‘Guess where the young man lived? South Lexington. Within five blocks of where the two women were found. I’m telling you, there’s something new, something that’s killing off junkies. And South Lexington seems to be its point of origin. Here’s what I think you should do, Davis. Get on the phone to the mayor. Call a joint press conference. Get the news out before we get more John and Jane Does cluttering up my basement.’

‘I don’t know.’

‘What don’t you know?’

‘It could be a single batch. Maybe that’s all it is.’

‘Or maybe there’s a whole ton of the stuff sitting in some pusher’s warehouse.’

Agitated, Wheelock sat back and ran his hand through his gray hair. ‘All right. I’ll talk to the mayor. It’s a bad time to be bringing this up, what with the city bicentennial and all. He’s launching his campaign this week—’

‘Davis. People are dying.’

‘All right, all right. I’ll call him this afternoon.’

Satisfied that she’d made her point, Kat left Wheelock’s office and headed down to the basement. In the corridor, two of the overhead fluorescent lights flickered like a strobe flash. Everything seemed to be wearing down, wearing out. The building. The city.

And there they were, celebrating the bicentennial. What are we celebrating exactly, Mr. Mayor? Two hundred years of decline?

Back in her office, Kat considered drinking the last dregs of the coffee pot. No, she wasn’t that desperate. Two files lay on her desk, files she couldn’t complete, perhaps would never be able to complete. One was Jane Doe’s. The other was for Xenia Vargas, the second woman from South Lexington. She, at least, had been found with ID in her purse, though they hadn’t yet confirmed Vargas was really her name. Nor had they been able to contact any relatives.

Two dead women. And no one who could tell her how – or why – they had died.

On a corner of her desk was a notepad, with the name Dr. Michael Dietz scribbled on it. He was the ER doctor she’d spoken to earlier, the one who’d admitted the male overdose victim at Hancock General.

It was five o’clock; she could hear the evening morgue attendants laughing in the prep room, enjoying the brief and blessed lull before the madness of nightfall.

Kat changed into her street clothes, pulled on her coat, and left the building.

She didn’t drive home. Instead, she drove to South Lexington, to Hancock General Hospital.

It sat like a fortress in a war zone, its parking lot surrounded by a barbed wire fence, the front entrance overhung by surveillance cameras. The ER clerk was sitting behind glass – bulletproof, Kat surmised. He spoke through a microphone; the tinny voice coming through the speaker made Kat think of a McDonald’s drive-through. ‘How can I help you?’ he asked.

‘I’m Dr. Novak,’ she said. ‘ME’s office. I want to see a Dr. Michael Dietz. It’s about a patient of his.’

‘I’ll page him.’

Dr. Dietz emerged a few minutes later, looking like some weary veteran of the trenches. A stethoscope was looped around his neck, and his scrub pants were splattered with blood. ‘You just caught me,’ he said. ‘I was going off shift. You’re from the ME?’

‘We talked earlier. About that overdose.’

‘Oh, yeah. He’s up in Intensive Care. I can’t remember his name . . .’

‘Can we go up to the Unit?’ she asked. ‘I’d like to look over his chart.’

‘I guess it’s okay. Seeing as you’re official and all.’

They headed to the elevators. The hospital looked the same as Kat remembered it, dingy linoleum floors, halls painted a bizarre aqua color, gurneys shoved up against the walls. Through the doorway on the right was the cafeteria, with its echoes of clinking dishes and scraping chairs. On the overhead paging system, a bored voice read out a list of doctors’ names and extension numbers. Dr. Dietz moved like a sleepwalker in tennis shoes.

‘I see the place hasn’t changed any,’ said Kat.

‘Did you use to work here?’

‘No. I did my residency over at St. Luke’s. But I knew a patient here. A relative.’

He laughed. ‘I’m not sure I’d want any of my relatives here.’

‘Didn’t matter to her. She didn’t know where she was, anyway.’

They stepped into the staff elevator and crowded in beside nurses and orderlies. Everyone stared straight ahead, as though mesmerized by the changing floor numbers.

‘So are you from the city?’ asked Dietz.

‘A native. And you?’

‘Cleveland. I’m going back.’

‘Don’t like it here?’

‘Let’s put it this way. Compared to this town, Cleveland is the Garden of Eden.’

They got off on the third floor and headed into Intensive Care.

The Unit was set up like a giant stable, with stalls marked out by curtains. Only two beds were empty, Kat noted; not much preparation for an unexpected disaster. And there was a full moon. That was always a harbinger of a busy night.

The patient was in bed thirteen. Only comatose patients went into that bed, Dietz said. Why scare some conscious patient? When you’re fighting for your life, even dumb superstitions take on frightening significance.

The man’s name was Nicos Biagi. He was a husky fellow, about twenty, with biceps and pectorals that had obviously done time in the weight-rooms. There were seven tubes snaking out of various parts of his body – a grim prognostic indicator. He lay utterly flaccid. According to the chart, he was unresponsive to even the most intense of stimuli.

‘Twenty-four hours and not a twitch,’ said the nurse. ‘Plus, we’re having trouble stabilizing his pressure. It goes haywire on us, shoots up, then bottoms out. I’m going crazy, juggling all these meds.’

Kat flipped through the chart, quickly deciphering the hurried notes of the ICU resident. The patient had been found unconscious in his car, parked outside his parents’ apartment. He’d been sprawled on the front seat. Beside him on the floor had been his kit: a tourniquet, syringe and needle, spoon, and cigarette lighter. Somehow, during the frantic rush to stabilize the patient and transport him to the ER, the EMTs had lost track of the syringe. They thought the family might have it; the family claimed the EMTs had it. The police said they’d never even seen it. In any event, the blood toxicology screen would provide the answers.

At least, it should.

They’d found out a few things. A 0.13 ethanol level proved the man was legally drunk. Also, he’d been pumped full of steroids – something Kat could have guessed, judging from those bulging biceps. What the tests hadn’t answered was the primary question: Which drug had put him into the coma?

All the usual medical steps had been taken. Despite a treatment of glucose, Narcan, and thiamine, he hadn’t awakened. The only therapeutic strategy left was supportive: maintain his blood pressure, breathe for him, keep his heart beating. The rest was up to the patient.

‘You have no history at all?’ asked Kat. ‘Nothing about what he shot up? Where he got it from?’

‘Not a thing. His parents are in the dark. They had no idea their kid was a junkie. That’s probably why he did it in the car. So they wouldn’t know about it.’

‘I’ve got two women in the morgue. Both with the same biphasic peak on gas chromatography. Like your man.’

Dietz sighed. ‘Terrific. Another wonder drug hits our streets.’

‘When will your final tox report be done?’

‘I don’t know. It’s been twenty-four hours already. If this is something new, it may take weeks to identify. These pharmaceutical whizzes out there crank out drugs like new shoes. By the time we catch up with the latest fad, they’re on to something else.’

‘You agree, then? That it’s something new?’

‘Oh, yeah. I’ve seen it all come down the pike. PCP, tropical ice, fruit loops. This is something different. Something bad. I think the only reason this guy’s still alive, and your two women aren’t, is that he’s a big dude. All that muscle mass. Takes a bigger dose to kill him.’

It still might kill him, thought Kat, gazing at the comatose patient.

‘If this goes to the media, can I use you as a source?’ she asked.

‘What do you mean?’

‘I think a warning ought to go out on the streets. That there’s bad stuff making the rounds.’

Dietz didn’t answer right away. He just kept looking at Nicos Biagi. ‘I don’t know,’ he said at last.

‘What do you mean, you don’t know? It’d just be to voice your opinion. To confirm my statement.’

‘I don’t know,’ he said again. He was gripping the IV pole. ‘It’s not as if you need me. You’ve got the authority.’

‘I could use the backup.’

‘It’s just . . . the press. I’m not crazy about talking to them.’

‘Okay, then just let me cite you by name. Would that be okay?’

He sighed. ‘I guess so. But I’d rather you didn’t.’ Abruptly, he straightened and glanced at his watch. ‘Look, I have to get going. I’ll catch you later.’

Kat watched him walk out of the ICU, his shoulders hunched forward as though his whole body was straining to break into a sprint. What was he afraid of? she wondered. Why wouldn’t he talk to the press?

She was on her way out of the ICU when she spotted the Biagis, coming in to visit their son. She guessed at once who they were, just by the grief in their faces. Mrs. Biagi was dark-haired, dark-eyed, and her face was seamed with worry. Mr. Biagi was much older and bald; he looked too numb to be feeling much of anything at the moment. They went to Nicos’s bedside, where they stood for a moment in silence. Mrs. Biagi stroked her son’s hair and began to sing softly, something in Italian. A lullaby, perhaps. Then she faltered, dropped her head to her son’s chest, and began to cry.

Mr. Biagi didn’t say a word.

Kat walked out of the ICU.

In her haste to leave behind that scene, she took a wrong turn in the hallway. Instead of heading to the elevators, she found herself in a different wing, a part of the hospital she hadn’t seen before. White walls and gleaming linoleum told her this was a new addition, constructed only recently. Behind a glass case on the wall were displayed various mementoes of the wing’s opening: photographs of hospital officials at the ribbon cutting. Shots of a celebrity black-tie dinner. A bronze plaque, engraved with The Georgina Quantrell Wing. And a newspaper article with the headline: Cygnus president dedicates multimillion-dollar drug rehab addition. The accompanying photograph showed a sober-faced Adam Quantrell, posing beside the plaque.

For a long time, Kat stood by that case, studying the photos, the news articles. Drug rehab? A surprising crusade for a man who made his fortune from drugs. Her gaze traveled the length of the case, paused at a teaching display of commonly abused drugs. Mounted on the board was a multicolored variety of capsules. And below it was the label: Display courtesy of the Cygnus Company.

Something clicked in Kat’s head. Dead junkies. A new drug on the street. Cygnus Pharmaceuticals.

And a matchbook with Adam Quantrell’s phone number.

She reached for her cell phone, and called Sykes in Homicide.

He was just leaving for home and did not seem particularly eager to prolong his work day.

‘Let me put it this way, Novak,’ he said. ‘In the grand scheme of things, drug ODs are not high on my list of priorities.’

‘Think about it, Lou. What’s an addict doing with Quantrell’s personal phone number? Why was Quantrell so eager to look at the body? He’s hiding something.’

‘No, he’s not.’

‘I think he is.’

‘They were junkies, Novak. They lived on the edge, they fell off. It’s not homicide. It’s not suicide. It’s stupidity. Social Darwinism, survival of the smartest.’

‘Maybe that’s what you think. Maybe that’s what Quantrell thinks. But I’ve still got two dead women.’

‘Forget Quantrell. The man’s into drug rehab, not drug pushing.’

‘Lou, this is a new drug. I spoke to an ER doctor here who says he’s never seen it before. To cook up a brand new drug, you need a biochemist. And a lab. And a factory. Cygnus has it all.’

‘It’s a legitimate company.’

‘With maybe an illegitimate branch?’

‘Christ, Novak. I’m not going to hassle Quantrell.’

‘I heard you did a favor for him. On the side.’

There was a pause. ‘Yeah. So what?’

‘So what were you doing for him out in South Lexington?’

‘Look, you want to hear the details?’ Sykes snapped. ‘Then you talk to him.’ He hung up.

Kat stared at the phone. Well, maybe she had pushed Lou too far on this one. My big mouth, she thought. One of these days it’s going to get me into trouble.

Slipping her cell phone into her pocket, she saw Mr. and Mrs. Biagi coming out of the ICU. They were leaning on each other, holding each other up, as though grief had sapped all their strength.

Kat thought of their son Nicos, with the seven tubes in his body. She thought of Jane Doe and Xenia Vargas, both relegated to the approximate level of primordial muck in Sykes’ scale of social Darwinism. Something was killing these people, something that had sunk its evil roots into the Projects.

Her old neighborhood.

On her way back to the freeway, she drove up South Lexington. In the last few years, nothing had changed. The seven Project buildings still looked like prison towers, the playground still had a bent basketball hoop, and teenagers still hung out on the corner of Franklin and South Lexington. But the faces were different. It wasn’t just that these were different people. There was a new hardness to their gazes, a wariness, as they watched her drive by. Only then did the thought strike her.

To them she was an outsider. Someone to be watched, someone to be guarded against. Someone not to be trusted.

She continued up South Lexington and took the freeway on-ramp.

Traffic was still heavy moving north. It was the evening exodus to the suburbs, a daily hemorrhage of white-collar types to Bellemeade, Parris, Clarendon, and Surry Heights. Those who could afford to flee, fled. Even Kat, a city girl born and bred, now called the suburbs home. Just last year, she’d bought a house in Bellemeade. It seemed a logical move, financially speaking, and she’d reached the point in life when she had to make a commitment – any commitment, even if it was only to a three-bedroom cape. Bellemeade was a hybrid neighborhood, close enough to town to make it feel like part of the city, yet far enough away to put it squarely in the safety of the suburbs.

On impulse, she bypassed the Bellemeade turnoff and stayed on the freeway. It took her a half hour to drive to Surry Heights.

Along the way, the traffic thinned out, the scenery changed. Cookie-cutter houses gave way to trees and rolling hills, newly green from those proverbial April showers. White fences and horses appeared – a sure harbinger of old money. She took the Surry Heights exit onto Fair Wind Lane.

Two miles down the road she came to the Quantrell residence. There was no mistaking the place. Two stone pillars flanked the driveway entrance; the name Quantrell was spelled out in wrought iron lettering mounted on one of the pillars. The gate hung open to visitors. Kat drove through, and followed the curving driveway to the house.

There were three cars parked out front, a Jaguar and two Mercedes. She parked her five-year-old Subaru next to the Jag and climbed out. Nice paint job, she thought, eyeing the Jag’s burgundy finish. The interior was spotless, with not a clue to its owner’s personality in sight. No bumper stickers, either, though one that said Let them eat cake would have been appropriate.

She went to the front door and rang the bell. It pealed like a church chime in a cavern.

The door opened, and a man wearing a butler-type uniform gazed down at her. ‘Yes?’ he said.

Kat cleared her throat. ‘I’m Dr. Novak. Medical examiner’s office. I wonder if I could speak to Mr. Adam Quantrell.’

‘Is Mr. Quantrell expecting you?’

‘No. But I’m here on official business.’

For a moment the man seemed to consider her request. Then he opened the door wider. ‘Come in.’

Surprised at how easy that was, she stepped inside. In wonder, she gazed up at a crystal chandelier. It was just a modest little entry hall, she thought. Nothing you wouldn’t find in a typical castle. The floor was gleaming terrazzo, and a massive banister traced a staircase to a second-floor gallery. Paintings – mostly modern, vaguely disturbing, wild blots of color – hung in various places of honor.

‘If you’ll wait here,’ said the butler.

He disappeared through a side door. She heard the distant sound of a woman’s laughter, the strains of classical music. Oh, great. He’s got a party going, she thought. Terrific timing, Novak.

She turned as she heard footsteps. Adam Quantrell emerged from a side room, quietly shutting the door behind him. He was dressed formally, black tie, ruffled white shirt. He did not look pleased to see her.

‘Dr. Novak,’ he said. ‘Is this urgent? Or can it wait till some other time?’

‘I think it’s urgent.’

‘More questions?’ he asked.

‘And another body.’

She watched for his reaction and was not at all surprised to see his face flinch. After a pause he said, ‘Whose?’

‘A woman. They found her not too far from where they found the first one. In a stairwell off South Lexington. It looks like another drug OD.’

He still looked stunned. ‘Do you . . . want me to come down and look at her?’

‘Not necessarily. But maybe you’ll know the name. She had her purse with her. The driver’s license said Xenia Vargas. I assume it’s hers because the photo matched the corpse. Does that name ring a bell?’

He let out a breath. She wondered if it was a sigh of relief.

‘No,’ he said. ‘I don’t know that name.’

‘What about the name Nicos Biagi?’

‘I don’t know that name either. Why?’

‘Just curious.’

Adam reacted with a snort of disbelief. ‘You show up at my door and assault me with the names of corpses, just to see how I react. And all because you’re curious?’

‘Who said Nicos Biagi was a corpse?’

‘I don’t know who the hell he is! I just assumed. Everyone else you mention seems to be a corpse!’ His voice seemed to echo off the terrazzo floor and bounce around the far reaches of the vast entrance hall. At once he regained his composure, his face settling into an expression of cool unreadability. ‘So,’ he said. ‘Who is Nicos Biagi? And is he or is he not a corpse?’

‘Nicos happens to be alive – barely,’ she said. ‘He’s a patient at Hancock General. A drug OD. We’re worried about the drug. It seems to be something new, and it’s already killed Jane Doe and Xenia Vargas. It’s left Nicos Biagi critically ill. I wondered if you knew something about it.’

‘Why would I?’

‘A hunch.’

To her annoyance, he laughed. ‘I hope this isn’t the way the ME’s office usually conducts business. Because if it is, our criminal justice system is in big trouble.’

The side door opened again. A woman appeared, looking quizzical. And gorgeous. Her evening dress, shot through with gold thread, seemed to glitter in the chandelier light. Her hair, an equally brilliant gold, fell in ripples to her shoulders. She glanced at Adam’s visitor, a look that Kat recognized at once for what it was – a feminine sizing-up, then a curt dismissal. ‘Adam?’ she asked. ‘Is something wrong?’

‘No,’ he said, his gaze still fixed on Kat. ‘It’s just – business.’

‘Oh.’ The woman smiled sweetly. ‘Pearl just brought out the soup. And we didn’t want to start without you.’

‘Sorry, Isabel. Why don’t you all just go ahead with supper? Dr. Novak and I aren’t finished yet.’

Again, her gaze shifted to Kat. ‘We can set another place, if you’d like. For your visitor.’

There was an awkward silence, as though Adam were hunting for a graceful way to avoid inviting this unwelcome guest.

‘That won’t be necessary,’ said Kat, and thought she saw a look of relief cross Adam’s face. ‘I’ll be leaving, as soon as we’re done with our . . . business.’

Isabel smiled again, as though equally relieved. ‘Join us when you can, Adam,’ she said, and withdrew into the side room.

Adam and Kat regarded each other for a moment.

‘Let’s talk in the study,’ he said, and abruptly turned and opened another door. She followed him inside.

It was a characteristically masculine space, dark and clubby, with a fireplace and wood paneling, the sort of room in which one smoked pipes and drank cognac. She sat on the leather couch. He didn’t sit at all, but paced in front of the fireplace. The longer she watched him, the more annoyed she felt. It was irrational, of course, but she was insulted that he hadn’t offered her a place at the supper table. She would have turned it down, of course; you didn’t just drop into a formal supper, and judging from Isabel’s evening gown, this was no potluck they were serving. But at least she would have had the pleasure of turning him down. It was a matter of pride.

‘So what’s the basis for this hunch of yours?’ he demanded. ‘Why do you think I would know anything about it?’

‘Because of that matchbook.’

‘Not much of a reason.’

‘Because this is a new drug, never seen before.’

He shrugged. ‘So?’

‘And because you’re president of Cygnus Pharmaceuticals. A company known for its R and D in painkillers. A company that just released a new class of opiates.’

‘We also make drugs for athlete’s foot.’

‘Oh, and one more thing.’

‘Yes?’ When he tilted his head his blond hair caught the glow of the table lamp.

‘Until you saw the body, you thought Jane Doe was someone you might know.’

At once he fell silent, all trace of mockery gone from his face. He sat down, his gaze avoiding hers.

‘Who did you think she was, Mr. Quantrell?’

‘Someone . . . close to me.’

‘What’s the secret here? Why can’t you just say who you thought she was?’

‘These are things I don’t wish to discuss. Not with a stranger.’

‘Then can you discuss the drug? It’s something new. A narcotic with a biphasic peak on gas chromatography. Could it be something that leaked out of Cygnus? Something you’re developing?’

‘I wouldn’t want to speculate.’

Of course he wouldn’t. Because then he’d be vulnerable to all sorts of accusations. The manufacture of lethal drugs. The slaughter of junkies.

Slowly he looked up. ‘You said you had another body in the morgue. A woman.’

‘Xenia Vargas.’

‘Is she . . . young?’

‘About twenty.’

‘Describe her for me.’

‘You think you might know her?’

‘Please. Just tell me what she looks like.’

Something about the tone of his voice, the stifled note of anxiety, made her feel sorry for him. ‘She’s about five foot four, on the thin side. Dark brown hair—’

‘Could it be dyed?’

Kat paused. ‘It’s possible, I guess.’

‘What about her eyes? What color?’

‘Hazel.’

Another silence. Then, with sudden agitation, he rose to his feet. ‘I think I’d better see her,’ he said.

‘You mean – now?’

‘If we could.’ He met her gaze. ‘If you’d be so kind.’

She too stood up and followed him into the main hall. ‘What about your dinner guests?’

‘They can feed themselves. Would you excuse me a moment, while I gracefully duck out?’

He went through the side door, but this time he left it open. Kat caught a glimpse of a formal dining room and a half-dozen guests seated around the table. Some of them glanced curiously in Kat’s direction. She heard Isabel ask, ‘Should I wait for you, Adam?’

‘Please don’t,’ he said. ‘I don’t know how long I’ll be.’

‘This is really quite naughty of you, you know.’

‘It can’t be helped. Good night, everyone! You’re free to have a go at my wine cellar, but leave me a few bottles, will you?’ He clapped one of the men on the shoulder, waved farewell, and came back into the hall, shutting the door behind him.

‘That’s done,’ he said to Kat. ‘Now. Let’s go.’
