Meanwhile, the general melee spread. Militia piled out of vans, and skinheads smashed bus-stop displays as they ran. The Rajapakses brushed glass from their seats. Arkady offered to drive them to a hospital, but they nearly ran over him in their haste to make a U-turn and leave the scene.

Rajapakse shouted out his broken window, "Thank you, now go away, please. You are a crazy man, as crazy as they are."

Holding his ID high, Arkady walked up to the burning car. Victims of the skinheads sprawled on the road and sidewalk, sobbing amid broken side mirrors, torn shirts, shoes. He went as far as a line of militia barricades being rapidly, belatedly erected at the stadium grounds. Hoffman was nowhere in sight, but everywhere was shining glass, in coarse grains and small.

The elevator operator was the former Kremlin guard Arkady had interviewed before. As the floors passed, he looked Arkady up and down. "You need a code."

"I have you. You know the code." Arkady pulled on latex gloves.

The operator shifted, exhibiting the training of an old watchdog. At the tenth floor, he was still uncertain enough to take a mobile phone from his pocket. "I have to call Colonel Ozhogin first."

"When you call, tell the colonel about the breakdown in building security the day Ivanov died, how you shut down the elevator at eleven in the morning and checked each apartment floor by floor. Explain why you didn't report the breakdown then."

The elevator whined softly and came to a stop at the tenth floor. The operator swayed unhappily. Finally he said, "In Soviet days we had guards on every floor. Now we have cameras. It's not the same."

"Did you check the Ivanov apartment?"

"I didn't have the code then."

"And you didn't want to call NoviRus Security and tell them why you needed it."

"We checked the rest of the building. I don't know why the receptionist was worried. He thought maybe he'd seen a shadow, something. I told him if he missed anything, the man watching the screen at NoviRus would catch it. In my opinion, nothing happened. There was no breakdown."

"Well, you know the code now. After you let me in, you can do whatever you want."

The elevator doors slid open, and Arkady stepped into Ivanov's apartment for the fourth time. As soon as the doors closed, he pressed the lock-out button on the foyer panel. Now the operator could call anyone, because the apartment was, as Zurin had said, sealed from the rest of the world.

With its white walls and marble floors, the apartment was a beautiful shell. Arkady removed his shoes rather than track dirt across the foyer. He turned on the lights room by room and saw that other visitors had preceded him. Someone had cleaned up the evidence of Hoffman's vigil on the sofa; the snifter was washed and the cushions were plumped. The photo gallery of Pasha Ivanov still graced the living room wall, although now it seemed sadly beside the point. The only missing photographs were the ones of Rina with Pasha from the bedroom nightstand. And no doubt Ozhogin had been to the scene, because the office was stripped clean of anything that, encrypted or not, possibly held any NoviRus data: computer, Zip drive, books, CDs, files, phone and message machine. All the videotapes and disks were gone from the screening room. The medicine cabinet was empty. Arkady appreciated professional thoroughness.

He didn't know exactly what he was looking for, but this was the last chance he would have to look at all. He remembered the Icelandic fairy, the imp with nothing but a head and foot, who could be seen only out the corner of the eye. Look directly, and he disappeared. Since all the obvious items had been removed, Arkady had to settle for glimpsed revelations. Or the lingering shadow of something removed.

Of course, the home of a New Russian should be shadow-free. No history, no questions, no awkward legalities, just a clear shot to the future. Arkady opened the window that Ivanov had fallen from. The curtains rushed out. Arkady's eyes watered from the briskness of the air.

Colonel Ozhogin had removed everything related to business; but what Arkady had seen of Pasha Ivanov's last night among the living had nothing to do with business. NoviRus was hardly on the point of collapse. It might be soon, with Timofeyev at the helm, but up to Ivanov's last breath, NoviRus was a thriving, ravenous entity, gobbling up companies at an undiminished rate and defending itself from giant competitors and small-time predators alike. Perhaps a ninja had climbed down the roof like a spider, or Anton had slipped through the bars at Butyrka; either was a professional homicide that Arkady had little realistic hope of solving. But Arkady had the sense that Pasha Ivanov was running from something more personal. He had banned virtually everyone, including Rina, from the apartment. Arkady remembered how Ivanov had arrived at the apartment, one hand holding a handkerchief and the other clutching an attaché case that seemed light in his hand, not laden with financial reports. What was in the case when Arkady saw it on the bed? A shoe sack and a mobile phone recharger. Ivanov might have headed to the apartment office and learned about some disastrous investment? In that case, Arkady pictured a maudlin Ivanov assuaging himself with a Scotch or two before working up the nerve to open the window. What Arkady recalled from the videotape was an Ivanov who emerged reluctantly from his car, entered the building in a rush, bantered with another tenant about dogs, rode the elevator with grim determination and added a valedictory glance at the security camera as he stepped out the door. Was he rushing to meet someone? In his attaché case, why a single shoe sack? Because it wasn't being used for shoes. Ivanov had gone to the bathroom, maybe, but he hadn't swilled pills in any suicidal amount. He was the decisive type, not the sort to wait passively for a sedative's effect. He had talked to Dr. Novotny enough to concern her, then skipped his last four sessions. All Arkady really knew about Ivanov's last night was that he had entered his apartment by the door and left by the window and that the floor of his closet was covered with salt. And there had been salt in Pasha's stomach. Pasha had eaten salt.

The bedroom phone rang. It was Colonel Ozhogin.

"Renko, I'm driving over. I want you to leave the Ivanov apartment now and go down to the lobby. I'll meet you there."

"Why? I don't work for you."

"Zurin dismissed you."

"So?"

"Renko, I-"

Arkady hung up.

Ivanov had gone to the bedroom and laid his attaché case on the bed. Set his mobile phone on the edge of the bed. Opened the attaché case, so intent on the contents that he did not notice having knocked the phone onto the carpet or kicked it under the bed, for Victor to find later. What did Ivanov slip from the shoe sack: a brick, a gun, a bar of gold? Arkady walked through every move, trying to align himself on an invisible track. Pasha had opened the walk-in closet and found the floor covered in salt. Did he know about a coming worldwide shortage of salt? Good men were the salt of the earth. Smart men salted away money. Pasha had rushed home to eat salt, and all he took with him on his ten-story exit was a shaker of salt. Arkady inverted the shoe sack. No salt.

This thing from the sack, was it still in the apartment? Ivanov had not taken it with him. As Arkady remembered, everyone focused on company matters, and a shoe sack was the wrong size and shape for either computer disks or a spreadsheet.

The phone rang again.

Ozhogin said, "Renko, don't hang-"

Arkady hung up and left the receiver off the hook. The colonel's problem was that he had no leverage. Had Arkady been a man with a promising career, threats might have worked. But since he was dismissed from the prosecutor's office, he felt liberated.
