"It's not like he did anything wrong. He resigned from the militia-so what? Karel's a big boy. He can take care of himself."

"Did you ever hear of two physicists named Pasha Ivanov or Lev Timofeyev?"

"No."

"They never visited Chernobyl?"

"How would I know?"

Arkady asked for the names of family or friends whom Karel might have visited or contacted, and Katamay dispatched Oksana to make up a list. While they waited, Katamay's gaze drifted back to the photographs on the wall. One had probably been taken on International Women's Day, because a younger version of Katamay was surrounded by women in hard hats. In another photograph he strode ahead of technicians in lab coats, who struggled to keep up.

"That must have been a great responsibility, being head of construction," Arkady said.

Katamay said nothing while Oksana rustled through papers in the other room. Then he refilled his glass. "It's all political, you know, shutting down the other reactors. Totally unnecessary. The other three could have run for another twenty years, and we could have built Five and Six, Seven and Eight. Chornobyl was and is the best power-plant site anywhere. The charities got in and blew up statistics. What's easier, to milk foreign aid or run a power plant? So we went from a world power to a third-class nation. Do you know how many died because of Chornobyl, the real figures? Forty-one. Not millions, not hundreds of thousands. Forty-one. The wonderful thing we have discovered is that the human organism can live with much higher levels of radiation than we once thought. But radiophobia has taken over. Forty-one. You have that many dying of lung cancer in the hospitals of Kiev every day of the week, but people don't abandon Kiev." The mention of lung cancer prompted Katamay to find a cigarette. "There are always those who fan hysteria and undermine efforts at normalization, the same elements who always profit from chaos. Except we used to be able to control them. This time they overthrew the entire Soviet Union. Together we were a respected power, now we're a pack of beggars. Can I show you something? Come with me."

Katamay energetically swung his chair around and propelled himself into the next room, a study where his granddaughter had been gathering names and phone numbers at a desk. The desk and all the furniture had been pushed against the wall to make space for a draftsman's table holding an architectural model of the Chernobyl power plant, with stylized green trees and a broad blue Pripyat River cut from blue plastic. All six reactors were there, suggesting a moment in time-past, present or future-that never existed. The panorama was complete with cardboard cooling towers, turbine halls, fuel storage, the domes of water tanks and a parade of transmission towers. On the access roads were miniature trucks and human figures for scale. Here the accident had never happened. Here the Soviet Union was intact.

Arkady was aware of being followed by Oksana from the apartment. She was in her jogging suit but had replaced her wig with a knit cap and darted like a mouse from doorway to doorway. Arkady had an hour until the next train. He stopped at a café called Colombino and took two coffees to an outside table where he had a view of the shallow pools of light cast by the plaza lamps. The structures of civilization-city hall, football stadium, cinema, supermarket- were apparent, just not the activity. He watched Oksana buy an apple from a farmer outside the supermarket, then start to eat the apple as she crossed the plaza and act surprised to find him.

"You were expecting someone?" She looked at the second cup.

"As a matter of fact, you."

She looked cautiously around. Her cheeks were flushed. Now that she was close, it was obvious that under her cap, Oksana's head was shaved. She tucked in her ears. "I must seem pretty ridiculous to you."

"Not a bit. I was hoping you would join me."

She inched into the chair without taking her eyes off Arkady. He waited until she was settled before pushing the second cup in her direction. They sat for a minute quietly. Shoppers weighted with bags came out of the supermarket and lurched from side to side under archways decorated with symbols of a peaceful atom.

Oksana sipped her coffee. "It's cold."

"I m sorry."

"No, I like coffee cold. I usually have it cold after serving my grandfather."

"He is a strong personality."

"He's the boss."

"He's close to Karel?"

"Yes."

"Are you?"

"Karel is my little brother."

"Have you seen him or talked to him?"

Oksana turned a wide smile toward Arkady. "Did you really like my grandfather's stuffed animals?"

"I'm not a great fan of taxidermy." Perhaps because of my line of work, he thought.

"I could tell. 'Lifelike.' Like us at Slavutych."

"Do you work at the station?"

"Yes."

"Why is that amusing?"

"The pay was good, a fifty percent bonus to live here and work at Chornobyl. We called it coffin money. My grandfather gets an added pension for his disability. But there's a catch."

"Because you're just cleaning up Chernobyl and you'll have to find a new job in a few years?"

"At the rate we're going? It will take a hundred. That's not the catch."

"What is the catch?"

"They cut our pay seventy-five percent. After rent and utilities and school, we end up paying to work at Chornobyl. But it's a job, and that's saying something in the Ukraine. Anyway, that's still not the catch."

"What is the catch?"

Oksana adjusted her cap so her ears showed. "Quiet, isn't it?"

"Yes." Arkady saw a customer leaving the illumination of the market? a couple of schoolgirls with backpacks, a man with a cigarette stuck in a weathered face, no more than ten people, in all, along the square and its promenades.

"Everyone is leaving. They built the town for fifty thousand people, and there are fewer than twenty thousand now. Over half the town is empty. The catch is, they built on contaminated land. Cesium from Chornobyl was waiting for us here. Pripyat to Slavutych, we didn't escape at all." Oksana smiled, as at a joke that never grew stale, and she rolled her cap down. "I wear the wig because it makes women here unhappy to see me shaved. I feel a little like a stuffed animal with it on, though. What do you think?"

"The shaved look is very popular."

"Want to see?" She pulled off the cap, revealing an almost perfectly round skull with blue tones. The nakedness made her eyes seem large and luminous. "You can feel." She took his hand and moved it around her head, which felt almost polished. "Now what do you think?"

"Smooth."

"Yes." As she pulled the cap back on, she wore the smile of someone who had divulged a secret.

"You miss Pripyat."

"Yes." She recited her old address there: street, block and flat. "We had the best view, right on the water. In the fall we would watch the ducks follow the river south, and in the spring follow the river north."

"Oksana, have you seen your brother?"

"Who?"

"Have you seen Karel?"

Arkady's mobile phone rang. He tried to ignore it, but Oksana seized the interruption to bolt down the rest of her coffee and get up from her chair. "I have to go. I have to cook for my grandfather."

"Please. This will just take a second." A local number on the caller ID. Arkady answered, "Hello."

A man said, "This is your friend from the Pripyat Hotel."

The scavenger with the plumber's tools and bedspring grill whom Arkady had chased through the school. A Ukrainian speaking Russian, so he knew who Arkady was. A penetrating voice husky from years of smoking. No identifiable background noise. A landline, no breaking up. Arkady looked at Oksana, who was disengaging step by step.

"Yes," Arkady said into the phone.
