H eidi, for some reason, knew a great deal about custom vehicular armor. Perhaps it was a Beverly Hills thing, Hollis thought, as Aldous wound them deeper into the City, or a Ponzi scheme thing, or both. Heidi and Aldous, with whom Hollis could see Heidi was flirting, though still at a level of solid deniability, were deep in a discussion of whether or not Bigend had been wise to insist on power windows for the front set of doors, which had meant forgoing a bulletproof documentation slot on the driver’s side, through which papers might be presented without opening either the door or the window. The power windows, Heidi maintained, meant that the doors were necessarily armored to a lower standard, with Aldous firmly insisting that this was not the case.
