The next day at work, each team member was sitting at their respective desk trying to piece the different aspects of the case together. The only person missing was Gibbs who was presumably refilling his coffee. McGee sat at his desk, typing away, as Tony and Ziva each looked through paperwork of their own. The complexity of the case was growing; everyone they interviewed had something different to say, and a lot of it wasn't lining up. They certainly didn't appear close to locking up John Davis' killer.

Outside, the sun was shining brightly in the clear, blue sky. Ziva glanced out the window and wished she was with Tony and their children, in the park enjoying the nice day as a family. Instead, she sat at her desk hoping to make sense of the case that had been troubling them for several days. She sighed, trying to make herself focus on finding the killer. The sooner this was solved, the sooner she could have time back for her children.

Across from his wife, Tony had similar thoughts. He wanted the case to be over as well. However, he couldn't stop thinking that they had previously let the killer go free. He felt so strongly that Marie Davis was involved, but for some reason, he and Gibbs were on different pages. Ordinarily, Tony would go along with whatever his boss said because Gibbs' gut feeling tended to be correct. This time, though, it was different. Tony and Gibbs each had their own gut feelings, and they strongly differed from one another. Finally, Tony laid the paperwork down and opened his mouth to speak. Ziva and McGee's attention was drawn to him, and they waited for him to say what was on his mind.

"Yes?" McGee asked, curious about the pensive look on his coworker's face.

"It's gotta be Marie," Tony stated. Ziva and McGee waited for an explanation, but Tony said nothing further, though they could tell his mind was racing.

"Why?" Ziva asked.

"If her husband had been having this affair, there's no way Marie wouldn't have know," he began. "From the sounds of it, Crystal wasn't trying too hard to keep it a secret. Marie had to have known and killed her husband for being unfaithful."

"I don't know," McGee said. "Marie has been seeming pretty convincing. Maybe she really didn't know."

"Or maybe she just wouldn't let herself believe it, so she convinced herself it wasn't true," Ziva added.

"The bloody knife was at their house," Tony continued.

"Anyone could have left it there," McGee countered.

"But have you paid attention to her interrogations?" Tony asked.

"Yes..." McGee said slowly, a confused expression on his face. "She is very adamant about the fact that she was not involved in the killing of her husband."

"But she's not grieving properly," Tony said.

"What exactly is the proper way to grieve when your husband was killed?" Ziva asked, cocking her head to the right.

"She likes to act like she's crying, but there are never any tears," Tony pointed out. "Think about it. It's an act."

"Well then she's a good actress," McGee scoffed.

"It could happen," Tony defended himself. "It's an act. She wants us to think she's upset and grieving so that we'll believe she's innocent. Then she sends us on wild goose chases, like her neighbor who supposedly had some dispute with her husband. Meanwhile, she's probably sitting back enjoying the fact that we're running around questioning innocent people while she's getting off the hook."

"Don't you think that's kind of a stretch?" McGee asked.

"No, I don't," Tony replied. "I think that's exactly what's going on."

"Well I think Gibbs would believe Crystal killed Davis before Marie would," McGee said.

"And what do you believe?" Tony asked. McGee took a moment to respond.

"I think Crystal is more likely," he replied. Tony shook his head.

"Why?" he asked, slightly annoyed.

"She admitted that she and Davis were having an affair, Tony," McGee said. "If they were hiding it from Crystal's husband, they were hiding from Marie too. Maybe the affair turned into more for Crystal and she developed feelings for him. When Davis wouldn't leave Marie, Crystal killed him."

"Good theory, McGee," Gibbs said, rounding the corner.

"Um, thank you, boss," McGee replied. Tony clenched his teeth, knowing Gibbs hadn't heard his own theory as to why it was Marie who was guilty.

"Tony, Ziva, get her back in here. I'm ready to finish this damn thing," Gibbs ordered. Tony and Ziva obeyed and exited the squad room to bring in Crystal Klein again.

"I think you're all wrong," Tony said bluntly in the car on the way to the Kleins' house.

"I know you do," Ziva sighed. "But this is what Gibbs thinks, and we cannot-"

"Go against what he says?" Tony finished for her. "Well this time I think he's got it wrong."

"You have to admit that it is very possible for Crystal to be involved," Ziva said. Tony thought for a moment before Ziva continued. "Especially if she and Marie were friends."

"Fine," Tony relented. "Maybe Crystal was involved...But she certainly wasn't alone. Marie had a part in it." Ziva sighed; Tony was being very persistent.

"I am sure that if Marie was involved, we will find out soon," Ziva said. "She cannot get away with it forever."

"She can if we keep letting her," Tony muttered. Ziva chose to end the conversation as they pulled up in front of the Kleins' house.

Inside, Crystal was sitting in the living room when she saw a dark car stop in front of her house. She stood from the couch and walked to the window and watched as Tony and Ziva got out of the car and headed toward the front door. Quickly, Crystal pulled out her cell phone and went to her last text message conversation. "They're here," she typed quickly and sent before she heard the knock at the door. After taking a deep breath and clearing her text messages, she answered the door.

"Hello," Crystal said with a puzzled look on her face. "Can I do something for you?"

"We're going to need you to come with us," Tony replied.

"What for?" Crystal asked.

"We just have some more questions we need you to answer," Tony explained.

"Of course," Crystal smiled. "I don't have anything to hide." She closed the front door after joining Tony and Ziva on the porch and walked with them back to the car to head back to NCIS headquarters.
