I had a decision to make. If Crew—and any Resistance double agents—used the vacuum monorail, it stood to reason they had to be able to get into the transit station. If they could get in, but the riffraff couldn’t, they needed some way to identify themselves. I fingered the security pass in my hand. It was all very logical, but even in a human-built environment it wouldn’t be a sure thing. Or I could be right with my logic, but this card might not be for transit. Trying to get into the station using a library card would surely be unsuccessful. And probably get me noticed.
