At 3:45 am, it wasn't especially easy for Dr. Greg Livingston to drag himself out of bed and down to CSI headquarters. However, he had been implored by his past colleague, Archie Kao. With barely any time to get ready, as Archie was insistent that he hurried, he had just enough time to grab a cold cup of coffee and a compact disc labelled 'GeoTechnix: Property of Dr. Greg Livingston'. In not even the blink of an eye, he was in the car and down the street, leaving the quiet neighbourhood in peace.

Archie met Dr. Livingston in the parking lot. He was about middle-aged, thin, but well-proportioned, and had a pleasant face. Aside from looking tired, he managed to look decently presentable, his hair parted neatly at the side, stubborn curls overhanging his brow.

"Thank you for coming on such short notice," Archie insisted to his old colleague. They had taken the same computing skills course years ago together. It was then that Dr. Livingston discussed with Archie his plans for an exciting new project that would prove relevant in a time of geographical uncertainties.

"I assure you that, given the circumstances, it is quite more than alright," Dr. Livingston replied.

The two men rushed into the building to meet Grissom, who was already eagerly seated in front of the large projection of the computer in Archie's department. He had with him photographs of the car wreck miniature, which he examined still, with ever as much intensity.

When Archie and the doctor stood in the doorway, Grissom turned to them and sat forward in his chair. Weary as he was, he decided not to stand up. Dr. Livingston, a polite and sympathetic soul, understood completely.

"This is Dr. Gregory Livingston, specialist in landscape geography and seismology," Archie said.

"Thank you for your help," Grissom said, a small tremor in his voice. In the back of his mind, he felt guilty for excluding the other members of his team but he knew they would make better progress working where they were not distracted by whatever strange unnerve he might be emitting. He had considered perhaps that they would be fine. He couldn't take the chance. He was going to lose his nerve. He trusted Archie, at least, to keep to himself and stay on task. He felt a mutual sense of respect of privacy with him. It was as though through watching people for hours on end, he imagined that Archie possessed an understanding of human behaviour that would not make his own seem strange. Or maybe he just couldn't face the others.

Dr. Livingston smiled wearily, clearly not completely understanding the magnitude of the situation.

Grissom said, "Please excuse my abruptness, doctor, but one of my CSI's is trapped underneath a car in the desert somewhere remote and we have absolutely no way of finding out where she is. Archie is certain you can help and time is everything."

He nodded, having already popped the CD into the drive, bringing up the revered program. As the doctor manipulated the machine, he spoke. "GeoTechnix has allowed me to develop a program that allows us to keep track of all changes to the make-up of the land in and around Las Vegas. As we are close to some threatening fault lines, it is key to our prevention of catastrophic geophysical disasters. This program was constructed based on very accurate topographical and tectonic observations I made on a four hundred mile radius. The images that you see are a three-dimensional reconstruction of both the city and the desert combined, including various detailed physical components such as rocks, trees, fences, rivers, and the like. Using precise measurements we can track shifts in these objects and determine various other geophysical factors for our company's cause."

Archie listened patiently. The program was now completely ready to use. Grissom was blank. "And ours?"

"Show me the picture," Dr. Livingston requested. Grissom handed them to him. He examined the photographs of the miniature and began to input some data into the program. "I can track down a number of locations based on the details constructed here such as the rock patterns, landscape height, and soil composition." He typed a few more inputs and several images appeared. The results were dispairingly unrevealing. Grissom looked on with intensity.

Seeming not pleased with the program's results, Dr. Livingston said, "I fear it may not be detailed enough. It seems as though your artist has used fairly standard materials that don't provide enough of the details I require to find an exact location. I have come across nearly five hundred hits, most of which are based on useless information."

Grissom's faced tensed, his lips pouting in frustration. He was fighting to maintain his placidity in this all too public situation. "The rock formations," he said. "You recorded all of them in the desert area surrounding the city?"

"Yes, but only their locations in relation to one another. This is not based on size or shape."

"I need another solution," Grissom muttered. He went to stand and leave, but the doctor spoke up.

"You might consider speaking with my son." Grissom looked irritated but intrigued. Dr. Livingston continued. "He has his own program that he has fabricated for his own purposes. Geocaching, he calls it. I think it has more search capabilities along the lines of what you require for your case."

My case, Grissom thought to himself. This is not a case. This is Sara. This is my life. The lives of my team.

"OK," Grissom agreed. "But please hurry." The doctor and Archie both nodded.

He darted out of the room and down the hall.

"Grissom," Catherine said, suddenly appearing in front of him. "What can I do to help? What are you doing? I can do anything, but please, let me help."

Grissom considered her offer for a moment and then said decidedly, "Come with me."

"Where?"

"Hopefully to disprove the phrase 'like father, like son'."

She looked confused and then ran to catch up with him, as he was already making his way back to his office.
