"Get in here!"
Curt moved slowly forward. Brown closed the door behind him and motioned toward a closed door at the other end of a short hall. They opened it and stepped into a dimly lighted room.
Curt's eyes slowly adjusted and he saw what seemed to be a laboratory. It was so packed with equipment that there was scarcely room for the group of twelve or fifteen men jammed closely about some object with their backs to Curt and Brown.
Brown shambled forward like an agitated skeleton, breaking the circle. Then Curt saw that the object of the men's attention was a large cathode ray screen occupied by a single green line. There was a pip on it rising sharply near one side of the two-foot tube. The pip moved almost imperceptibly toward a vertical red marker over the face of the screen. The men stared as if hypnotized by it.
