“Well, it turns out that he’s had enough field training to know that when you open the roof door on a mass of the infected, you should stop and turn around.”

My toe caught on the lip of the stair I was stepping over, sending me tumbling forward. I grabbed the railing, banging my elbow in the process. “What?!” I barked, in almost perfect unison with George.

“There’s a mob up there. Kelly says twenty, Alaric says eleven, I’d say the real number is somewhere in the middle.” Dave paused. “He got a positive ID on Mrs. Hagar before he slammed and barred the door. The rest didn’t come from this building.”

“Meaning what?” I asked, picking myself up and resuming the trek toward the third floor.

Meaning this “outbreak” is somebody’s idea of cleaning house.

“Somebody had to put them there,” said Dave, unknowingly supporting George’s statement. “There’s no way our building is generating spontaneous zombies.”

Swearing steadily now, I took the last of the steps in four long strides, kicking open the door to the apartment. Kelly jumped, staggering back against Alaric. She was as white as a sheet. Alaric’s complexion was too dark to let him pull the same trick; he was settling for turning a jaundiced yellow-tan. Dave didn’t even turn around. He just kept typing, hands moving across his conjoined keyboards like he was conducting the world’s biggest orchestra.

“Prep for evac,” I snapped. “We’re out of here as soon as Becks gets back.”

“Why don’t we go meet her?” demanded Kelly, a thin edge of hysteria slicing through her voice. “Why do we have to wait up here? There’s a live outbreak on the roof! Those people, they’re infected!” The hysterical undertones were getting louder, like she wasn’t sure we understood that this was supposed to be a big deal

Deep breaths, counseled George. Count to ten if you have to.

I actually had to count to thirteen before I felt calm enough to speak without shouting. “We’re aware of outbreak protocol, Dr. Connolly,” I said. My tone was cold enough to make Dave glance away from his screen and shake his head before going back to work. “Rebecca is currently confirming whether it’s safe for us to proceed, or whether we need to find an alternate route. The rooftop door is locked, and the front of the building is sealed. We’re safer sitting here than we would be rushing blindly toward what we think might be an exit.”

“The building design makes that tunnel a perfect kill-chute,” added Dave. “If there’s anything down there, Becks is probably clearing it out before she reports back. If not, she’s confirming that we can get out of the garage without dying.”

“Actually, she’s right behind you.”
