Quess and Douglas reached the fence and quickly strung a sticky gray rope that resembled primer cord across the fence, forming roughly the shape of a large door. One end terminated in a set of wires and a small plug. As Quess severed the end that curled outward from the small roll he held, Douglas attached the wires to a small box. Without a word spoken between them, Quess stepped back and Douglas pressed a button on the box.
