Wheeler had replaced the monorail’s dog-brain remote control with the one he’d rebuilt at the suite. As a result of the new dog-brain interface—equipped with masking utilities courtesy of Archangel so the replacement wouldn’t be detected by the main transport CPU downtown—the dwarf rigger not only had access to the monorail’s controls, but the security cameras as well. The other members of the team could see everything that was going on in all the cars.
