"How did Alexandra die?"

Cristina backed away from me. "In a painful, hard way that I prefer not to discuss."

"Did she have a boyfriend, a girlfriend, anyone I could talk to?"

"What are you trying to ask?" Cristina hissed.

So she knew her daughter had women as lovers. Alexandra wouldn't come out of the closet for fear her mother would learn, and her mother had known all along. Had Alexandra committed suicide because of the pressure? Had Nadia known and moved out after fighting with her mother over Allie's s.e.xuality?

I couldn't think of any good way to ask these questions, so I asked in a bad way. "Who told you that Alexandra was sleeping with women?"

Cristina gasped. "If you came here to slander my saint, my angel, I will call the police. Leave!"

"I'm not trying to upset you, Ms. Guaman, just to figure out who killed your beloved daughter Nadia."

"They arrested a man. It's enough, enough that we're dragged through the dirt by Nadia, without you coming to me and pouring it over me."

"I went to Nadia's apartment this morning," I said. "Someone had broken in, had stolen her computer and all her discs. All her artwork is missing."

At that, she became very quiet. She shook her head slowly as if unhappy at whatever she was thinking, but even though I tried several different gambits, she wouldn't share her private thoughts with me. I told her about Nadia's conviction that someone was spying on her.

"Who would that have been, do you think?" I asked. "The person who murdered her?"

Cristina shook her head again. "Nadia had many unhappy ideas, and not very many of them are-were-true. Was it she who told you those filthy lies about Alexandra? Nadia believed them and wouldn't accept my word that her sister was pure, a good Christian, not capable of such acts. But enough anger. Nadia is with her sister now, in the arms of the Blessed Mother. I thank G.o.d that she has no more pain on this earth."

That was all I was going to learn from her: Nada about Nadia. I walked unhappily from the store, wondering just what it was Cristina Guaman didn't want me to know about her daughter. Daughters.

I stopped in a taqueria across the street for a bowl of rice and beans. Ernie couldn't tell me anything. Even if I could get past security at O'Hare to reach Lazar Guaman, it was hard to convince myself that such a gray and beaten man would talk to me. That left the surviving daughter, poor young Clara. It was two-thirty-with luck, I'd make it to her school before she left.

17.

Vow of Silence.

I rode the Green Line to Halsted and walked the few blocks to St. Teresa of Avila Prep. School got out at three, and the city buses were already lined up. Unless the Guamans' self-appointed protector could leave his La Salle Street practice to collect Clara, the easiest route home for her was on the Number 60 bus down Blue Island Avenue. rode the Green Line to Halsted and walked the few blocks to St. Teresa of Avila Prep. School got out at three, and the city buses were already lined up. Unless the Guamans' self-appointed protector could leave his La Salle Street practice to collect Clara, the easiest route home for her was on the Number 60 bus down Blue Island Avenue.

I reached the school about ten minutes ahead of the exodus. I shivered in the bus stop catty-corner to the school until the tall doors opened and the students poured out.

They seemed to arrive in one giant wave of screaming, jostling teens, but as they pa.s.sed me they broke into little clots-groups of high-spirited boys, or girls laughing and kidding together, or couples in that adolescent embrace that doesn't allow a single molecule of air between their bodies. A number were walking alone, shoulders hunched to avoid the glances of a pitying world. Most were bent under their giant backpacks, looking much as their peasant forebears must have, lugging cotton or corn or wood. And all, it seemed, were madly reconnecting to their cell phones and music players after a day of forced withdrawal.

My dressy boots were elegant, but they weren't very warm. I was beginning to think I'd have to amputate my toes if I stood outside much longer, when Clara Guaman appeared in the middle of a knot of other girls. Unlike yesterday, when she'd gone bare-armed to her sister's funeral, she was dressed sensibly in a parka, although she hadn't bothered to zip it shut. She also had foresworn the gaudy eye shadow she'd sported at the funeral. When she and her friends had boarded their bus, I followed them and swiped my CTA card through the machine.

The driver, a thickset woman in her forties, nodded at the kids as they climbed up the steps. She looked at me in surprise-adults don't usually ride the school routes-but she didn't say anything. When the bus was packed from stem to stern, she rolled away from the curb. The shrieks and shouts of sixty or so kids, moaning over tests, over boyfriends or girlfriends, hotly arguing who'd said what to whom, made my head drum, but the driver just smiled to herself, focusing on the potholes that littered Blue Island Avenue. Like the rest of the world, she had her own little soundstage plugged into her ears.

I worked my way to the back, where Clara and her friends had found seats. She was talking animatedly, but her skin was gray, and there were dark circles under her eyes.

"V. I. Warshawski," I said when she looked up at me. "We met yesterday at your sister's funeral."

Her face shut down into the arrogant angry lines I'd seen at the church.

"Are you here to apologize some more? Don't bother."

"I want to know when I can talk to you-"

"You're doing it right now. I guess I can't make you shut up."

Her friends stared at us with frank curiosity.

"Privately."

"You can't. If there's something you want to say to me, do it right here. And then get out of my life."

We had both been bellowing to be heard over the ruckus around us, but the noise began dying down as kids nearby caught what we were saying. One of them asked if Clara wanted him to call 911.

"She's harmless," Clara said roughly.

I didn't want to say too much in front of this texting, Tweeting audience, but I needed some way of getting her to talk to me.

"When I heard the shots, I ran to your sister's side. I held her as she died. Her last word was a call to Allie."

The silence around us became absolute. Clara sucked in a breath, her face as shocked as if I'd slapped her. Her friends gazed at her with vampire-like avidity.

When Clara didn't say anything, I said, "Could we go someplace to talk about Nadia and your other sister?"

"You can't talk about Allie!" Clara cried.

"Why not?"

She looked around wildly, and then said, "Her name is sacred! You can't use it. No one is allowed to talk about her!"

The kids around us began murmuring excitedly among themselves. Even if I hadn't been tired and cold, the chatter made it hard to think. It certainly made the bus a stupid place to try to talk, but I plowed ahead.

"When did you last talk to Nadia?"

"I don't remember, and it's none of your business, anyway."

The lurching of the bus meant I couldn't keep my eyes on her face, but I thought Clara looked more scared than angry despite her defiant words.

"Your mother says she called Nadia when your sister was seen on YouTube painting on the Body Artist. How did Nadia respond?"

"Have you been talking to my mother? She has enough to worry about without someone like you b.u.t.ting in."

"Karen Buckley put on a special program in your sister's honor last night. Karen's the Body Artist who came to your sister's funeral."

"I remember who came to my own sister's funeral."

"What did Nadia tell you about Alexandra's death?"

At that question, Clara definitely looked more frightened than angry.

"I told you we can't talk about Allie, so b.u.t.t out!"

"All right, if we can't talk about Allie, let's talk about the Body Artist. How did Nadia find her?"

Clara looked at me but didn't speak. One of the boys near her left the bus. I took his place.

"The club was full last night for the Artist's program in your sister's memory. Rainier Cowles brought a party; one of the men-"

Clara bounced to her feet and bent to stick her head in my face. "If you're a pal of Rainier's, you can leave me alone. Go back to Prince Rainier and suck his d.i.c.k."

The raw language was meant to shock. She stared at me for a few seconds, hoping for some sign that she'd hit home. When I only smiled sadly because her youth and pain were so poignant, she marched to the front of the bus, deliberately shoving people, as if vicariously punching me.

Her friends gave me the kind of frigid looks I remembered from my own adolescence. They sniffed as if smelling garbage and pointedly turned away from me, then started giggling loudly.

"It would be more to the point if you'd help Clara," I said. "She's frightened and lonely."

This made them laugh more loudly.

The bus was stopped for the light at Nineteenth Street. I pulled out one of my business cards and scribbled on the back, "Rainier Cowles is not a friend or business a.s.sociate of mine, and I would never repeat anything you told me. Call or text me when you feel up to talking."

Enough kids had left the bus that it was easy for me to walk to the front and stand next to Clara. Her rigid posture, despite the weight of her backpack, told me she was very aware of my presence. I tucked the card into her parka pocket, but she refused to turn her head. I got off at the next stop and crossed the street to pick up a northbound bus.

As the winter twilight closed in on me, I rode buses and trains back to my office. My leasemate Tessa was hard at work, her half of the building flooded with spotlights and the flame of her blowtorch.

My own half was dark. I didn't bother turning on a light, just took off my boots and sat with my feet curled up under me on the sofa to warm them, trying to decode Clara Guaman's response to my questions.

Allie's name is sacred.

Clara had been told never to discuss her sister. But why? Because the family was afraid Alexandra's s.e.xuality would leak out? It was hard to accept that a parent still thought of h.o.m.os.e.xuality as so shameful, but of course many people do.

Clara thought, or feared, I was connected to Rainier Cowles. Last night at Club Gouge, he had claimed he was there to make sure the club respected Nadia, but he and his friends had definitely felt they were on a boys' night out and not at a wake.

Nor did I place any credence in Cowles's casting himself as an honorary uncle; lawyers like him bill themselves at five hundred dollars an hour or more. They don't waste their time on the families of baggage handlers. But if he wasn't protecting the Guamans, what was he doing hanging around their lives? He was certainly protecting something, and that something had to be himself, or possibly a high-flying client.

Allie, Nadia had cried. She wanted her sister, not her mother, as she was dying. Or she knew she was dying and hoped Alexandra would be there to greet her in the country of the dead. Nadia had cried. She wanted her sister, not her mother, as she was dying. Or she knew she was dying and hoped Alexandra would be there to greet her in the country of the dead.

At length, I turned on a light and walked over to my computer.

"Find me Alexandra Guaman. Fetch, boy!"

The floor was numbingly cold underneath my panty hose. I rummaged in my back storeroom and found an old pair of running shoes to wear as slippers.

While LifeStory was searching out Alexandra Guaman's details, I logged on to [http://embodiedart.com] embodiedart.com, the Body Artist's website. I wanted to look again at the paintings Nadia Guaman had made on the Artist to see if I could understand why they had roused Chad Vishneski so thoroughly.

Instead of the slide show I'd found on my previous visit to the site, the screen was blank except for the message "Out of respect for the dead, we have temporarily taken the site off-line." I somehow had not expected so much sensitivity on Karen Buckley's part. It forced me to think of her as less completely self-centered than she'd seemed.

I made myself a coffee and opened the report I'd ordered on Olympia, which had been sitting in my computer's pending folder since the previous afternoon. The details of Olympia's life were sketchy, as were her financials. She owned a loft apartment on the near North Side, in the stretch made newly hot by the destruction of the old Cabrini Green high-rises. She didn't actually own it; she was paying a mortgage on it, as she was on a summer place near Michigan City. The debt on the two properties was around half a million.

Olympia didn't own the building where she ran the club; that was held by a blind consortium managed through the Fort Dearborn Trust. I whistled through my teeth, trying to pick apart what I could of the club's finances.

Olympia had been running Club Gouge for almost three years. Her background had been in restaurants and entertainment; she'd managed a restaurant at one of the metro-area casinos, then opened a nightclub of her own in west suburban Aurora. The Aurora Borealis proved so successful that she'd apparently decided she was ready for the big city. Three years ago, she'd sold her Aurora place and opened Club Gouge.

Olympia's first two years at Club Gouge, even during the boom economy, had been disastrous. She'd run through almost a million dollars, maxed out her credit cards, and overdrawn her line of credit. And then, as the bottom fell out of the economy, just as everyone else in the country was losing their jobs and their homes, Olympia's bills were wiped clean. There was no way of seeing who her G.o.dfather had been, but someone had put a million dollars in cash into her account.

Santa Claus. Rodney Claus. He was the person Olympia was trying to keep happy. He was the one she'd called her "insecurity." But he wasn't Olympia's savior; he was the foot soldier sent to keep an eye on the investment.

Nadia had sought out the Body Artist because Buckley had known Allie. I couldn't get away from that. But how had Nadia found out that her sister had known the Artist? If murder happened because of the Guaman family's sensitivity over Allie's s.e.xuality, why was Nadia dead and not Karen Buckley?

I was making myself crazy with all these unprovable scenarios. It was close to five p.m. now. I'd planned on going home to walk the dogs and eat a bowl of pasta before meeting Murray, but I was too exhausted from my day in the snow. I called Mr. Contreras and asked him to let the dogs out. I was heading to the daybed in my back room, when my computer pinged to tell me one of my requested reports had arrived.

Alexandra Guaman. The file on her wasn't very big, but when I opened it the first thing I saw was her high school yearbook picture. Her face, framed by curly dark hair, didn't have a knife slash across the middle. Other than that, she looked like the portrait Nadia had drawn on the Body Artist's back. That didn't particularly startle me; I'd been expecting it. What jumped out at me was where she died. Alexandra Guaman had been working for a private security firm in Iraq. She'd been driving a truck on a supposedly safe route when an IED exploded and killed her.

18.

And the Wheel Goes Round and Round.

I printed out the files on Alexandra Guaman and took them with me into the back room to read while I stretched out on my daybed. An hour later when I came to, the pages were strewn across me and the floor like dead leaves. printed out the files on Alexandra Guaman and took them with me into the back room to read while I stretched out on my daybed. An hour later when I came to, the pages were strewn across me and the floor like dead leaves.

I struggled upright, washing the sleep out of my eyes under Tessa's shower, making myself coffee in our kitchenette. I had an hour before I had to meet Murray, and I was feeling so tense about my lack of headway that I wanted to get through as many doc.u.ments as I could.

What I had on Alexandra Guaman didn't tell me much. So many people have died in Iraq since we invaded that journalists now dump them all into a journalistic ma.s.s grave: fifteen killed in an explosion outside Basra, seven dead in a Baghdad market, thirty obliterated in a bombing run on Fallujah.

Alexandra's bio was correspondingly slim: the oldest of the Guaman daughters, the first to attend St. Teresa of Avila Prep, followed by college at DePaul here in Chicago, a degree in communications, then a job at Tintrey, the big security contractor. Tintrey's headquarters were in Chicago, or at least the suburbs, in the corporate corridor along the north leg of the Tri-State.

Alexandra had gone to Iraq for Tintrey four years ago. Tintrey had contracts for everything from over-the-road trucking to providing field first-aid kits. Alexandra's job t.i.tle, a level 8 employee in communications, could have meant anything: creating PR, monitoring computer networks, getting real-time information to field personnel.

Chicago's Latino paper had an obituary, showing the smiling yearbook picture I was getting to know by heart. I squinted at the page, picking my way through the Spanish: the anguish of the parents, the long wait for news, the sad realization when Alexandra's boss wrote a letter of condolence to the family: an IED had exploded when she was heroically driving a truck as part of a convoy to the Baghdad airport.

Nothing in the story, or in any of my skimpy reports, about her s.e.x life. Or about the Body Artist. Maybe Alexandra had been a lesbian, but she'd been in Iraq at the same time as Chad Vishneski. It was her face on the Body Artist that roused him to fury.

Had she turned Chad down in Baghdad? Had an affair with him that she'd regretted? Or maybe Chad had attacked Alexandra. His service record was clean-certainly no a.s.sault charges-but that didn't mean the two didn't have a history together. And then when he saw her face pop up out of the blue, he'd gone after Nadia. I knew I was committed to Chad's innocence, but these connections did not look innocent. Maybe Terry Finchley was right after all. Maybe Chad had doped his own beer out of guilt over murdering Nadia. If that was the case, though, who had broken into her apartment yesterday?

The ideas spun round and round, uselessly, like wheels unable to find traction in a s...o...b..nk. Frustrated, I looked up reports on Tintrey.

If I couldn't find enough about Alexandra, I had the opposite problem with the company that took her to Iraq. I started with their website, which showed heroic warriors defending America from terrorists in the Middle East and Africa but also stressed that "Tintrey is more than just a group of highly skilled fighting men and women. We're there when you need us . . . whether it's at the PX or the RX."

Tintrey provided base security, they had a division that produced protective gear, they built base housing, they bodyguarded visiting VIPs, and they helped staff the post exchanges.
