As GS and Mark made their way down the foot of the small mountains, Mark scanned the craggy surface and GS, walking with an erring sense of direction, focused on what she could hear. Mark tried to speak with her once, but was quickly silenced with a look and an upraised palm.
GS stopped short and grabbed Mark's arm. She pointed to an opening in the rocks about ten feet above them. Mark studied the area where she was pointing and then looked back at her with a puzzled look in his eyes. In frustration, she pulled him closer to her and raised up on her tiptoes to whisper in his ear.
"There are vibrations coming from there," she hissed. "I think that might be where Nancy has her machine. I'm going to go back and get the Major. You stay here to mark the spot so we don't have to re-find it."
Without a backward glance, GS turned and ran back the way they had come. She met Lee on the way, coming towards her, a handheld device in his hand that looked like a TV remote. When he got close enough he didn't have to yell, he said, "There are stronger betavoltaic emissions coming from the area just beyond you."
"That verifies my findings," GS said. "I picked up vibrations coming from a cave. I think we should climb up there and check it out."
"I've called for back-up," he told her.
"We don't have time for that. Now that Nancy knows we are on her trail, there's no telling what she will do. We need to find that machine and we need to do it now."
"Listen, lady, you may be hot stuff in the city, but this is a military operation. Civilians need to stay out of it."
GS gave him what she hoped was a withering look, then turned her back on him and started back down the road, leaving him with only two options. He could stand there and wait for his back-up, or he could follow her. GS didn't really care which he decided to take. She was going to stop Nancy for good this time, if it was the last thing she ever did.
