But when the doors slid open, they revealed a darkened lab. The only illumination came from above and behind Carla, in the ceiling of the elevator itself. It painted Carla’s shadow in a dark puddle, just inside the large room, and only partially illuminated the large, open space that lay beyond it. Stale-smelling air wafted in through the elevator doors; it was clear that the lab’s climate-control systems weren’t working. They’d probably shut down yesterday morning when the spirit wiped the lab’s data files and scrambled the computer’s programming.
