I walked through the reception hall, between the staircases and through a set of double doors. It looked as if nobody had been here in years, decades even, everything covered in a layer of dust. The paintings on the walls were all of military leaders through the centuries, their medals muted by grime, their eyes following me. A massive chandelier swung from the ceiling as if something had just disturbed it, but mine were the only footprints on the filthy floor. A long corridor stretched out from the lobby, doors on either side standing open. I peered into a couple of the rooms but they were mostly empty, a few containing just scraps of old machinery and the occasional desk. One was packed with bunk beds, the same kind as had been used in Furnace, the sheets fluttering in the breeze from a broken window. I thought about going back to the front door, telling Zee, Simon and Lucy that there was another way in. But what was the point? If Furnace wanted me here alone then that’s what was going to happen.
