Andy noted a small black tube no more than two centimeters long between her index and central fingers. A thin wire ran from the cylinder into an open port on her wrist. He’d read about such things. She was using a tiny camera to view the scene without exposing herself. The pickup must be transmitting an image of the scene at the truck’s rear directly to her optics. Andy wondered if the transmission filled her vision, or if the pickup’s image was inset within a normal eye view. Whichever way it worked, he wished he had one so he could see what was going on.
