So the whole three-sided bay of the bedroom was now a completely opaque arrangement of insulated plywood walls. Presently it became even darker as Jones and Sharjeel unrolled long strips of black roofing paper and staple-gunned them over the plywood, covering the entire interior surface of the room, including the ceiling, with monochrome black, relieved only by the sporadic glint of staples. A few moments’ work with a box cutter removed a disk of tar paper from around the overhead light fixture, so that some dingy yellow light was shed into the space.
