Bingo, Carmaggio said softly, and spat the gum in his mouth toward a manhole cover.

The back courtyard was cold and slick with the last rain; which kept the smell down, at least. He walked over to the body.Damn, that's unusual. You got used to corpses in all sorts of positions; upside down, hanging from things, in beds, in cars. Once he'd had a killing where the girlfriend's body got stuffed into a large sealed crate andmailed by the ex-wife to the husband. Who'd fainted, fallen over backward, and killed himself when he opened the crate-and that presented some interesting evidentiary problems.

This one was lying on his stomach, with the forward third of his body propped up against the brick wall of the building. As if he'd run right into it and poured down, like Wile E. Coyote in one of the old Road Runner cartoons.

Carmaggio took his hands out of his pockets and pulled on a pair of gloves. Another fun night in the Busiest Precinct in the World, he said. A couple of the uniforms and technical people laughed as they went about their business.

They were about a block from Times Square; he could see the reflected lights of the Embassy in a puddle out on the street, beyond the cars and the cordon. At least now the press had had a month to forget the warehouse killings, so he didn't have a flock of black-winged cameramen following him around, flapping and squawking and waiting for something to die. There was a Sbarro's next to the Embassy, which reminded him he hadn't eaten.I'll get a meatball sandwich afterward, he decided.

Ai, me muero,Jesus Rodriguez said, gloving up as well. You know, there was a time when I thought I'd be catching murderers, not spending my days with the bodies.

Hmmm.

Carmaggio crouched behind the body for a second. Hands were down, resting on the ground palms up.

There was a smear of blood on the wet brick, starting about face height for someone the victim's height.

He touched a gloved finger to it and rubbed the result with the ball of his thumb; unscientific, he supposed, but it often worked as a rough-and-ready timecheck. Hard to tell, though, with this temperature and all the water oozing out of the brick-God damn all midwinter thaws, anyway, they screwed things up worse than snow. Maybe there was something to this global warming thing; winters had frozen harder when he was a kid.

The initial blood spatter was huge, like an inkblot in one of those old psychologist's tests. More blood in a pool around the base of the wall. Head injuries bled out fast, as bad as a major wound to the chest cavity.

What do I see in this? he wondered, stepping back and looking at the blot. I see someone who had their head shot out of a cannon at a wall, is what I see.

There was nothing around the body but garbage. He crouched again and used a pencil in his left hand to move the ponytail of greasy black hair that covered the victim's neck.Aha.

Livid bruises on either side of the spinal column, right above the shoulders. Look at this, he said.

Jesus joined him. Henry spread his hand as if he were about to take the back of the dead man's neck in it, a straightforward grab with the thumb on the left side. It fit exactly, thumb-mark and four fingers, although from the spacing the hand had been slightly smaller than Carmaggio's.

What does that say to you? he asked his partner.

Perp is right-handed, Jesus said helpfully.

Oh, funny man.

Geraldo has nothing to me,patron. I'd say someone put his face to that brick with an extreme quickness.

Henry grunted. How long?

Jesus picked up one of the hands by a thumb. There was a purplish sheen to the waxy skin, and a whitish spot appeared when the younger policeman stuck a finger in the livid patch that had lain nearest the ground. The joints of the hand moved freely.

Hour, maybe two, no more than three.

Right.

There was a bulletin out with the extremely incomplete description they'd gotten from the restaurant where Fischer had been seen last, but the chances of it doing any good were . . .Somewhere between nada, zip, and fucking zero, he thought resignedly. You couldn't pull in every tall redheaded woman within a mile of Times Square.

All right, let's move him.

Two of the uniforms came forward, and Jesus got out his minicam, speaking softly into the throat mike.

Henry whistled.

Teeth dropped out of the shattered mouth as the slack body was lifted free of the bricks. One of the patrol officers swallowed and wobbled a bit, until her partner hissed sharply at her. Broken jaw, mandible pushed right back. All the upper teeth snapped off. Frontal bones pushed in until there was nothing but a glistening mass of pulp, and the forehead had a dished look.

Carmaggio felt a little off himself.Nothing I could take to court, but it's the same MO, he thought. The skin along the nape of his neck roughened.Angel dust? he mused.

Somethingunnatural was behind this combination of speed and strength and utter savagery.

Right, let's see if this is who I think it is, he said. He slid a hand inside the dead man's jacket and began checking pockets. Green cards, blank. Social Security, ditto. Oho, Jojo was getting upscale-passport.

Couple of computer disks. Official stationery . . .

Jojo? Jesus said.

Do-it-while-you-wait Jojo Jackson himself, Carmaggio confirmed. Aha.

A piece. A .32 revolver in a waist holster, no sights, trigger guard cut away-Jojo had always liked to think of himself as seriously bad; in fact, he'd just been bad. Not a very good documents man, either.

Sooner or later something like this was going to happen to him-the means might have been more conventional, but the result was much the same.

There was something a little farther down the alley, too. A scrap of paper flecked with blood and plastered to the wet side of a dumpster. A C-note.

Somebody might want to bag this, he said mildly. More of the warehouse money.

Now, why do you come to Jojo? Jesus said, imitating Carmaggio's voice.

ID.Lots of things you could do with cash, but you needed some ID for most of them. Like moving around, buying airplane tickets, renting a car. Not necessarily very good ID-people just didn'tlook most of the time-but some sort or paper.

Travel plans, he answered. Wherever the mystery killer was going, it was probably bad news for the recipients . . . but New York could use the breathing space.

Gwen unfastened her seatbelt and stood. Air flowed in through the door of the airliner, mildly warm.

Welcome to Cali, Colombia. Welcome to a country that had never even existed in her history; there had been a Republic of Grand Colombia from the 1820s, but that had stretched over all the Andean lands.

The smell of burnt kerosene was overwhelming, and she breathed through her mouth to compensate.

Outside only the distant mountains were familiar. Friends of hers had estates here, growing coffee and stock and heaven-berries and ganja-in the Domination's timeline. There was a minor liftport and a settlement nearby, mostlyservus. This millions-strong monstrosity was almost completely alien, save for a few ancient Spanish churches and public buildings preserved for aesthetics in both histories.

She hefted her bags and followed the crowd to the Customs checkthroughs. Green-uniformed guards with submachine guns slung across their chests waited among the milling crowd. Some of them had guard dogs on leashes. The animals' heads came up as they scented her, tracking back and forth with cocked ears to find where the unfamiliar trace came from. One of them began barking and tugging at his lead, until the policeman quelled him with a sharp order. Passengers surged away from the growling and bared teeth.

Noisy lot, humans,she thought.

Their smell lay heavy in the concourse. It had none of the sharp clean scent of her own species, or the comforting sweetness ofservus; the harsh feral smell put her teeth on edge. She showed them in a snarl of her own for an instant. It was a good thing that humans couldn't use their noses for anything but keeping their eyes and upper lips apart; if they had a decent sense of smell she'd never have been able to hide. And what theydid scent, they only noticed subliminally, most of the time. She had been working on her pheromones during the flight. It took a while to adjust them upward, although toward the end the cabin staff and several passengers had been hovering around her seat-without knowing exactly why, of course. She smiled as she handed her forged passport to the clerk.

He was only a pace away across the desk. His brown skin flushed as he looked up at her. She took off her sunglasses and tucked them into a pocket, smiling as she met his eyes. The Colombian swallowed and put a hand to the collar of his shirt.

Welcome to Colombia, he said mechanically.

Why, thank you, she said, smiling more widely. The forged passport rested between the fingers of her right hand. It looks like a lovely country.

Ah . . . your Spanish is excellent, he stammered. Several of the other clerks were looking at him oddly; he straightened and cleared his throat.

Thank you, Gwen said.

It wasn't difficult to learn, when you had an eidetic memory; just read a grammar and spend a few days listening to Spanish-language television, of which New York had plenty, and practice a little. She probably had a Puerto Rican accent.

Ah, purpose of visit?

Business, she said. To be precise, laundering $970,100 in American currency, but no need to go into details. Some contacts with the local criminal classes might also be useful.

How long do you expect to remain in Colombia?

About a month.

Drops of sweat were rolling down the clerk's face. The men at the other desks were glancing over again and again.Hmmm. Perhaps a little too much on the pheromones.

Your papers, please, and put the luggage here.

She put the suitcase on the flat surface and handed him the passport. He dropped it to the desk and opened it, reaching for his stamp.

That he hesitated only an instant when he saw the ten hundred-dollar bills folded inside the passport said a good deal for his nerves and self-control, especially when you remembered the effects of the pheromones. The standing desk had a wooden rim around it; the bills vanished into a drawer.

Thump.The stamp went down on her passport, and the clerk opened the suitcase and gave the clothes inside a cursory inspection. The money was underneath the folded garments, in neat bundles wrapped in plain paper and sealed with tape.

Enjoy your stay, Senora Smith, the clerk said. He hesitated, then went on: If you need assistance . . .

and slipped a piece of paper across the desk. With his name and address on it.

She palmed it. I'll certainly remember your kind offer, Senor Gaitan, she said.

The man looked after her as she walked away, until a supervisor came by and cleared his throat. She continued slowly, thinking. A hotel, of course. Then . . .

Gwen!

Why, hello, Dolores, Gwen said.

One of the flight attendants; Dolores Ospina Pastrana. They'd chatted on the plane, although of course she hadn't understood exactly why this particularyanqui was so interesting, so charismatic. The stewardess was pulling her luggage along on a wheeled carryall, looking trim and efficient in her blue uniform. She fidgeted with the handle, Do you have a ride?

Gwen smiled, white teeth flashing. Why, no, I don't. Thank you for the offer; I hope it isn't an inconvenience.

No, no, I'm off duty for the next three days.

That's wonderful, Gwen said, smiling more broadly. Her nostrils flared slightly. Perhaps you could show me some of the sights.

She didn't intend to stay in Colombia long, and a native guide would certainly help her get started more quickly. The evidence could always be disposed of, one way or another.

It's a lovely city, Dolores said. But it can be dangerous for an outsider.

Gwen chuckled. Let's go. I'm sure you can shield me from the perils of ignorance.

Whodid you say you were with? Mary Chen asked, stepping in front of the personable young man before he could pass through.

We're with the Federal government, Dr. Chen, he said, with a frank, open smile.

He was wearing a nondescript dark suit and raincoat; so was his friend. They were both six-footers, one young and dark, the other fortysomething, heavy, and graying blond; the older man looked like an athlete gone very slightly to seed, or a lawyer who spent a couple of nights a week at the gym. He carried something like an attache case, only considerably larger. Unlike his younger companion, he didn't smile.

Well, that's you and a couple of hundred thousand others, even under this administration, Chen said.

What does the Federal government want with medical evidence being held in an ongoing investigation?

Nobody waltzes intomyoffice like this! It might not be much of an office; cluttered, with a couple of spider plants on top of the filing cabinets, and smelling faintly of disinfectant from downstairs, but it was her turf.

The young man laughed easily, eyes crinkling. We're with an executive agency, he said. And it's not an ongoing investigation anymore. Since it's a closed file, I'm sure you won't object . . .

Great, an executive agency. FBI, CIA, NSA, Bureau of Indian Affairs, NASA, what?

He reached into his jacket. The City wants full cooperation, he said gently, and extended a handful of documents.

She read raising her brows. Impressive. It was; including two heavy hitters in the NYPD. Unfortunately, you don't seem to have noticed that I'm a medical examiner-and we're appointed by the courts. We're not part of the police department.

She handed the sheaf of paper back. Mary Chen had spent a good deal of the last twenty years around police officers; long enough to recognize the very slight bulge below the young man's left armpit. Icy certainty paralyzed her mind for an instant. Thesewere Feds of some sort; it would be deeply stupid to make a claim she could refute with a simple phone call. And they were serious. Some sort of Federal cop, or more likely spooks; FBI would have been more open about who they were.

The older one stepped by her and put his carrying case on the desk. He pressed the buttons on a digital lock and snapped the catches open with his thumbs, the metallicclick loud in the little room. Much of the space inside was insulation, leaving just enough for an arm. A very large arm.

Look, she began. If you think I'm going to sit still for this, you're very much mistaken.

The young man's smile didn't waver. He reached a black-gloved hand inside his jacket and produced another folded paper.

Dr. Chen, this is a national security matter, he said. She snorted.

If you'll take a moment to think about it, you'll realize that that's not just a phrase to shut you up. We're nearly into the twenty-first century, and pretty soon genetics are going to be as important to our security as electronics have been for the past few decades. Youmust realize something of how sensitive this matter is, or you wouldn't have kept it as quiet as you have-nothing to the press, no publicity, just a few friends of yours at the university, nothing on paper. That's fine, but this needs to be studied by top people. We can provide the facilities. You can't; with all due respect, you're a forensic pathologist, not a research geneticist. No offense.

None taken, she said between clenched teeth.

Before she could continue, the man handed over the letter.

The United States needs to keep its technological edge, he said earnestly. Otherwise, our influence goes; and it's an influence for good, well beyond our borders.

The paper was an official document, but not from the American government. The language was Vietnamese; in the upper right-hand corner was an identity photograph of her aunt Edelle. Who was still in Hue . . . in a Vietnam growing even more hostile to its ethnic-Chinese minority since the naval clashes over those damned islands. Not that it had ever been very friendly.

I didn't even know she was still alive, Chen whispered.
