What they did have was a rabbit run that exited through a trapdoor on the flat lead roof of the office. It was butted up tight against the building’s nearest neighbor, a taller structure with a series of bricks removed to make a ladder for the run. So, in event of emergency: out and up, then over and off onto the chimney road. The trapdoor was sealed from below with a heavy bolt, but after we’d spent a while listening for activity below, Triss was able to slip between the cracks and draw it for us. The door opened down into a narrow space bordered on two sides with rough lath and studs, implying plastered walls. The bricks of the neighboring building made a third wall, while a wooden panel with a latch on our side provided an exit. VoS was sensible enough not to dispute my going first. She couldn’t make herself invisible after all. The wooden panel folded in the middle like a decorative screen, so that it could be slid to one side without taking up much space either in the rabbit run or the large cupboard it backed.
