A/N: So this is the real beginning of the story. It's set in Boston, NCIS in Washington will join in in chapter 2.

Chapter 1

Boston PD Homicide, Squad Room

Detective Jane Rizzoli was sitting at her desk doing paperwork when her phone rang.

"Rizzoli."

"Hey Jane," said the voice of her brother, Officer Francesco 'Frankie' Rizzoli. "We've got a dead body at the harbor."

"Okay, thanks Frankie, we'll be there in five." Jane ended the call and gave the news to her colleagues. Five minutes later, they were sitting in Jane's car and heading towards the harbor.

Boston harbor

The detectives were greeted by a large (and loud) crowd of curious people. Fortunately, all of them were staying behind the yellow crime scene tape, but they were distracting anyway.

Sergeant Detective Vince Korsak got out of the car and barked: "Okay folks, who of you found the victim?"

A boy of about twelve raised his hand. "Fine, you stay and tell us what ya know. The others, please leave, this is a crime scene."

The audience grumbled, but began to walk off. Within less than five minutes, the place was empty except for the Homicide detectives, the boy who had found the dead body, an elderly man, and Officer Frankie Rizzoli.

"Not bad, Korsak," Detective Barry Frost commented. Korsak chose to ignore this and walked over to Frankie. "So what've we got?",he asked.

"The boy says he and his grandfather found the dead woman on their way to the harbor."

"When was that and what did you plan to do at the harbor?" Korsak asked their witness.

"About half an hour ago. Grandpa wanted to watch the seagulls," the boy explained., to which Korsak nodded. "Alright. Frost, take their statements. Jane and I are gonna take a look at the victim."

"Okay." He wouldn't admit it, but Detective Frost was extremely relieved about being able to stay with their witnesses - even after two years in Homicide, he still got sick everytime he saw a corpse.

Just when Korsak and Jane ducked under the crime scene tape, a blue Toyota came driving around the corner of the street. The driver parked next to Jane's car, opened the Toyota's door and climbed out. It was none other than Dr Maura Isles, Chief Medical Examiner of Massachusetts and nicknamed Queen of the Death (only behind her back).

At the sound of her high-heels on the asphalt, Frost turned around: "Hey doc, you sure you're wearing the right shoes for this underground?"

"Good morning Detective Frost, what's wrong with my shoes?"

"The fact that our victim's over there, near the waterline," Jane cut in. "Meaning we have to cross the beach. And Maura, don't tell me you can walk through sand in those shoes."

"Jane, if it doesn't work, I'll take them off. Studies show that walking barefoot..."

"Yeah, thanks Google," Jane cut her off. "How about we take a look at our victim now?"

A few minutes later, Jane, Maura (still wearing her shoes), and Korsak were squatting next to the victim. The woman seemed to be quite young, had long blond hair and was wearing a pair of jeans and a green T-shirt. She was lying on her back, with her legs in the water and her upper body on the beach.

"Well, looks like the poor girl drowned," Korsak stated.

Maura had put on a pair of rubber gloves and was now carefully turning the body over. "A bullet hole."

Jane eyed the hole in the back of the corpse's head. "So she didn't drown, but someone shot her dead from behind and threw her into the water to get rid of her."

"That's possible Jane, but I have to do her autopsy before I can say anything about the real cause of death."

"Hey, what's that?" Korsak suddenly asked.

"What are you talking about, Detective?" Maura asked back.

"There's something round her neck."

Indeed there was a thin metal chain, half hidden beneath the victim's hair. Maura carefully pulled at it and revealed a pair of military dogtags. "Hmm, interesting," she muttered.

"What?" Jane asked.

"They're broken. If these are hers, the victim's first name is Debbie, but the part of the tags with her last name written on them is missing."

Jane rolled her eyes. "Great. A woman who died either from drowning or from being shot in the back of the head and some military dogtags with no last name on them."

"Like I said Jane, we'll know more after the autopsy."

"I damn hope so," Jane grumbled under her breath, but Maura heard it anyway: "Language."

"Sorry Maur."

Back at the PD

The dead woman was down in the morgue, waiting for her post mortem, and the facial recognition program in Homicide was running a photo of the victim's face. Just when Jane considered getting a cup of coffee, the computer beeped. Match found, it said on the screen.

Frost opened the file and a photo of a blonde woman appeared on the big screen on the wall. Next to the photo, there was some information.

"Private Debbie Paddington, aged 25, US Marine Corps," Korsak read out. "You sure this the right person? Looks more like a model than like a Marine..."

Jane glared at him. "You know, the Corps has changed a bit since you left it."

"Sorry Jane," the older detective apologized. "Speaking of the Corps, I think we should call NIS."

"NIS?" Frost echoed.

"When I was still on active duty, they investigated crimes involving Marines. And we've got a dead Marine here," Korsak explained.

"Yeah, but you were on active duty like 100 years ago..."

Now it was Korsak's turn to glare. "Okay, 50 years ago," Frost corrected himself, typing the letters 'NIS' into his computer's search engine and hitting Enter.

"And?" Jane prompted.

"Do you mean NCIS?" Frost read from his computer screen. "I'll try that one." He clicked on it.

"Now, would you please be nice and tell us about this NCIS?" Jane asked sarcastically.

"NCIS, Naval Criminal Investigative Service, till 1992 known as NIS. Korsak was right, they investigate crimes that have to do with the Navy or the Marines."

"And do they happen to have a phone number?"

"Yep. Who wants to call 'em?"
