I left the others to it and returned alone to Cell 4. I could hear the muffled cries and eerie calls
made by the others as I climbed gingerly down to the floor of Cell 4 to further explore its northern side.
After previously studying my photographs of the map I’d found, I was intent on finding the Number 9 Exhauster
which was located in the functionally named Cell 4 Annexe.
A network of stairways and catwalks lead to a doorway in the northern wall of Cell 4. A single row of grimy windows
set above looked dark; not light as I’d have expected if they lead outside. The door opened into a dark, quiet, cavernous room
which I’d never seen before. I was standing at the base of another turbine plinth, the Parsons turbine rising up into the
gloom. I’d found it.
I returned to Cell 4 to find the others but they were still in the pipe. Whilst waiting, I busied myself
with some shots of the basement offices on the south side of Cell 4: weird stairs that terminated mid floor,
empty rooms and white-boards covered in graffiti. Unfortunately there was still no sign of the almost mythical Cell 4
control room and my search was cut short by the noises of the others emerging from the air main.
