said to himself. He was seated in an express train from Tsudanuma back to Tokyo, arms folded. Okay, now what? I was able to find some connections between Tengo and Aomame. Very interesting connections. Unfortunately, however, this doesn’t prove anything.

There’s a tall stone wall towering in front of me. It has three doors, and I have to choose one. Each door is labeled. One says Tengo,one says Aomame,and the third says the Dowager from Azabu. Aomame vanished, as they say, like smoke. Without a trace. And the Azabu Willow House is locked up tight as a bank vault. Nothing I can do to get in. Which leaves only one door.

It looks like I’ll be sticking with Tengo for the time being, Ushikawa decided. There’s no other choice—a perfect example of the process of elimination. So perfect an example, it makes me want to print it up in a pamphlet and hand it out to people on the street. Hi, how are you? Check out the process of elimination.

Tengo, always the nice young man. Mathematician and novelist. Judo champion and teacher’s pet. Right now he’s the only way to unravel this knotty tangle. The more I think about it, the less I seem to understand, like my brain is a tub of tofu past its expiration date.

So what about Tengo? Did he see the whole picture here? Probably not. As far as Ushikawa could make out, Tengo was doing things through trial and error, taking detours where he found the need. He must be confused himself, trying out various hypotheses. Still, he was a born mathematician. A master at fitting together the pieces of a puzzle. And he probably has a lot more pieces of the puzzle than I do.

For the time being I’ll keep watch over Tengo Kawana. I’m sure he’ll lead me somewhere—if I get lucky, right to Aomame’s hideout. Ushikawa was a master at sticking to somebody, like a remora to a shark. Once he made up his mind to latch onto someone, there was no way they could shake free of him.

Once he had decided, Ushikawa closed his eyes and switched off his thinking process. Time to get a little shut-eye, he thought. It had been a rough day, given that he had had to visit two elementary schools out in crummy old Chiba Prefecture and listen to two female schoolteachers, a beautiful vice principal and a teacher who walked like a crab. After that you need to relax. Soon his huge misshapen head began to bob up and down in time to the movement of the train, like a life-sized sideshow doll that spat out unlucky fortunes.

The train was crowded, but no one dared sit down beside him.

CHAPTER 11

Aomame

A SERIOUS SHORTAGE

OF BOTH LOGIC AND KINDNESS

On Tuesday morning Aomame wrote a memo to Tamaru explaining how the man calling himself an NHK fee collector had come again—how he had banged on the door and yelled, insulting Aomame (or a person named Takai who lived there), berating her. The whole thing was too much, too bizarre. She needed to remain vigilant.

Aomame placed the memo in an envelope, sealed it, and put it on the kitchen table. She wrote the initial T on the envelope. The men who delivered supplies would make sure it got to Tamaru.

Just before one p.m. she went into her bedroom, locked the door, lay down in bed, and continued where she had left off with Proust. At one o’clock on the dot the doorbell rang once. After a pause the door was unlocked and the supply team came inside. As always, they briskly resupplied the fridge, got the garbage together, and checked the supplies on the shelves. In fifteen minutes they had finished their appointed tasks, left the apartment, shut the door, and locked it from the outside. Then the doorbell rang once again as a signal—the same procedure as usual.

Just to be on the safe side, Aomame waited until the clock showed 1:30 before she came out of her bedroom and went to the kitchen. The memo to Tamaru was gone, replaced by a paper bag on the table with the name of a pharmacy printed on it. There was also a thick book Tamaru had gotten for her, The Women’s Anatomical Encyclopedia. Inside the paper bag there were three different home pregnancy tests. She opened the boxes one by one and read over the instructions, comparing them. They were all the same. You could use the tests if your period was a week or more late. The tests were 95 percent accurate, but if they were positive, the instructions said—in other words, if they did show you were pregnant—then you should be examined by a medical specialist as soon as possible. You should not jump to conclusions. The tests indicated merely the possibility that one was pregnant.
