"I think engineering will supply our demand for a "spiritual" life after meat death."
- Bart Kosko

Ferretscope  
  A counter-surveillance tool to detect the presence of listening devices.  

The woman took my arm and urged me down the corridor. I glanced back and saw Zeb silhouetted in in the portal, covering our rear. My guide paused and pushed me into an almost pitchblack alcove, then she took from the folds of her robes a small object which I took to be a pocket ferretscope, from the small dial that glowed faintly on its side. She ran it up and down and around, snapped it off and returned it to her person.

"Now you can talk," she said softly. "It's safe."

I felt a gentle touch at my sleeve. "Judith?" I whispered.

"Yes," she answered, so softly I could hardly hear her.
