“Shaun? Why are you breathing like that? What’s—”

“I need you to put the Doc on the line right fucking now, Alaric, or you’re getting a goddamn field promotion! Am I making myself clear, here, or do I need to get footage of the zombies trying to eat our asses?”

“I’ll get her,” said Alaric. The line beeped again, going silent.

Becks pulled up almost even with me. Sweat was adding that new-penny shine to her cheeks. “What are you doing?”

“CDC installs are all built on the same basic floor plan, right?” Another T-junction came into view ahead of us, my flashlight barely illuminating it enough to give us warning before we hit the wall.

“Right, but—”

“Doc gets us out or we’re dead, Becks.” The moaning from behind us was still getting louder, and that wall was getting closer. “Keep running!”

The ear cuff beeped, and Kelly’s hesitant voice took the place of the silence, asking, “Shaun? Is that really you?”

“In a pickle, Doc! Zombies are chasing hrough the Portland CDC, and we need out before we’re on the menu! There’s a T ahead of us—which way do we go?”

I had to give Kelly this: She recovered damn fast to what must have seemed like a totally random question. “Have you already passed a T-junction?”

“Yes! We went right!”

“You went—damn. Okay. At the T ahead, take the left, and try the third door you pass. Is the place in lockdown yet?”

“Do you mean ‘Are the lights all fucking out, and did half the doors go amber before the power failed’? Because then yeah, we’re in lockdown!” I grabbed Becks by the wrist, hauling her along as I veered left. “What kind of door?”

“Same size as the rest, but it should open when you push it.”

One door flashed by on our right, followed about six feet later by a second door, this one on the left. I slowed to keep from overshooting the third door and grabbed for the knob, all too aware of the advantage I was throwing to our opponents if Kelly was wrong. The zombies weren’t going to slow down just to keep the playing field even.

The knob turned without any resistance and the door swung inward, nearly spilling me—and by extension, Becks—into a pantry-sized room with glowing amber tubes running all along the edges of the ceiling, like supersized versions of the portable field light. I recovered my balance and stumbled fully into the room, thrusting Becks behind me before slamming the door shut. There were three old-fashioned deadbolts on the inside, the kind of things that can never go down, not even in a power failure. I slid all three of them into the closed and locked position before I’d even finished processing the impulse to do it.

“Shaun?” Kelly’s voice was strident enough to make me wince. “Where are you? Are you okay?”
