A/N: This isn't as good as the preface, mainly because it is just setting the scene. Thank you to all of you who reviewed! Wow! Didn't know some many people would actually read it!! Hahaha!

TWO MONTHS PREVIOUSLY...................

"The victim is a Karen Woods. 23 years of age, found by her Petty Officer Fiancée at around 9 this morning. He's on leave for a month and they were supposed to be meeting for breakfast this morning, however, she never turned up. He found her dead when he let himself in to check on her." Tony briefed Gibbs.

"My, my. You were a beautiful one weren't you my dear." Ducky said to the woman, who was lying in the middle of the lounge, her hands resting on her stomach.

"Cause of death, Duck?" Gibbs asked.

"She was shot, Jethro. Twice in the chest. They probably used a silencer as no gunshots were heard."

"There is no sign of forced entry. It looks like she let her attacker in." Ziva said. Ducky took out the liver thermometer and announced the time of death.

"11 pm to about 1 am I would say. I will have more to tell you when I get her back Jethro."

"Anyone notice something about this scene?" McGee asked. He got blank looks from everyone. "I mean it's clean. No blood spatter and look at the way the body is positioned. Eyes closed with her hands resting on her. She looks like she could be sleeping."

"Hey, good spotting McGoogle." Tony laughed. "Why is that?"

"Could be a woman." Ziva suggested. "A woman would be more likely to clear up a crime scene than a man. I mean the body is here, so why clear up the scene other than to be tidy?"

Gibbs nodded and continued to process the scene. "Work on it then."

Out of the corner of his eye, he saw Tony's hand brush against Ziva's. He also noticed that she pulled her hand back like she had been electrocuted. He smiled at the action, and remembered the time when he and Jen had been similar. However, that experience proved why rule 12 was made up, and Gibbs made a mental note to head slap DiNozzo the next chance he got.

Back at NCIS HQ, Ziva was pacing around the bullpen.

"I don't understand it! She was a shop assistant who had no enemies, why would someone kill her?"

"Maybe she pointed out the wrong aisle to someone?" Tony chipped in, in his usual cheerful manner.

"You are not helping DiNozzo. What about the Fiancée? What was his name... erm Paul Brooks?"

"Nope, checked, he was drinking with friends until about 2-3 this morning. Have CCTV bar footage to prove it. How he got up at 8 this morning for breakfast is beyond me. Especially after that many shots!"

"DiNozzo!" Ziva yelled. "You are not helping!" She sat at her desk, with her hands on her temple and her eyes closed.

"Hey. You Ok?" Tony asked as he walked over to her desk. Even though he tried to hide his concern, Ziva still heard it.

She rubbed her temples and opened her eyes. "Yes. I am sorry, I have just had little sleep."

"Oh ho ho! And why would that be Miss David?" Said Tony said suggestively.

"God! Why does it always have to be about sex with you!" Ziva said as she jumped up in disgust.

"I'm sorry, I just... I'm only teasing..." Tony murmured, disappointed with himself.

"Leave it out Tony." She snapped as she walked out of the bullpen.

"Hey, what's up with Ziva?" McGee asked as Ziva stormed past him.

"How do I know?! I'm not physic or anything McGee." Tony shouted as he too walked out.

"It's gonna be a long day." McGee whispered as he sat down

..................................................................................................................................................................

"Jenny, something does not feel right about this case." Ziva said. "Not to sound like Gibbs, but my gut is telling me something."

"Well then go with it Ziva. You should trust your gut." Jenny smiled.

"But how? I mean how do I go about it?"

"Your job." Gibbs said as he walked in.

"Jethro! " Jenny protested. "I am in a meeting!"

"I tried to tell him director, but he just ignored me." Cynthia said apologetically as she rushed in.

"I need to talk with you. Urgently." Gibbs said. Jenny stood up, but Gibbs shook his head. "Not you. Ziva."

"Me?" Ziva spluttered. "But..."

"No buts. My office. Now" He said as they walked out.

"But he doesn't have an office." Cynthia said with a puzzled look on her face.

Gibbs flicked the switch on the elevator, and it grinded to a halt.

"Now. What the hell is going on with you and DiNozzo?"Gibbs said.

"What?! That's why you dragged me here? There is nothing going on! Now I have work to do!" She yelled as she flicked the switch.

"Oh no. Not that easily." Gibbs said as he stopped the elevator again. "You and DiNozzo had better sort it, before I do!"

"Why aren't you asking Tony this?" Ziva said.

"Already did." Gibbs said simply as he started the elevator again.

"And...?" Ziva pushed on.

"You will have to ask him." Gibbs said and gave her a look that meant 'we are finished here.'

..................................................................................................................................................................

"Gibbs! Gibbs, Gibbs, Gibbs!" Abby squealed.

"Yeah what is it Abs?" He asked as he gave her the Caff-Pow.

"The bullet Ducky pulled from Karen Woods' body.... matched another bullet from an unsolved case 4 months ago!"

"What was the case then?" Gibbs asked.

"Um a Sarah Quinn. McGee is getting the case file as we speak." Abby beamed.

"Good job Abs." Gibbs whispered as he kissed her cheek.

..................................................................................................................................................................

"Sarah Quinn" Ziva announced. "Was married to Lieutenant Robert Quinn, and was shot whilst her husband was playing pool with friends. Shot to death, twice and a silencer was used. But look Gibbs, the scene is almost identical to the crime scene today. Even the furniture is set out in the same way."

"Some one moved the furniture?" Tony asked as he came up behind Ziva. She looked uncomfortable at the closeness between them, but didn't say anything.

"The targets appear to be women who are married, or dating men in the navy. I'll start checking for similar cases." Said Ziva as she ran off to her desk. She searched away and was oblivious to the fact that Tony was watching her. She was oblivious to the thoughts that were running through his head about how beautiful and talented she was. He shook his head in a vain attempt to put them out of his mind, but there was something about her that drew his eyes to her face.

"Gibbs!" Ziva called. "In the past year, there have been 5 unsolved murders of Navy wives and Girlfriends. 3 of the crime scenes match and have the same MO. Shot twice with a gun with a silencer."

"Names" Gibbs said as he stood p in the normal Gibbs fashion.

"Louise Miller, husband was on the SS Reagan at the time, Charlotte O'Meara, long term boyfriend was a home with his parents and Kelly Knowles, her new husband claims he was out with friends."

"And including our two dead women that we discovered about this morning, that brings the total up to 5. Boss, looks like we have a serial killer on the loose." Tony said gravely.

"Looks like you're going undercover David." Gibbs said, and they all turned to look at the stunned Israeli woman.
