knowledge is power

I peered at the skull. If I didn't know any better, I would think that Bob sounded . . . nervous? Was that even possible? Bob wasn't a human being. He was a spirit, a being of the Nevernever.

Bob was a records computer and personal assistant all rolled into one, provided you could keep his mind on the issue at hand.

No spirit could have that kind of knowledge without it translating into considerable power. So why was he acting so scared?
