I wore the air workers’ plain white jumper, tucking my hair under the bump cap. The air filters and scrubbers were cleaned on a regular schedule. Between shifts only a few scrubs lingered to keep an eye on the equipment. I strode to a two-meter-high rectangular box as if I had an urgent purpose. A large air shaft entered the side of the container and another exited the other end. No one questioned me as I climbed the ladder to the top of the container and the access ports that allowed the scrubs to remove the filters, clean them and return them.

Lowering myself, I squeezed through the rows of filters. Soft and made of a cloth mesh, the bags trapped the dust particles in the air. A strong current pushed through the chamber. I tried hard not to damage the filters as I swam through them. On the intake side of the container, I climbed into the oversized trunk air shaft and followed it up to one of its branches—air shaft seventy-two.

Working my way through air filters and wire security screens, I reached the Pop Cops headquarters and placed a microphone near a vent.

I couldn’t resist making a side trip to the holding cells. Risky, yes, but there could be a way to rescue Cog, I rationalized. When the covers on the vents turned into solid bars, I knew I had reached my destination. Slowing, I moved with care. Only a slight whisper of fabric sounded.

Harsh daylight streamed from below. Armed Pop Cops occupied the room. Desks and chairs with handcuffs littered the space, appearing to be a processing area for the inmates. Double doors festooned with locks filled the back wall.

Farther along the shaft the light changed into a muted yellow. The smells of sweat, blood and fear created an acidic stew. Taking shallow breaths, I peered into the dank cells. Black bars caged tiny areas only big enough for a bed and toilet. Although, calling the metal slab a bed was being generous. Three cells lined each side of the room with a short corridor between them. Cog was the sole occupant.

His bulk filled the slab and his feet dangled off the end. In the sickly half light the raw and bleeding bruises on his face resembled rotten meat. His eyes were swollen shut and his breath rattled. I rested my forehead on the duct for a moment, trying to see past the fog of horror and guilt clouding my vision. Pressure built inside my skull and chest as if I would explode. I fought to muffle my sobs.

My fault. Retrieving those disks had been a lark. I didn’t believe in Gateway, didn’t care about the prophet. One mistake, letting the cover slip through my fingers, and Cog…I wanted to shy away from the vision, but I forced myself to face the image of Chomper crushing and pulping Cogon’s lifeless body, and to hear the sound of splintering bones and the wet smack of bodily fluids. I let the consequence of my actions burn into my mind.
