Then a door flew open, and Jorge and Benny bolted out. They charged into the trio, knocking Aimee to the floor before leaping onto the sofas, hands clasped over their ears, each boy screeching louder than the alarm itself.

“You,” Karen ordered Greg. “Round up Benny and Jorge. And you,” she glanced at me, “you’ll take-”

“Evan,” Greg interrupted. “The new kid. We gave him a double dose of Ativan just two hours ago. Kid’s zonked out of his head.”

“All right.” Karen marked Evan’s name, turned back to me. “You get Evan. You”-she pointed at Greg-“you’re still on monkey duty.”

Greg headed for the leaping Benny and Jorge. I raced down the hall.

I passed by two open doors, small faces with large eyes peering out at me. I wanted to grab each child, carry them personally to safety. Not gonna work. Had to stick to the plan.

“Single file, into the hall. Ed will come get you,” I told them, keeping on mission.

The smoke was thicker at the end of the hall, making my eyes sting. I started coughing, holding one hand over my mouth as I entered Evan’s room. Despite the noise, the boy was passed out cold, curled up in a ball, with a blanket over his head.

I grabbed his shoulder, shook him, hard. Nothing.

The smoke made me cough again. I yanked off the blanket, lightly slapping Evan’s cheeks. Still nothing.

More smoke. My eyes burning. My chest, getting tight.

Fuck it. I dug my hand under his shoulders and propped him into a sitting position. Evan’s head rolled back against my arm, his mouth slack-jawed. I braced my legs, counted to three, then heaved him up, like an overgrown baby.

I staggered back, gritting my teeth. Right before I toppled, I found my balance, getting my legs beneath me as I shifted Evan’s deadweight in my arms. The boy wasn’t too heavy but a long, awkward shape, with his scrawny limbs flopping about.

Coughing harder, I put one arm around Evan’s shoulders, the other around his hips, then stumbled into the hall.

The hall was growing darker, harder to see, harder to breathe.

I tripped, almost going down. At the last instant, I caught Evan by the waist of his pajamas, and forged ahead. Vacant rooms loomed on either side of me. One, two, three, four, five.

The team had done their job. I passed the common area and arrived in front of Karen.

“Evan,” she triumphantly checked off. “That’s a wrap. Into the stairwell, Danielle. I’ll bring up the rear.”

The smoke alarm was still shrieking. Karen held open the door for me. The lobby area was clear of smoke, allowing me to draw a deeper breath as I made my way toward the emergency exit. Evan felt heavier now. My arms burned. Lower back, too. I needed to hit the gym. Lift weights. Something.

I got the fire door open. One flight at a time. Help awaited at the bottom of the stairs.

I rounded the seventh-floor landing with my shoulder leaning against the wall for support. Above me, I heard the fire door clang shut: Karen, beginning her own descent.

Eight-year-olds are heavy. Seventh floor down. Then the sixth. One foot, then the other.

I made it to the third-floor landing, paused to catch my breath, then the door burst open. I blinked against the sudden infusion of light.

Andrew Lightfoot strode into the stairwell.

“Perfect,” he said. “And you brought Evan. Makes my life even easier.”

“Andrew? Shouldn’t you be recovering-”

I never finished. Andrew stepped forward, two slender black wires flew through the air, and I felt a zap wallop my chest.

Evan dropped to the floor. I was right behind him.

CHAPTER THIRTY-EIGHT

By the time the fire engines roared up to the front entrance of the Kirkland Medical Center, D.D. and Alex had already spent fifteen minutes fighting their way through the growing throng of overworked staff and confused patients. There were nurses directing wheelchairs with attached oxygen tanks, interns guiding hospital beds bearing patients, and security guards trying to keep the exits clear. Glass doors opened. People poured out. Firefighters rushed in. Alarms continued to shriek.

The whole episode had D.D. troubled. First Andrew Lightfoot was poisoned. Then, according to one frazzled nurse, he hopped off the gurney and walked out of the emergency room. An hour later, the smoke alarms sounded, and now the entire hospital was being evacuated.

What were the odds?

Standing in the parking lot, peering up at the seven-story building with her hands clasped over her ears, D.D. couldn’t make out any sign of flames. Smoke, however, drifted up from rooftop vents. A fire in the walls? Electrical issues?

She turned to Alex. “Real or fake?” she asked him above the din.

“Smoke seems real enough.”

“And where there’s smoke…” Screw it, it felt wrong. D.D. went in search of a fireman.

First one she spotted was standing next to the fire engine, chattering on his walkie-talkie. He didn’t look happy to be interrupted by a civilian, but responded to her detective’s shield.

“What’s the situation?” she asked, shouting to be heard.

“Reports of smoke on the eighth floor. Seems to be coming from the ventilation system.”

“Fire?” she asked.

“No heat,” the fireman said with a frown. “Generally means we got a sleeper fire somewhere in the walls. Gotta watch how we vent, or we can create one helluva backdraft. Crew is climbing all over the building now, still can’t find the source.”

“Mechanical room?”

“Working on accessing.”

“Thanks. Keep us posted.”

D.D. turned away from the fireman, went back to Alex. “My Spidey-sense is tingly,” she muttered.

“Mine, too.”

“Cops do know woo-woo. Fucking Lightfoot. It’s about the psych ward. He rigged something, did something to force the evacuation. Question is, why, and did he get what he wanted?”

“Where are the kids?” Alex asked, peering around the crowded parking lot. Bedridden patients, standing patients, and wheelchair-bound patients. No kids.

A nurse raced by. D.D. grabbed the man’s arm, forcing him to pause.

“Hey, Boston PD!” she yelled. “I need to know: the kids on the eighth-floor assessment unit. Where do they exit for one of these drills?”

The nurse blinked at D.D., obviously caught between multiple tasks. Then he pointed to the side of the massive building, his words rushed as he bolted for his next patient. “They evacuate over there, the playground.” He raced off.

She and Alex hustled their way through the dense crowd to the other side of the building.

“It’s Lightfoot,” D.D. muttered, hands back over her ears. “I know it. But why him? And how?”

“We need his name,” Alex said. “That’s the problem. We don’t even know who the hell he is.”

“Someone does.”

“Gym Coach Greg,” Alex said.

“Actually, I was thinking Danielle.”

When D.D. and Alex made it around the building to a grassy clearing, they discovered fourteen huddled children and seven frayed adults. The noise from the fire alarms was quieter here. The noise from the howling children louder. D.D. headed for the nurse manager, Karen, but Greg got to them first.

“Where’s Danielle?” he demanded, his face tight.

“Funny, that’s what we were going to ask you.”

“Karen sent her to get Evan. I haven’t seen her since.”

They turned to Karen, who was already frowning. “But she got Evan. I checked them off; they headed down the stairwell right before me.”

“You saw them enter the stairwell?” D.D. clarified.

“Yes. I grabbed a last few things, then headed down. I could hear them in front of me. At least, I assumed it was them.”

“Danielle and a kid?”

“The Oliver boy. Evan. He was admitted earlier today-”

“Wait.” D.D. whirled back to Greg. “This is the Evan you know? You worked for his mom, who was stabbed this morning?”
