Henderson sat at the table in the interrogation room, alternating twirling a pencil between his fingers and tapping it on the table all the while being observed through the two-way mirror by Grissom and Sara.

"Appears a bit nervous doesn't he?" questioned Grissom as he turned to face Sara.

"Oh yea, more than a bit nervous," answered Sara with a tone in her voice that suggested she couldn't wait to question Henderson.

"Did he bring the uniform he was wearing that night?" Grissom waited for an answer. "Sara, the uniform?" He reached out to touch her.

"What?" Startled, Sara dropped her gaze to the floor. "Sorry Grissom, it's just that..."

"I know," he interrupted. "It's okay. The uniform?" he asked again.

"Catherine's testing it now." Sara impatiently checked her watch. "Where the hell is Brass?"

"Right here." Brass walked through door behind them with a man neither Gil nor Sara had seen before.

"Sara Sidle, Gil Grissom," he introduced them. "Meet Phil Mauer."

Sara extended her hand and smiled. "Hi..., Phil Mauer?" She shook her head not knowing the reason for his visit.

"Phil Mauer," Grissom crossed his arms and began in a way that said he knew exactly who Phil Mauer was. "He's also a deputy and assigned to the same sector as Henderson." Grissom directed his next question directly to Mauer. "You placed a call for assistance at 12:30 A.M. is that correct?"

"Yea, I responded to a disturbance at a bar and radioed for assistance upon my arrival. Henderson was dispatched to back me up."

"What time was it when he arrived?" Grissom asked.

"Well," Mauer continued as leaned back against the wall. "That's the interesting part. In our sector, even if you're all the way on the other side, it shouldn't take more than fifteen minutes to respond to any call."

"And in the case of an officer needing assistance...., it should take less than that," Brass added.

"You got that right," Mauer nodded. "After waiting twenty minutes, I called dispatch again. It took him twenty-five minutes to get there."

"Did he give any reason for taking so long?" Sara asked looking at both Grissom and Brass.

"He said he had a tire problem, but he never called it in. Later I checked with one of the mechanics at the garage, he never reported anything to them either."

Sara turned back to look at Henderson, now spinning the pencil. "Do you have anything else to add?"

"One thing I remember, when he finally showed up, I could smell his brakes."

"Smell his brakes?" Sara turned back towards Mauer.

"Yea," Mauer shrugged his shoulders and continued. "He heated his brakes up so much I could smell them."

"So if he was driving fast enough that he was having to use his brakes that hard, why did it take him twenty-five minutes to get there?" Grissom asked, but this was a question he didn't need an answer to. "Thank you Mr. Mauer for coming in, we appreciate it."

"Hey no problem." Mauer shook hands with Brass and Grissom. "If Henderson did what I've heard, he needs to be locked up. He's a black eye for the whole department." He turned and headed back towards the exit.

"Shall we question Henderson now?" Sara was almost chomping at the bit to get her chance at him.

"After you," Grissom opened the door to the interrogation room and followed her and Brass in.

Henderson looked up nervously as they entered.

"Hi Brad," Sara smiled, hoping Henderson would relax and not realize how much trouble he was in.

"Sara?" He looked up with an expression that said he didn't understand what was happening. "I already told you everything I know, why am I here?"

Sara looked to Grissom, he nodded with a look that said he was letting her take the lead on this. She sat down across from Henderson while Grissom and Brass took up positions off to the side.

"Brad, tell us about your relationship with Debra."

"My relationship?" he sounded surprised. "I quess you know I had an affair with her then."

"We know," Sara continued. "Tell us about it."

"Do you have a family Sara?" His question caught her off quard.

"No."

He looked down at the table, "I know it's no excuse, but my wife gave birth to twins nine months ago. We already had a toddler, it was more than I could handle at the time."

"You're right, it's no excuse," Sara said not hiding her disgust with him very well.

"I know, I almost lost the most important thing in my life. But I was lucky." He looked Sara in the eyes.

"Lucky?"

"My wife took me back, she hasn't forgiven me yet, but we're working on it."

"How long did you see Debra?"

"About two months. She understood when we broke up, that's why we stayed friends."

"Brad, there are several descrepancies that we need to ask you about? she began.

"Descrepancies?" He looked from Sara to Grissom and Brass and back to Sara. "I don't understand."

"Debra Farmer died at midnight. You reported available at 11:30 P.M. after responding to a call for a possible prowler. Your next call was at 12:30 A.M. and it took you over twenty-five minutes to arrive. Can you account for your whereabouts during this time?"

Henderson's expression immediately changed to one of shock. "Wait a minute, you think I killed Debra don't you?" He stared at Sara, but she showed no emotion on her face. He quickly looked at Brass. "I didn't do it. You have to believe me. I didn't kill her."

"Brad, before we go any further, do you want an attorney present?"

"An attorney, you really think I did it don't you? Don't you?" His voice was beginning to rise.

"Brad, calm down." Sara was trying her best to be reassuring. "Do you want an attorney present?"

"No, no I'm fine. I don't have anything to worry about. After all I didn't do it."

"Can you tell us why it took you twenty-five minutes to respond to the call?" Sara returned to her line of questioning.

"I had a tire I thought was going flat."

"You didn't report it to the garage after your shift."

"I took care of it myself, I didn't think it was necessary."

There was a knock on the door as it opened. "Gil, Brass," Catherine stuck her head in. "I have something I think you should all see."

Sara excused herself from the table and joined them in the hallway.

"I've got the test results on the uniform Henderson wore the night of the fire." She handed the clipboard to Grissom.

Grissom flipped through the papers. "Interesting." He raised an eyebrow and handed them to Sara.

"This isn't possible," she said as she checked the results. "Nothing?" she looked at Catherine. "You didn't find anything?"

"Clean. No hair, blood, fibers. No trace of gas. Not a thing."

"Then he lied about trying to save her," Sara sighed. "If he crawled down the hallway like he said he did......" Sara didn't finish.

"I think we have enough," Brass said and went back in the interrogation room. "Brad Henderson, you're under arrest for murder and arson in the death of Debra Farmer, you have the right to remain silent...." He continued, but Henderson could no longer hear him. He stared in disbelief at the two-way mirror on the wall, knowing Sara and Grissom were on the other side.
