Gibbs and his team were standing in observation watching an anxious-looking Marie Davis. She had been rather frustrated when the agents arrived at her house again, this time to bring her down to headquarters, but she hadn't tried resisting. The team was now observing her, trying to see how she was reacting as she sat alone, waiting to see what was in store for her.

"Marie Davis," Tony said as he entered the interrogation room, closing the door behind him and taking a seat across from the suspect.

"Have there been new developments in my husband's case?" Marie asked.

"You could say that," Tony shrugged, holding back a smirk. "Mrs. Davis, I'm going to give you a chance to tell me anything at all that you may have forgotten or neglected to tell me before that may pertain to your husband's death. I highly suggest you take advantage of this opportunity."

"I..." Marie sat with her mouth gaping open, her eyes darting back and forth as she tried to think of something to say. "I don't know what you want from me. I had nothing to do with anything, and I've already told you everything I know."

"Really?" Tony asked. Marie nodded. "Well, you blew your chance."

"I don't-"

"You remember when we asked you about Shawn Klein?" Tony began.

"Yes," Marie replied. "I also remember telling you that I've never met him...and I haven't." Tony could see the frustration in her eyes which were, suspiciously, not red at all and showed no signs of recent crying or grieving.

"Well, you may very well have never met him, but you do know his wife," Tony said. Marie furrowed her brow, clearly confused.

"And you know that how?" she asked.

"Why don't you tell me about your relationship with Crystal Klein first," Tony continued, ignoring Marie's question.

"We're...friends," she replied slowly. Tony nodded, writing her response, and hiding his confusion about the cautiousness of her answer.

"You're friends with Crystal Klein?" he repeated. Marie nodded her head.

"Yes," she replied. "Why is this relevant?"

"Because if you were really friends with Crystal Klein, you'd have more of a problem with the fact that she was having an affair with your husband," Tony replied.

"This again?" Marie nearly exclaimed, not trying to hide her annoyance. "I told you John wasn't cheating on me."

"Yes, but Crystal Klein told us otherwise," Tony countered. There was a long pause from Marie, and the interrogation room was silent.

"What?" she asked quietly.

"Mrs. Klein admitted to having sex with your husband," Tony explained. "She then eluded to the fact that it became an affair."

"I don't believe you," Marie insisted, shaking her head.

"Of course you do," Tony said. "You just want to try not to."

"You're ridiculous," Marie spat, folding her arms across her chest. "My husband was a marine. He served this country and put his life on the line so that the likes of you could be free, and you want to thank him by pinning adultery on him?"

"No," Tony replied. "I want to thank him by doing my job and solving his murder. Bringing his murderer to justice."

"Then why don't you focus on that instead of trying to convince me of an affair that wasn't happening?" Marie asked sternly.

"All right," Tony said calmly, a smirk crossing his face. "You want me to solve your husband's murder? I'll do you one better. I'll tell you what happened right now."

"You already know?" Marie asked, her eyes widening. She watched as Tony opened a folder he had brought in with him and pulled out a piece of paper, laying it in front of her.

"This is Crystal Klein's phone record," he explained. "And this is your phone number." He indicated to the many phone calls that Marie Davis had made to Crystal Klein over the past several weeks.

"This is irrelevant," Marie said, shaking her head. "I thought you were telling me how my husband was murdered."

"I don't have to," Tony said. "You already know."

"What are you saying?" Marie demanded.

"I'm not the first person you've heard the news about Crystal's affair with your husband from," Tony explained. "You found out about it and were pissed. All these phone calls from you to Crystal were to harass her and try to make her stay away from your husband."

"No," Marie insisted, adamantly shaking her head.

"You were harassing her, and then, blinded by hurt and anger, you killed your husband for being unfaithful," Tony concluded.

"That's not true!" Marie exclaimed. "They weren't having an affair. I wasn't harassing her. Those phone calls were because we're friends; we talk on the phone!"

"I don't call my friends nearly that often," Tony said, gesturing toward the phone record.

"That doesn't make it harassment," Marie said. "And it doesn't make me a murderer." There was another long pause as Tony stared into the eyes of this woman. The frustration was gone from her gaze, and it had been replaced with pure hatred. Her words were spoken with venom in them, and Tony knew he was close to finding out the truth.

"If you have nothing to hide, you won't mind if we search your house," he said. Marie let out a long breath but didn't remove her eyes from Tony's.

"You're not going in my house without a warrant," she hissed.

"That, Mrs. Davis, will be arranged," Tony smiled before standing from the table and exiting the interrogation room.

"That was getting rather heated," Ziva said as Tony entered the observation room.

"I know," he agreed. "She's hiding something still. There's gotta be something at that house she doesn't want us to find."

"Then find it," Gibbs said. Tony nodded, and he and Ziva left, ready to solve this case as soon as possible.
