Back on the rear stairwell, we descend one level...
Another landing, again with a corridor to both sides, flanked by the 'cells' we saw on the security feed.
"Next one down," murmurs Klempner. "This should be it."
We pass under a single camera at the top of the next staircase, but it remains reassuringly off, its indicator light dark. Still, it's unsettling to have the empty black eye follow us as we descend into the dank scent of basements everywhere.
At the bottom, the same single corridor, running right and left, doors off either side. Underfoot, slab floors are slippery with damp.
There's no sound other than our own footsteps and, as I realise after a moment, my own heartbeat pulsing behind my ears. Down here, even the bass thump of the music doesn't carry.
It's cold. Not the iced night of outdoors, but a moist chill that creeps into lungs and turns breath to grey mist.
