They’d left him only for a few minutes. He said he was tired so he sat on the old dentist’s chair to have a rest. They continued to search nearby but had spread out either side of the corridor so no-one could get him. Then there was the scream. They rushed back to find the chair empty and torn and piles of dust and plaster ripped from the walls. It had taken all of 10 seconds at the most and there was no sign of him whatsoever. Now they were only four of them left. Would they ever get out of this place and back to the sunlight?
