A tour bus blocked the route across the avenue. It was a double decker with smoke rolling from its underbelly and rows of woeful heads poking from the top tier, unstirring Swedes and Chinese, their fanny packs stuffed with currency.

Michael Chin was still in the jump seat, facing rearward. He'd listened to the audio account of the assassination but had not turned to look at the screens.

Eric watched him now, wondering whether the young man's restraint was a form of moral rigor or an apathy so deep it was not pierced by the muses, even, of sex and death.

"While you were away," Chin said. "Yes. Tell me."

"There was a report that consumer spending is weakening in Japan." He spoke in a newscaster's voice. "Raising doubts about the country's economic strength."

"See. What. I said as much."

"The yen is expected to fade. The yen will sink a bit."

"There we are. See. Has to happen. The situation has to change. The yen can't go any higher."

Torval came walking back to this end of the car. Eric lowered the window. Windows still had to be lowered.

Torval said, "A word."

"Yes."

"The complex recommends extra security."

"You're not happy about this."

"First a threat to the president."

"You're confident you can handle whatever comes up."

"Now this attack on the managing director."

"Accept their recommendation."

He raised the window. How did he feel about additional security? He felt refreshed. The death of Arthur Rapp was refreshing. The prospective dip in the yen was invigorating.

He scanned the visual display units. They were deployed at graded distances from the rear seat, flat plasma screens of assorted sizes, some in a cluster framework, a few others projected singly from side cabinets. The grouping was a work of video sculpture, handsome and airy, with protean potential, each unit designed to swing out, fold up or operate independent of the others.

He liked the volume low or the sound turned off.

They were climbing down out of the tour bus now. It seemed to be sinking into the dark smoke that foamed up around it. A derelict tried to board, dressed in bubble wrap. There were sirens in the distance, fire trucks caught in traffic, the sound hanging in the air, undopplered, and car horns blowing locally, another hardness upon the day.

He felt his elation deepen. He slid open the sunroof and thrust his head into the reeling scene. The bank towers loomed just beyond the avenue. They were covert structures for all their size, hard to see, so common and monotonic, tall, sheer, abstract, with standard setbacks, and block-long, and interchangeable, and he had to concentrate to see them.

They looked empty from here. He liked that idea. They were made to be the last tall things, made empty, designed to hasten the future. They were the end of the outside world. They weren't here, exactly. They were in the future, a time beyond geography and touchable money and the people who stack and count it.

He sat down and looked at Chin, who was biting the dead skin at the side of his thumbnail. He watched him gnaw. This was not another of Michael's tender reveries. He was gnawing, grinding his teeth on the hangnail, then the nail itself, the base of the nail, the pale arc of quarter moon, the lunula, and there was something awful and atavistic in the scene, Chin unborn, curled in a membranous sac, a scary little geek-headed humanoid, sucking his scalloped hands.

Why is a hangnail called a hangnail? It's an alteration of agnail, which is Middle English, Eric happened to know, from Old English, with roots in torment and pain.

Chin loosed one of his vegetarian farts. Mode control ate it at once. Then there was an opening and the car bucked and lurched, veering in a screech around the tour bus and across the avenue. The man at the taco cart solemnly watched. The car wobbled over the curbstone and sphinctered free and Chin's eyes came out of lunar seclusion when it raced all the way to Park along a surreal length of empty street.

"Time for you to do what."

"Yes. All right," Chin said.

"You don't know this? We both know this."

"There's work to do at the office. Yes. I need to retrace events over time and see what I can find that applies."

"Nothing applies. But it's there. It charts. You'll see it." "I need to back-test currencies, I don't know, like into the misty dawn."

"We can't wait for the misty dawn."

"Then I'll do it here. To save time. That should make you happy. I do time cycles in my sleep. Years, months, weeks. All the subtle patterns I've found. All the mathematics I've brought to time cycles and price histories. Then you start finding hourly cycles. Then stinking minutes. Then down to seconds."

"You see this in fruit flies and heart attacks. Common forces at work."

"I'm so obsolete I don't have to chew my food."

"You can't stay here."

"I like it here."

"No, you don't."

"I like riding backwards." Chin spoke in his newscaster voice. "He died as he lived. Backwards. Details after the game.

He felt good. He felt stronger than he had in days, or weeks maybe, or longer. The light was red. He saw Jane Melman on the other side of the avenue, his chief of finance, dressed in jogging shorts and a tank top, moving in a wolverine lope. She stopped at the prearranged pickup spot, next to the bronze statue of a man hailing a cab. Then she looked in Eric's direction, squinting, trying to determine whether the limousine was his or someone else's. He knew what she would say to him, first line, word for word, and he looked forward to hearing it. He could hear it already in the nasal airstream of her vernacular. He liked knowing what was coming. It confirmed the presence of some hereditary script available to those who could decode it.

Chin hopped out the door before the car crossed Park Avenue. There was a woman in gray spandex on the median strip holding a dead rat aloft. A performance piece, it seemed. The light went green and horns began to blow. On buildings everywhere in the area the names of financial institutions were engraved on bronze markers, carved in marble, etched in gold leaf on beveled glass.

Melman was running in place. When the car stopped at the corner, she left the shadow of the glass tower behind her and came bumping through the rear door, all elbows and gleaming knees, a web phone pouched on her belly. She was breathless and sweaty from her run and fell into the jump seat with the kind of grim deliverance that marks a deadweight drop to the toilet.

"All these limos, my god, that you can't tell one from another."

He narrowed his eyes and nodded.

"We could be kids on prom night," she said, "or some dumb wedding wherever. What's the charm of identical?"

He glanced out the window, speaking softly, so cool to the subject that he had to deliver his remark to the steel and glass out there, the indifferent street.

"That I'm a powerful person who chooses not to demarcate his territory with singular driblets of piss is what? Is something I need to apologize for?"

"I want to go home and tongue-kiss my Maxima."

The car was not moving, There was a noise beating down that made people cover up when they walked past, rumbling gutturals from the granite tower being raised on the south side of the street, named for a huge investment firm.

"You know what today is, incidentally."

"I know"

"It's my day off, damn it."

"I know this."

"I need this extra day desperately."

"I know this."

"You don't know this. You can't know what it's like. I am a single struggling mother."

"We have a situation here."

"I am a mother running in the park when my phone explodes in my navel. I think it's the kids' nanny, who never calls until the fever reaches a hundred and five. But it's the situation. We have a situation all right. We have a yen carry that could crush us in hours."
