Baby building is a complex operation, run with military precision. The chromosomes form command central, with squads of grunt genes taking orders from control genes, which answer to more control genes higher up the chain.

At first the embryo is an undifferentiated mass. An order is issued.

Vertebrate!

Segmented bones form around a spinal cord, jointed limbs with five digits each. A skull. A real jaw.

The embryo is a perch. A wood frog. A gecko.

The double-helix generals up the ante.

Mammal!

Homeothermy, viviparity, heterodonty.

The embryo is a platypus. A kangaroo. A snow leopard. Elvis.

The generals push harder.

Primate!

Opposable thumbs — 3-D vision.

Harder.

Homo sapiens!

Gray matter to die for. Bipedality.

The human skeleton begins to ossify around the seventh week. Between the ninth and twelfth, tiny tooth buds appear.

I identified four cranial elements in the crime scene photos.

The sphenoid is a butterfly-shaped bone that contributes to the orbits and to the cranial base. The large wings arise during the eighth fetal week, the small pair follows a week later.

Using the scope and a calibrating grid, I measured length and breadth. Using the ABFO ruler for scale, I calculated actual size. Greater wing: fifteen by seven millimeters. Lesser wing: six by five millimeters.

The temporal bone also comes with some assembly required. The flat portion forming the temple and the most lateral part of the cheekbone appears during the eighth fetal week. This one measured ten by eighteen millimeters.

The tympanic ring begins life at approximately week nine, grows to three bony slivers during the next twenty-one days. The slivers join to form a ring around week sixteen. Just before baby checks out of the uterine hotel, the ring attaches to the ear opening.

That first puzzling speck I'd seen in the pelvic photo was a tiny tympanic ring. Though lines of fusion were still evident, the three segments were firmly attached. The ABFO ruler indicated I was viewing the ring dead on. I measured diameter, corrected, added the figure to my list. Eight millimeters.

I turned my attention to the vial.

A miniature half jaw, with sockets that would never hold teeth. Twenty-five millimeters.

One collarbone. Twenty-one millimeters.

Moving through tables in the fetal osteology book, I checked each measurement. Sphenoid greater wing. Sphenoid lesser wing. Temporal squamous. Tympanic ring. Mandible. Clavicle.

According to Fazekas and Kósa, the girl in the tank had been five months pregnant.

I closed my eyes. The baby had been six to nine inches long and weighed around eight ounces when its mother was killed. It could blink, grasp, make sucking motions. It had eyelashes and fingerprints, could hear and recognize Mom's voice. If it was a girl, she had six million eggs in her tiny ovaries.

I was feeling overwhelmed by sadness when Elena called out from the doorway.

'There's a call for you.'

I didn't want to talk to anyone.

'A Detective Galiano. You can take it in Mateo's office.'

I thanked Elena, resealed the evidence in its vial, and climbed back to the second floor.

'Five months,' I said, skipping preliminaries.

He needed no explanation.

'About the time she might have been leveling with Papa.'

'Her own, or the donor of the lucky sperm?'

'Or nondonor.'

'Jealous boyfriend?' I threw out.

'Angry pimp?'

'Psycho stranger? The possibilities are endless. That's why the world needs detectives.'

'I did some detecting this morning.'

I waited.

'The Eduardos are the proud owners of two boxers and a cat. Lucy Gerardi's family has a cat and a schnauzer. The De la Aldas are not animal lovers. Nor are the ambassador and his clan.'

'Patricia Eduardo's boyfriend?'

'A ferret named Julio.'

'Claudia de la Alda's?'

'Allergies.'

'When will your trace guys be done viewing the samples?'

'Monday.'

'What did the DA have to say?'

I heard Galiano draw a long breath through his nostrils.

'His office will not be releasing the skeleton.'

'Can we have access at the morgue?'

'No.'

'Why not?'

'The guy really wanted to be my best friend, was devastated he couldn't discuss the case.'

'Is this typical?'

'I've never been stonewalled by a DA, but I've never tangled with this one.'

I pointed my thoughts at that for a while.

'What do you think is going on?'

'Either the guy's got a hard-on for protocol, or someone's putting the screws to him.'

'Who?'

Galiano didn't answer.

'The embassy?' I asked.

'What are you doing?' There was a dark guardedness to his voice.

'Now?'

'For the junior prom.'

I could see why Ryan and Galiano had hit it off.

I looked at my watch. Five-forty. A Saturday evening calm had settled over the lab.

'It's too late to start anything here. I'll head back to my hotel.'

'I'll pick you up in an hour.'

'For?'

'Caldos.'

I started to object, pictured the gathering of one I'd attend in my room.

What the hell.

'My dress is blue.'

'O.K.' Puzzled.

'I prefer a wrist corsage.'

===OO=OOO=OO===

'Donated by a citizen with a horticultural bent.' Galiano proffered two pansies stapled to a blue rubber band.

'Donated?'

'The band is sold separately.'

'Broccoli?'

'Asparagus.'

'They're lovely.'

Cars honked and jockeyed as we walked toward the Cafe Gucumatz. An early evening shower had come and gone, and the air smelled of wet cement, diesel fuel, earth, and flowers. Now and then the soggy maize scent of tamal or chuchito drifted by as we passed a vendor's cart.

We shared the sidewalk with throngs of others. Couples heading out for dinner or drinks. Young professionals returning home from work. Shoppers. Saturday-evening strollers. A breeze tossed ties over shoulders and molded skirts to legs and hips. Overhead, palm fronds rose and fell with soft clicking sounds.

The Gucumatz was done in techno-Mayan, with dark wooden beams, plastic flora, and an artificial pond with arching bridge. Murals decorated every wall, most depicting the fifteenth-century Quiche king who'd lent his name to the place. I wondered how Feathered Serpent felt about the implied endorsement, but kept it to myself.

Lighting was by torch and candle, and entering was like passing into a Mayan tomb. As my pupils dilated, a parrot shrilled greetings in Spanish and English. So did a man in white shirt, black pants, and apron.

'Hola, Detective Galiano. Hello. ¿Cómo está?'

'Muy bien, Señor Velasquez.'

'Such a long time since we've seen you.'

An enormous mustache handle-barred over Velasquez's mouth, plunged south at the sides, then curled back north as though reaching for his nostrils. I thought of an emperor tamarin.

'Working my tail off, Señor.'

Velasquez wagged his head in understanding.

'Crime is so terrible today. Everywhere. Everywhere. The citizens of this city are privileged to have you on the job.'

Another sad head shake, then Velasquez took my hand and pressed it to his lips. The facial hair felt like steel wool.

'Bienvenido, señorita. A friend of Detective Galiano is always a friend of Velasquez.'

Releasing my fingers, he flashed both eyebrows at Galiano and winked theatrically.

'Por favor. My best table. Come. Come.'

Velasquez led us to his prize pond-side seating, turned and beamed at Galiano. The detective tipped his head toward the restaurant's interior.

'Si, Señor. Of course.'

Velasquez hurried us to an alcove constructed around a back corner, and gave Galiano a questioning look. My companion nodded. We entered the cave and sat. Another Groucho display for the great crime fighter, and our host withdrew.

'That was as subtle as a baboon's ass,' I said.

'I apologize for the machismo of my brothers.'

Within seconds a waitress appeared with menus.

'Libation?' Galiano asked me.

Oh, yeah.

'Can't do it.'

'Oh?'

'Over quota.'

Galiano did not question that.

He ordered a Grey Goose martini neat. I asked for Perrier with lime.

When the drinks arrived, we opened our menus. The lighting had gone from low to nonexistent with our relocation to the underworld, and I could hardly make out the handwritten text. I wondered about Galiano's motive for the move, but didn't ask.

'If you haven't had caldos, I recommend it.'

'Caldos being…?'

'Traditional Mayan stew. Tonight they have duck, beef, and chicken.'

'Chicken.' I closed my menu. I couldn't read it anyway.

Galiano chose beef.

The waitress brought tortillas. Galiano took one, offered the basket.

'Gracias,' I said.

'When?' He settled back into his chair.

I'd missed a bridge somewhere.

'When?' I repeated his question.

'When did you burn your allotment?'

I made the connection, but had no intention of discussing my love affair with alcohol.

'A few years back.'

'Friend of Bill Wilson?'

'I'm not a joiner.'

'A lot of people rely on AA.'

'It's a wonderful program.' I reached for my glass. The bubbles made soft fizzing sounds as the ice settled. 'Was there something you wanted to tell me about the case?'

'Yes.'

He smiled, sipped his martini.

'You have a daughter, correct?'

'Yes.'

Pause.

'I have a son. He's seventeen.'

I said nothing.

'Alejandro, but he prefers Al.'

Galiano continued, unconcerned by the lack of feedback.

'Bright kid. He'll start college next year. Probably ship him up to Canada.'

'St-F.X.?' I hoped to blow a hole in his unassailable self-confidence.

Galiano grinned.

'That's where you scored the Bat tidbit.'

So he had caught my use of his nickname at headquarters.

'Who?' he asked.

'Andrew Ryan.'

'Ay, Dios.'

He threw back his head and laughed.

'What the hell's Ryan up to these days?'

'He's a detective with the provincial police.'

'Using his Spanish?'

'Ryan speaks Spanish?'

Galiano nodded. 'We used to discuss passing members of the opposite sex and no one knew what we were saying.'

'Commenting on their intelligence, no doubt.'

'Sewing skills.'

I drilled him with a look.

'It was a different time.' The waitress arrived, and we both set to seasoning stew. Then we ate in silence, Galiano's eyes roving the restaurant. Had someone been watching, they'd have thought us a couple grown bored with each other. Finally, 'How well do you understand the Guatemalan justice system?'

'Obviously, I'm an outsider.'

'You know you're not working in Kansas here.'

Jesus. This guy was just like Ryan.

'I know about the torture and assassination, Detective Galiano. That's why I'm in Guatemala.'

Galiano took a bite of stew, pointed his fork at mine.

'It's better hot.'

I resumed eating, waited for him to go on. He didn't. Across from our catacomb, an old woman cooked tortillas on a comal. I watched her toss dough, lay it on the flat clay pan, and place it over the fire. Over and over her hands moved through the motions, her face a wooden mask.

'Tell me how the system works.' It came out sharper than I intended, but Galiano's evasiveness was starting to irritate.

'We don't have jury trials in Guatemala. Criminal matters are investigated by judges of the first instance, primera instancia, occasionally by magistrates appointed by the Supreme Court. These judges, you'd call them DAs, are supposed to seek both exculpatory and incriminating evidence.'

'Meaning they act as both defense and prosecution.'

'Exactly. Once the investigating judge decides that there's a case against an accused, he passes the matter on to a sentencing judge.'

'Who has the power to order an autopsy?' I asked.

'The judge of the first instance. An autopsy is mandatory in a violent or suspicious death. But if cause can be determined by external exam, there's no Y incision.'

'Who's in charge of the morgues?'

'They're directly under the authority of the president of the Supreme Court.'

'So forensic doctors really work for the courts.'

'Or for the national social security institute, the Instituto Guatemalteco de Seguridad Social, IGSS. But yes, forensic doctors are under the authority of the judiciary. It's not like Brazil, for example, where the state-run medico-legal institutes work for the police. Here forensic doctors have very little interaction with the police.'

'How many are there?'

'Around thirty. Seven or eight work at the judicial morgue here in G City, the rest are spread out across the country.'

'Are they well trained?'

He ticked points off on his fingers. It took only three.

'You must be a Guatemalan citizen by birth, a medical doctor, and a member of the medico-legal association.'

'That's it?'

'That's it. Hell, USAC doesn't even have a residency program in forensic medicine.'

He referred to the University of San Carlos, Guatemala's only public university.

'Frankly, I don't know why anyone does it. The status is zip and the pay sucks. Have you been to the G City morgue?'

I shook my head.

'It's like something out of the dark ages.'

He used a torn tortilla to sponge sauce, then pushed his bowl aside.

'Are forensic doctors full-time employees?'

'Some are. Some work for the courts just to supplement their earnings. Especially in rural areas.'

Galiano's eyes darted left as the waitress entered. She cleared dishes, asked about dessert and coffee, left.

'What's the drill when a body is found?'

'You'll love this. Until about ten years ago, stiffs were collected by the fire department. They'd arrive on scene, examine the body, take pics, then call it in. Central dispatch would notify the police, and we'd notify the judge. Police investigators would then gather evidence and take statements. Eventually the judge would show up, release the body, and the firemen would take it to the morgue. Today police vehicles are used for transport.'

'Why the policy change?'

'Fireman Friendly and his colleagues were helping themselves to money and jewelry.'

'So forensic doctors don't usually go to the scene?'

'No.'

'Why Lucas?'

'Diaz probably gave him no choice.'

The coffee arrived, and we sipped in silence for a few moments. When I looked out at the old woman, Galiano's eyes followed mine.

'Here's something else you'll find appalling. In Guatemala, forensic doctors are only required to determine cause, not manner.'

Galiano referred to the four terms used to categorize the circumstances of death: homicide, suicide, accident, natural. A body is found in a lake, and an autopsy determines that sufficient water filled the lungs to have halted breathing. Cause of death is drowning. But did the deceased fall, jump, or was he pushed? Those are issues of manner.

'Who determines manner?'

'The judge. DA.'

Galiano observed a couple being seated on the far side of the room. Then he turned his chair slightly, leaned in, and lowered his voice.

'Are you aware that many of those who were involved in atrocities remain in command of the military?'

He spoke in a voice that sent goose bumps crawling up my arms.

'Do you know that many of those performing investigative work today were or are direct participants in extrajudicial executions?'

'Are?'

His eyes held steady on mine.

'The police?'

Not a flicker.

'How can that be?'

'Although nominally under the jurisdiction of the Interior Ministry, the police here remain effectively under army control. The criminal justice system is permeated by fear.'

'Who's afraid?'

Another visual sweep. Not a movement was going unnoticed. When Galiano turned back to me his face was a harder version of the one it had been.

'Everyone's afraid. Witnesses and relatives won't swear out complaints, won't testify for fear of retribution. When evidence leads to the army, a prosecutor or judge has to worry about what will happen to his family.'

'Aren't monitors watching out for human rights violations?' My voice was barely above a whisper. Galiano was getting to me.

He blew air through his lips, glanced over my shoulder.

'More monitors have been killed or disappeared in Guatemala than anywhere else on the planet. That's not my stat, it's official.'

I'd read that in a recent Human Rights Watch.

'And we're not talking ancient history. All but four of those murders have taken place since the civilian government was established in eighty-six.'

I felt a tingle of fear in the pit of my stomach.

'What is your point?'

'Death investigation here ain't day care work.' His eyes were dark with bitterness. 'Produce an autopsy finding or a police report that implicates the wrong people, life's no longer clean and easy. Reporting results can be hazardous if the recipient of your report happens to be affiliated with the bad guys even though he's holding a prosecutorial office.'

'Meaning?'

He started to say something, then his eyes backed away.

The tingle coalesced into a cold, hard knot.
