I'm sooooo sorry about the delay. I've been busy for a while with the end of school and starting up my new jobs. To whomever continues to read the story, thank you. It means a lot to know I have so many interested readers. And I hope to have the next few chapters up in a short amount of time.

Again, I don't own NCIS or Castle nor do I own the characters. Enjoy!


Kate stood staring at the white board in front of her, wishing they had more information about the murder. But Abby had been working all night with the forensics and Lanie had started the autopsies, leaving Corporal Moore for McGee's team to examine.

"Have we heard anything from Lanie?" Kate asked and Ryan and Esposito both shook their heads. "Abby?"

McGee now shook his head. "All she said is that the sibling fingerprints are on everything. But the fourth set they found is still a mystery."

Kate turned to look at him. "And your team?"

"Should be here any minute," he replied. As he finished his sentence, a mass of sound erupted from the elevator. "And there they are."

Kate and her team watched as the remaining five members of Team Gibbs made their way across the precinct, bags and equipment in hand.

"Special Agent Gibbs," Gibbs announced as he extended his hand and Kate accepted. "Special Agent Anthony DiNozzo, Probationary Agent Ziva David, my ME, Dr. Donald Mallard and his assistant, Jimmy Palmer."

Kate smiled. "Detective Kate Beckett," she began. "Detectives Kevin Ryan and Javier Esposito, and tag-along author, Richard Castle."

"You wrote Heat Wave?" Ziva suddenly asked and every head turned to look at her, a large smile on Rick's face.

"Special Agent Gibbs, why don't I take you down to see our medical examiner, Lanie Parish," Kate said, trying to go back to the case. "Dr. Mallard, she's left Corporal Moore for you."

Ducky smiled. "Please, call me Ducky," he said. "Mr. Palmer, grab the bags please?"

Jimmy quickly grabbed the bags and followed Kate, along with Gibbs and Ducky, to the elevator. "McGee, where is Abby?" Ziva asked.

"With Lanie. She's been running ballistics and prints all night," McGee explained.

"So what do we got?" Tony asked as he and Ziva stood in front of the board.

"Three vics," Esposito began. "Corporal Gavin Moore, brother Travis and sister Grace. Each victim had two GSW's. One to the head, one to the heart, all in the exact same spots. The sister was found with a gun in her hand but Abby's ninety-nine percent positive it wasn't the one used for the murders."

Ziva looked at Esposito. "Was it fired?"

Ryan nodded and continued. "Which means we have someone running around the city with a gunshot wound?"

"Well, I'm sure he or she isn't running but that's good news," Tony said. "Have hospitals been contacted?"

McGee nodded. "Nothing yet, but they've been advised to contact us if someone shows up."

"So we have no leads?" Tony questioned.

"Just an unidentified set of prints," Rick answered. "Nothing else."

Then Esposito's phone rang. "Esposito. Right away." He closed his phone and looked at the group. "Lanie found something."

They all walked towards the elevator, Ziva noticing Tony as he looked around, smiling. "Flashing back, Tony?"

"Oh yeah," he said."These white boards and cramped quarters take me back." Ziva smiled. "Plus we never had cops in Baltimore that looked like Beckett."

Ziva hit his right arm as the elevator doors opened. Everyone boarded except Tony, who stopped when Rick held his hand out. "Sorry, not enough room. You'll have to wait."

The doors closed and Tony stood alone, looking around the precinct, trying to act natural, until the elevator returned empty.

"The skin underneath Travis' fingernails doesn't match his siblings," Lanie explained as Tony walked through the door, suddenly all eyes on him.

"You're late, DiNozzo."

He quickly glanced at Castle and then back at his boss. "Sorry, boss, I took a wrong turn and lost the group. Won't happen again."

"But we're running the skin against the unidentified prints," Abby continued.

Gibbs turned to Ducky. "Duck, why don't you and Jimmy get started? And call me if you find anything."

"You'll know as soon as we know, Jethro," Ducky said as he and Palmer followed Lanie to where the third body was.

"Detective Beckett," Gibbs began. "Can I get my team into the apartment?"

Kate nodded. "Ryan, Esposito, take Agents David and DiNozzo to the crime scene, please?"

The four of them left and Gibbs turned to McGee. "Was there a computer found?"

"I'm running test on it now," McGee answered. "But it's going to take a while. Corporal Moore did not know the meaning of organization."

"Keep an eye on it and keep my updated," Gibbs said.

McGee nodded at him. "On it, Boss." And then he disappeared to observe the tests. Then, Kate headed for the elevator, followed closely by Rick and Gibbs.

"So the siblings all shared this apartment?" Ziva asked as she took pictures around the crime scene.

Esposito nodded. "Three bedrooms. Can't imagine it's cheap."

"Nothing in New York is," Tony replied. "Especially housing."

Ziva slowly observed the entire living room, noticing family portraits, pictures of children, teenagers and adults, all in front of the same small diner. "Do we have any information about the diner in these pictures?"

Ryan shook his head as he pulled the frames from the wall. "We just thought it was a family thing."

"We can take them back to the precinct," Tony said. "Abby and McGee can run the pictures and hopefully get us an address. Whoever owns the diner might be able to give us more information."

"We have to be missing something," Ziva said as she spun slowly in circles, looking for nothing in particular. "Nothing was broken. There's no blood trail. Where was the 4th victim shot in order to not leave a trail?"

Tony continued. "There was barely a struggle. It's almost as if they knew their killer."

"So why would they let him or her shoot? Why didn't one of them stop the killer?" Ziva questioned.

"Maybe there wasn't enough time," Tony answered. "Maybe the shots came one right after another. Two, two, two. No breaks, no time to think."

"You two sound like Castle and Beckett," Esposito said and Tony and Ziva glanced at him.

Ryan smiled. "You guys even glare like they do."

Tony smiled now. "Speaking of them, are they a couple? Because they give off the couple vibe."

"You mean like you and Ziva?" Ryan questioned.

Suddenly, Tony's smile faded. "Have we found any bullet holes yet?"

Both men shook their heads. "There's nothing. It's like you said, something's missing."

"Well, then let's try to find out what it is," Ziva said as she grabbed the camera and headed for the door, the three men following her.
