“I meant temperature. Hot or cold?”

“Oh. The foam’s room temperature, but the few places where there isn’t foam, it’s ice-cold.”

He grinned. “Have you pressed your ear to it?”

I admitted I tried to listen for sounds from the other side. “I heard nothing besides the Hum.” Produced by the machinery, the Hum was a constant background noise. It seemed like Inside’s breath, and most scrubs no longer noticed the Hum.

“Too bad.”

Eventually the lift passed with a chilly blast of air. We scrambled over the barrier, but landed with care on the lift’s roof. I pressed the override button for the fourth level. I didn’t think it would concern the occupants too much. The Pop Cops always complained about the lift’s odd quirks.

Voices reached us from below, but they were indistinguishable. I put a finger to my lips as Logan’s eyes flew wide when the lift ascended. It moved fast and in a handful of seconds we reached the top. I waved Logan on. In his haste, he fell with a grunt and a bang over the barrier into the fourth-level Gap.

We halted, listening for sounds of discovery. Nothing but the hiss of the lift’s door shutting. I grabbed the edge of the barrier and pulled until my hips rested on it. The lift dropped away, leaving my legs dangling. Logan scooted back and I joined him on solid ground.

After taking a moment to recover, I led him through the maze of pipes and ductwork to the hatch. Finding the hatches the first time had been difficult. I’d spent hours exploring each Gap for the near-invisible hatch. Grinning, I remembered how disappointed I had been when I found the last one. The search had provided me with a challenge unlike my prior week-to-week pointless existence.

When we reached it, I whispered in Logan’s ear, “No talking, no sounds at all from now on. Got it?”

“Yes.”

The fourth-level hatch opened into air duct number fifteen, which crossed over the giant water storage tanks in Sector H4 before cutting through the uppers’ rooms in Sector E4. I counted the suites, but then realized I didn’t need to as I felt Riley’s impatience through his air vent before seeing his worried face staring at the ceiling.

Under the vent, he had a stepladder set up on a table. Removing the cover, I slid my legs out. “Feet first,” I said to Logan before lowering myself down.

Riley hurried to put the ladder away after Logan had reached the floor. We stood in the middle of a small living area. Couch, two chairs and one low table decorated the room. The two men eyed each other.

“It’s safer if I don’t introduce you,” I said into the uncomfortable silence.

“He’s a scrub,” Riley said.

“So?” I shot back.

“He doesn’t have a port and can’t access the computer network.”

Logan smirked. “Don’t need a port. Where’s your terminal?”

Riley failed to look reassured but opened a metal curtain just like the one in Broken Man’s hideout. He pulled over one of the chairs and gestured for Logan to take a seat.
