The chopper came in low over the East River. The dark water was beneath them, flowing fast, tiny swells rising and falling. Luke could see what Ed meant. The water looked like a thousand rats running under a black shimmering blanket.

They dropped slowly down to the 34^th Street heliport. Luke watched the lights of the buildings to his left, a million twinkling jewels in the night. Now that they were here, a sense of urgency surged through him. His heart skipped a beat. He had stayed calm during the long flight because what else was he going to do? But the clock was ticking, and they needed to move. He could almost jump out of the helicopter before it landed.

It touched down with a bump and a shudder, and instantly everyone in the cabin unbuckled. Don wrenched the door open. “Let’s go,” he said.

The blast gate to the street was twenty yards from the pad. Three SUVs waited just outside the concrete barriers. A squad of New York SRT guys ran to the helicopter and off-loaded the equipment bags. A man took Luke’s garment bag and his bug-out bag.

“Careful with those,” Luke said. “The last time I came up here, you guys lost my bags. I’m not going to have time for a shopping trip.”

Luke and Don climbed into the lead SUV, Trudy sliding in with them. The SUV was stretched to create a passenger cabin with facing seats. Luke and Don faced forward while Trudy faced backward. The SUV rolled out almost before they sat down. Within a minute they were inside the narrow canyon of FDR Drive, racing north. Yellow taxis zoomed all around them, like a swarm of bees.

No one spoke. The SUV raced along, hugging the concrete curves, passing through tunnels beneath crumbling buildings, banging hard over potholes. Luke could feel his heart beat in his chest. The driving wasn’t what made his pulse race. It was the anticipation.

“It would have been nice to come up here for a little fun,” Don said. “Stay in a fancy hotel, maybe see a Broadway show.”

“Next time,” Luke said.

Outside his window, the SUV was already exiting the highway. It was the 96^th Street exit. The driver barely paused at a red light, then turned left and floored it down the empty boulevard.

Luke watched as the SUV roared into the circular driveway of the hospital. It was a quiet time of night. They pulled directly in front of the bright lights of the emergency room. A man in a three-piece suit stood waiting for them.

“Sharp dresser,” Luke said.

Don poked Luke with a thick finger. “Say, Luke. We got a little treat for you tonight. When was the last time you put on a hazmat suit?”

Chapter 4

4:11 a.m.

Beneath Center Medical Center, Upper East Side

“Not too tight,” Luke said around a mouthful of plastic thermometer.

Trudy had placed the sensor of a portable blood pressure monitor on Luke’s wrist. The sensor squeezed his wrist hard and then harder still, then slowly released it in stages, making gasping sounds as it did so. Trudy tore back the Velcro on the wrist sensor and in almost the same motion, pulled the thermometer from his mouth.

“How does it look?” he said.

She glanced at the readouts. “Your blood pressure is up,” she said. “138 over 85. Resting heart rate 97. Temperature 100.4. I’m not going to lie to you, Luke. These numbers could be better.”

“I’ve been under a little stress lately,” Luke said.

Trudy shrugged. “Don’s numbers are better than yours.”

“Yeah, but he takes statins.”

Luke and Don sat together in their boxers and T-shirts on a wooden bench. They were in a sub-basement storage facility beneath the hospital. Heavy vinyl drapes hung all around them, closing off the area. It was cold and dank down here, and a shiver raced along Luke’s spine. The breached containment vault was two stories further below them.

People milled around. There were a couple of SRT guys from the New York office. The SRT guys had set up two folding tables with a series of laptops and video displays across them. There was the guy in the three-piece suit, who was an intelligence officer from the NYPD counter-terrorism unit.

Ed Newsam, the big weapons and tactics guy Luke had met on the chopper, pushed through the vinyl curtains with two more SRT guys behind him. Each SRT man carried a sealed clear package with bright yellow material inside.

“Attention,” Newsam said in a loud voice, cutting through the chatter. He pointed two fingers at his own eyes. “Don and Luke, eyes on me, please.”

Newsam held a bottle of water in each hand. “I know you’ve both done this before, but we’re going to treat it like the first time, that way there’s no mistakes. These men behind me are going to inspect your suits for you, and then they’re going to help you put them on. These are Level A hazmat suits, and they’re solid vinyl. It’s going to get hot inside of them, and that means you’re going to sweat. So before we begin, I need you to start drinking these bottles of water. You will be glad you did.”

“Has anyone been down there before us?” Luke said.

“Two guards went down after the security breach was discovered. The lights are knocked out. Swann has tried to bring them back on, but no luck. So it’s dark down there. The guards had flashlights, but when they found the vault open and canisters and drums strewn around, they backed out in a hurry.”

“They get any exposure?”

Newsam smiled. “A little. My daughters are going to use them as nightlights for a few days. They didn’t have suits on, but they were only there for a minute. You’re going to be down there longer.”

“Will you be able to see what we see?”

“Your hoods have mounted videocams and LED lights. I’ll see what you’re seeing, and I’ll be recording it.”

It took twenty minutes to get dressed. Luke was frustrated. It was hard to move inside the suit. He was covered head to toe in vinyl, and it was already getting hot inside. His face plate kept fogging up. It seemed like time was flying past them. The thieves were far out ahead.

He and Don rode the freight elevator together. It creaked slowly downward. Don carried the Geiger counter. It looked like a small car battery with a carry handle.

“You guys hear me okay?” Newsam said. It sounded like he was inside Luke’s head. The hoods had built-in speakers and microphones.

“Yeah,” Luke said.

“I hear you,” Don said.

“Good. I hear you both loud and clear. We’re on a closed frequency. The only people on here are you guys, me, and Swann up in the video control booth. Swann has access to a digital map of the facility and those suits are outfitted with tracking devices. Swann can see you on his map, and he’s going to direct you from the elevator to the vault. You with me, Swann?”

“I’m here,” Swann said.

The elevator lurched to a stop.

“When the doors open, step out and turn left.”

The two men moved awkwardly down a wide hallway, guided by Swann’s voce. Their helmet lights played against the walls, throwing shadows in the dark. It reminded Luke of shipwreck scuba dives he had done in years past.

Within a few seconds, the Geiger counter started to click. The clicks came spaced apart at first, like a slow heartbeat.

“We have radiation,” Don said.

“We see it. Don’t worry. It’s not bad. That’s a sensitive machine you’re carrying.”

The clicks started to speed up and grow louder.

Swann’s voice: “In a few feet, turn right, then follow that hallway maybe thirty feet. It will open into a large square chamber. The containment vault is on the other side of the chamber.”

When they turned right, the Geiger counter began to click loud and fast. The clicks came in a torrent. It was hard to tell one from the next.

“Newsam?”

“Step lively, gentlemen. Let’s try to do this in five minutes or less.”

They moved into the chamber. The place was a mess. On the floor, canisters, boxes, and large metal drums were knocked over and left randomly. Some of them were open. Luke trained his light on the vault across the room. The heavy door was open.

“You seeing this?” Luke said. “Godzilla must have passed through here.”

Newsam’s voice came in again. “Don! Don! Train your light and your camera on the ground, five feet ahead. There. A few more feet. What’s that on the floor?”

Luke turned toward Don and focused his light in the same place. About ten feet from him, amid the wreckage, were sprawled what looked like a pile of rags.

“It’s a body,” Don said. “Shit.”

Luke moved over to it and trained his light on it. The person was big, wearing what looked like a security guard’s uniform. Luke kneeled beside the body. There was a dark stain on the floor, like a bad motor oil leak under a car. The head was sideways, facing him. Everything above the eyes was gone, his forehead blown out in a crater. Luke reached around to the back of the head, feeling for a much smaller hole. Even through the thick chemical gloves, he found it.

“What do you have, Luke?”

“I have a large male, 18 to 30 years old, of Arab, Persian, or possibly Mediterranean descent. There’s a lot of blood. He’s got entry and exit wounds consistent with a gunshot to the back of the head. It looks like an execution. Could be another guard or it could be one of our subjects had an argument with his friends.”

“Luke,” Newsam said. “In your utility belt, you’ve got a small digital fingerprint scanner. See if you can dig it out and get a print off that guy.”

“I don’t think that’s going to be possible,” Luke said.

“Come on, man. The gloves are cumbersome, but I know where the scanner is. I can walk you to it.”

Luke pointed his camera at the man’s right hand. Each finger was a ragged stump, gone below the first knuckle. He glanced at the other hand. It was the same way.

“They took the fingerprints with them,” he said.

Chapter 5

Luke and Don, dressed in street clothes again, walked quickly down the hospital corridor with the sharp dresser from the NYPD counter-terrorism unit. Luke hadn’t even caught the guy’s name. He thought of him as Three-Piece. Luke was about to give the guy his orders. They needed things to happen, and for that they needed the city’s cooperation.

Luke was taking charge, like he always tended to do. He glanced at Don, and Don nodded his assent. That’s why Don brought Luke on: to take charge. Don always said that Luke was born to play quarterback.

“I want Geiger counters on every floor,” Luke said. “Somewhere away from the public. We didn’t hit any radiation until six levels down, but if it starts to move upward, we need everyone out, and fast.”

“The hospital has patients on life support,” Three-Piece said. “They’re hard to move.”

“Right. So start putting those logistics in place now.”

“Okay.”

Luke went on. “We’re going to need an entire hazmat team down there. We need that body brought up, no matter how contaminated, and we need it done fast. The clean-up can wait until after we have the body.”

“Got it,” Three-Piece said. “We’ll put it in a lead-lined casket, and bring it to the coroner in a radiation containment truck.”

“Can it be done quietly?”

“Sure.”

“We need a match for dental records, DNA, scars, tattoos, surgical pins, whatever we can find. Once you have the data, pass it on to Trudy Wellington on our team. She’s got access to databases your people won’t have.”

Luke pulled out his phone and speed-dialed a number. She picked up on the first ring.

“Trudy, where are you?”

“I’m with Swann on Fifth Avenue, in the back of one of our cars, on our way down to the command center.”

“Listen, I’ve got…” He looked at Three-Piece. “What’s your name?”

“Kurt. Kurt Myerson.”

“I’ve got Kurt Myerson from the NYPD here. He’s with the counter-terrorism unit. They’re going to bring the body up. I need you to connect with him for dental records, DNA, any identifiers at all. When you get the data, I want this guy’s name, age, country of origin, known associates, everything. I need to know where’s he been and what he’s been doing for the past six months. And I need all of this yesterday.”

“Got it, Luke.”

“Great. Thank you. Here’s Kurt, he’s going to give you his direct number.”

Luke handed Kurt the phone. The three men pushed through a set of double doors, barely slowing down. In a moment, Kurt handed the phone back to Luke.

“Trudy? You still with me?”

“Would I ever be anywhere else?”

Luke nodded. “Good. One more thought. The surveillance cameras are off here at the hospital, but there’s got to be cameras all over this neighborhood. When you get to the command center, grab a few of our people. Have them access anything they can find within a five-block radius of this place, and pull video from, let’s say, 8 p.m. until 1 a.m. I want to get a look at every commercial or delivery vehicle that came near the hospital during that time. Highest priority is small delivery vans, bread trucks, hot dog trucks, anything along those lines. Anything small, convenient, that can carry a concealed payload. Lower priority is tractor trailers, buses, or construction vehicles, but don’t overlook them. Lowest priority is RVs, pickup trucks, and SUVs. I want screen captures of license plates, and I want ownership of the vehicles tracked. If you find one that looks fishy, you search more cameras for that vehicle on an expanding radius, and find out where it went.”

“Luke,” she said, “I’m going to need more than a few people for that.”

Luke thought about it for two seconds. “Okay. Wake up some people back home, bring them in to SRT headquarters, and forward the license plate data to them. They can track ownership down there.”

“Got it.”

They hung up. Luke reoriented himself to the present moment, and a new thought occurred to him. He glanced at Kurt Myerson.

“Okay, Kurt. Here’s the most important thing. We need this hospital locked down. We need the employees who were on shift tonight gathered up and sequestered. People are going to talk, I understand that, but we’ve got to keep this out of the hands of the media for as long as we can. If this gets out, there’s going to be panic, there’s going to be ten thousand false leads called in to the police, and the bad guys will get to watch the entire investigation unfold on television. We can’t let it happen.”

They pushed through another set of double doors and into the main lobby of the hospital. The entire front face of the lobby was glass. Several security guards stood near the locked front doors.

Outside was a mob scene. A crowd of reporters pushed up against police barriers on the sidewalk. Photographers pressed against the windows, taking interior shots of the lobby. News trucks were parked ten deep on the street. As Luke watched, three different TV reporters filmed segments directly in front of the hospital.

“You were saying?”

Chapter 6

5:10 a.m.

Inside a van

Eldrick was sick.

He sat in the rear passenger seat of the van, hugging his knees, wondering what he had gotten himself into. He had seen some bad shit in prison, but nothing like this.

In front of him, Ezatullah was on the phone, shouting something in Farsi. Ezatullah had been making calls for hours now. The words didn’t mean anything to Eldrick. It all sounded like gibberish. The real deal, Ezatullah had trained in London as a chemical engineer, but instead of getting a job, he had gone to war. In his early 30s, a wide scar across one cheek, to hear him tell it, he had waged jihad in half a dozen countries – and had come to America to do the same.

He screamed into the phone again and again before he got through. When he finally reached someone, he launched into the first of several shouted arguments. After a few minutes, he settled down and listened. Then he hung up.

Eldrick’s face was flushed. He had a fever. He could feel it burning through his body. His heart was racing. He hadn’t thrown up, but he felt like he was going to. They had waited at the rendezvous point on the South Bronx waterfront for over two hours. It was supposed to be a simple thing. Steal the materials, drive the van ten minutes, meet the contacts and walk away. But the contacts never showed.

Now they were…somewhere. Eldrick didn’t know. He had passed out for a while. He was awake again, but everything seemed like a vague dream. They were on the highway. Momo was driving, so he must know where they were going. A technology expert, Momo, skinny with no muscle tone, looked the part. He was so young the smooth skin of his face didn’t have a single line. He looked like he couldn’t grow a beard if Allah himself depended on it.

“We have new instructions,” Ezatullah said.

Eldrick groaned, wishing he was dead. He didn’t know it was possible to feel this sick.

“I have to get out of this van,” Eldrick said.

“Shut up, Abdul!”

Eldrick had forgotten: his name was Abdul Malik now. It felt weird to hear himself being called Abdul, he, Eldrick, a proud black man, a proud American for most of his life. Feeling as sick as he did now, he wished he’d never changed it. Converting in prison was the dumbest thing he’d ever done.

All that shit was in the back. There was a lot of it, in all kinds of canisters and boxes. Some of it had leaked out, and now it was killing them. It had killed Bibi already. The dummy had opened a canister when they still were down in the vault. He was immensely strong and he wrenched the lid off. Why did he do that? Eldrick could picture him holding the canister up. “There’s nothing in here,” he’d said. Then he’d held it to his nose.

Within a minute, he started coughing. He just sort of sank down to his knees. Then he was on all fours, coughing. “I have something in my lungs,” he said. “I can’t get it out.” He started gasping for air. The sound was horrible.

Ezatullah walked up and shot him in the back of the head.

“Believe me, I did him a favor,” he’d said.

Now, the van was passing through a tunnel. The tunnel was long and narrow and dark, with orange lights zooming by overhead. The lights made Eldrick dizzy.

“I have to get out of this van!” he shouted. “I have to get out of this van! I have to…”

Ezatullah turned around. His gun was out. He pointed it at Eldrick’s head.

“Quiet! I’m on the phone.”

Ezatullah’s sliced up face was flushed red. He was sweating.

“You gonna kill me the way you did Bibi?”

“Ibrahim was my friend,” Ezatullah said. “I killed him out of mercy. I will kill you just to shut you up.” He pressed the muzzle of the gun against Eldrick’s forehead.

“Shoot me. I don’t care.” Eldrick closed his eyes.

When he opened them again, Ezatullah had turned back around. They were still in the tunnel. The lights were too much. A sudden wave of nausea passed through Eldrick, and a great up-rushing spasm gripped his body. His stomach clenched and he tasted acid in his throat. He bent over and threw up on the floor between his shoes.

A few seconds passed. The stench wafted up into his face, and he wretched again.

Oh God, he begged silently. Please let me die.

Chapter 7

5:33 a.m.

East Harlem, Borough of Manhattan

Luke held his breath. Loud noises were not his favorite thing, and one hell of a loud noise was coming.

He stood completely still in the bleak light of a tenement building in Harlem. His gun was out, his back pressed to the wall. Behind him, Ed Newsam stood in almost the exact same pose as his. In front of them in the narrow hallway, half a dozen helmeted and flak-jacketed SWAT team members stood on either side of an apartment door.

The building was dead quiet. Dust motes hung in the air. Moments before, a small robot had slid a tiny camera scope beneath the door, looking for explosives attached to the other side. Negative. Now, the robot had retreated.

Two SWAT guys stepped up with a heavy battering ram. It was a swing-type, an officer holding the handle on each side. They didn’t make a sound. The SWAT team leader held up his fist. His index finger appeared.

That was one.

Middle finger. Two.

Ring finger…

The two men reared back and swung the ram. BAM!

The door exploded inward as the rammers ducked back. The four others swarmed in, suddenly shrieking, “Down! Down! Get DOWN!”

Somewhere down the hallway, a child started crying. Doors opened, heads peeped out, then ducked back in. It was one of those things around here. Sometimes the cops came and broke down a neighbor’s door.

Luke and Ed waited about thirty seconds until SWAT had secured the apartment. The body was on the floor in the living room, much as Luke suspected it might be. He barely looked at it.

“All clear?” he said to the SWAT leader. The guy glared at Luke just a little bit. There had been a brief argument when Luke commandeered this team. These guys were NYPD. They weren’t chess pieces for the feds to move around on a whim. That’s what they wanted Luke to know. Luke was fine with that, but a terrorist attack was hardly one man’s whim.

“All clear,” the team leader said. “That’s probably your subject right there.”

“Thank you,” Luke said.

The guy shrugged and looked away.

Ed kneeled by the body. He carried a fingerprint scanner with him. He took prints from three of the fingers.

“What do you think, Ed?”

He shrugged. “I preloaded Ken Bryant’s prints from the police database on here. We should know if we have a match in a few seconds. Meanwhile, you’ve got obvious ligature marks and swelling. The body is still somewhat warm. Rigor mortis has set in, but is not complete. The fingers are turning blue. I’d say he died the same way as the security guards at the hospital, of strangulation, roughly eight to twelve hours ago.”

He looked up at Luke. There was a glint in his eyes. “If you want to take his pants down for me, I can get a rectal temperature reading, and narrow the time a little better.”

Luke smiled and shook his head. “No thanks. Eight to twelve hours is fine. Just tell me: is it him?”

Ed glanced at his scanner. “Bryant? Yeah. It’s him.”

Luke pulled his phone and dialed Trudy. On the other end, her phone rang. Once, twice, three times. Luke glanced around at the dreary bleakness of the apartment. The living room furniture was old, with ripped upholstery, and stuffing coming out of the arms of the sofa. A threadbare rug was splayed on the floor, and empty takeout boxes and plastic utensils were strewn across the table. Heavy black curtains were tacked over the windows.

Trudy’s voice came on, alert, almost musical. “Luke,” she said. “What’s it been? Half an hour?”

“I want to talk about the missing janitor.”

“Ken Bryant,” she said.

“Right. He’s not missing anymore. Newsam and I are at his apartment. We have a positive ID on him. He died about eight to twelve hours ago. Strangled, like the guards.”

“Okay,” she said.

“I want you to access his bank accounts. He probably had direct deposit from his job at the hospital. Start with that one and work your way out from there.”

“Um, I’m going to need a warrant for that.”

Luke paused. He understood her hesitancy. Trudy was a good officer. She was also young and ambitious. Breaking the rules had derailed many a promising career. But not always. Sometimes breaking the rules led to fast-track promotions. It all depended on which rules you broke, and what happened as a result.

“You have Swann there with you?” he said.

“Yes.”

“Then you don’t need a warrant.”

She didn’t answer.

“Trudy?”

“I’m here.”

“We don’t have time to execute a warrant. There are lives at stake.”

“Is Bryant a suspect in this case?”

“He is a person of interest. Anyway, he’s dead. We are hardly violating his rights.”

“Am I right that this is an order from you, Luke?”

“This is a direct order,” he said. “This is my responsibility. If you want to take it that far, this is me telling you that your job depends on this. You do what I say, or I will initiate disciplinary proceedings. Is that understood?”

She sounded petulant, almost like a child. “Fine.”

“Good. When you access his account, look for anything out of the ordinary. Money that doesn’t belong there. Large deposits or large withdrawals. Wire transfers. If he has a savings account or investments linked, take a look at those. We’re talking about an ex-con with a custodial job. He shouldn’t have that much money. If he does, I want to know where it came from.”

“Okay, Luke.”

He hesitated. “How are we doing on license plates?”

“We are going as fast as we can,” she said. “We accessed overnight video footage from cameras at Fifth Avenue and 96^th Street, as well as Fifth Avenue and 94^th Street, and a few others around the neighborhood. We are tracking a 198 vehicles, 46 of which are high priority. I should have an initial report from headquarters in about fifteen minutes.”

Luke glanced at his watch. Time was getting tight. “Okay. Good work. We’ll be down there as soon as we can.”

“Luke?”

“Yes.”

“The story is all over the news. They have three live feeds on the big board here right now. They’re all leading with it.”

He nodded. “I figured.”

She went on. “The mayor has scheduled an announcement for 6 a.m. It sounds like he’s going to tell everyone to stay home today.”

“Everyone?”

“He wants all nonessential personnel to stay out of Manhattan. All office workers. All cleaning workers and store clerks. All school children and teachers. He is going to suggest that five million people take the day off.”

Luke put his hand to his mouth. He took a breath. “That should do a lot for morale,” he said. “When everyone in New York stays home, the terrorists just might hit Philadelphia.”
