The Floater

Chapter 1

Marcus Blake moved his head to the music on his phone as the elevator rose. With a ding the doors opened and he walked onto the floor. He removed the headphones as he entered the bullpen to a heated discussion.

"Mcgoo tell the woman the year was 1915." Tony said

"I know for a fact that the year Oreo was created in 1912." Ziva said crossing her arms and leaning back in her chair.

"I'm staying out of this." Mcgee said crouched at his computer.

After a few more minutes of arguing Tony turned away and looked at the man standing in front of them. He was slim with black short hair and well-kept beard, wearing a light gray sweater, with gray pants and shoes. His eyes were a deep green and he wore a green messenger bag.

"Who are you?" Tony asked

Marcus reached into his bag and pulled out a paper and handed it to Tony.

"I'm Marcus Blake and I was told to give this to a Leroy Gibbs." The man said with a smile.

The three agents looked over the paper and each nodded.

"Well he left a few minutes ago. He should be back soon." Ziva said

Marcus nodded then his eyes drifted to the big screen.

"Well, well what do we have here?" He asked

The three agents turned to each other, until McGee stood up.

"We have a Petty Officer found dead well on Liberty."

Marcus let out a small chuckle, "I must needed break for our men and woman on the seven sea's. What happened?"

Tony took over, "It looks like a mugging gone wrong."

Marcus grunted, "Can I see the case file?"

Again the three agents looked at each other and shrugged.

Quickly flipping through the file Marcus handed it back.

"You say he was single yet there is the faintest tan line on his right hand. If the stories I heard about your Dr. Mallard are true he would have found this anyway, but anything that gives you guys a head start works right." Marcus said with another smile.

Mcgee and Ziva looked at each other and headed back towards there stations, while Tony squinted at the picture trying to find the clue. Only to fall to a Gibbs head slap a moment later.

"Dinozzo do you need glasses?" Gibbs asked

"No boss"

"Then get back to work."

With a quick "Yes boss" Tony returned to his desk.

Gibbs stopped in front of Marcus raising an eyebrow.

"Marcus Blake sir, I was told to report to you." The young man said holding out his hand.

Ignoring the hand Gibbs took the piece of paper and looked it over. As he finished his gaze moved up to Vance who was staring back at him. Gibbs pushed the paper back in his hands and headed towards Vance's office.

"Which floor is the Forensics lab on?" Marcus asked

The question caused the rest of Team Gibbs eyes to widen.

"Really Leon you want to give her another "assistant". The first one framed Dinozzo, and tried to kill her. The second one was the guy who committed the crime, not to mention she punched him the face. That is proof that she works best alone." Gibbs tried to persuade.

"It is only for a day Gibbs, besides the guy will be a floater. He'll head to areas that need him. Besides he is more than qualified." Vance said throwing Gibbs a file.

Gibbs looked threw it and began to read sections, "Name Marcus Edward Blake 27, Masters in Criminal Justice, and Forensics Science, PhD in Forensic Psychology. That is great but what is the kid doing here Leon. His FLETC scores seem advantage, and he passed the polygraph. But with his smarts couldn't he be making millions at a .com or something ? Also why assign a Probie agent to my team?"

With a slight smirk Vance threw Gibbs another file.

Gibbs eyes widened as he read it, "Are you sure about this kid Leon?"
"Right now 50/50 but that is why I have him assigned to your team Gibbs, if he is up to no good, then I trust your team to take care of it."

With a simple nod Gibbs left the office.

The roar of music found Marcus as he entered Abbie's lab.

"Hello." He said. There was no response. "HELLO!" He shouted.

Abby jumped and turned around. "Geez you could scare a person to death. Who are you?"

"Marcus Blake and I've been told to work with you today." He said with a smile

Abby frowned, "I work better alone"

Marcus chuckled, "I know from what I heard your 0-2 for others in the lab, but it is only for a day. I only need to finalize a few case records, and I don't need much space. Plus-"He pulled out a Café-POW. "I was told this would help us get off on the right foot. "

Abby stared at the young man and back at the Café-POW before sighing in defeat.

"You can use the spare desk over there." She pointed and grabbed the drink.

With a small smile Marcus headed toward the desk and placed his bag down and pulled out a pile of case files, and a note pad. He plugged in his head phones and let the music take him away.

It seemed like a moment later that Abby was poking him on the shoulder; quickly he took out his head phones.

"It's time for lunch." Abby said

"Thanks but I have a lunch from home." Marcus said

But the young man turned to Abby who was tapping her foot.

"Oh you don't trust me alone in the lab. Got tach." He gathered up his stuff and left the lab.

A few minutes later Marcus found himself sitting across from Abbie's lab eating a sandwich and looking over another file, when Mcgee and Tony walked by.

"I told you Mcgeek it was 1912."
"No Tony you said 1915." Mcgee said

"Who cares anyway?" Tony said

Both men walked into the closed door.

"Ow" Both said as they turned around to see Marcus.

"Where is Abby?" Mcgee asked

"At lunch."

"And you are out here because?" Tony asked

"She doesn't trust me in the lab alone."

"Okay by why are you here and not in the cafeteria?" Mcgee asked

"Too much noise. I work better in quiet places." Marcus said as he got up. "Which way is it to autopsy?"

The two agents pointed the way. Well Marcus gave a nod.

"Well it seems that you met a grizzly end my friend for mere pocket change as well. What a shame." Ducky said

"The instruments are ready Doctor." Palmer said

Both turned when there was a knock at the door as with a wave Marcus walked in.

"Hello I'm Marcus Blake and I'm helping finish some case files. I was wondering if I could look at your notes from the Bleacher case. I want to make sure that my numbers are right." The young man.

"Of course Mr. Palmer get this young man the file." Ducky asked

With a nod Palmer walked away to get the file while Marcus walked over to the corpse with Ducky.

"This is the victim for Team Gibbs?" He asked

"Yes it is."

"Upstairs I noticed a tan line on the ringer finger on the right hand. It seemed very faded. Of course I could be wrong, if you could confirm it Doctor."

Quickly Ducky looked over the victims hands and found the tan line.

"Good that means hopefully I didn't waste those agents time following a false lead." His eyes then moved to the stab wounds. "There is something strange with these. On first glance one would think that the knife has teeth, but looking closer it seems like the killer twisted the blade. That means either the knife was stuck, or they wanted the cause the victim more pain. I am sure that you out which Doctor." Marcus said with a smile

Ducky simply stared at Marcus for a moment, when Palmer arrived and handed Marcus the file. After a few seconds he wrote something down and handed the file back to Palmer.

"Have a good day gentlemen." Marcus said leaving

"What a peculiar young man." Ducky said

The rest of the day went by in a quick blur as once he was finally finished Marcus gave a big yawn.

"Well I'm done for the night. How did I do today?"

Abby looked at him, "You weren't terrible to work with."

Marcus grinned, "I'll take that as a win." As he was leaving he placed another Caw-POW on her desk. "Have a good evening Abby."

"You too Marc" The Forensics specialist said with a small smile.

Marcus simply stopped at the entrance and shook his with a small grin.

He entered the bullpen after dropping off his files to see three tried but happy agents.

"So how were your day guys?" He asked

"We solved the case." Ziva said

"Yeah and thanks for the tip about the tan line. With that that McHack was able to find out that the Petty Officer was previously married, but ended it a year before he entered the navy. It seems the ex was waiting until he returned home to take revenge." Tony said

"No thanks needed; I am sure anyone could have found it, Goodnight agents." He said

A chorus of Good Nights followed him as he entered the elevator. A moment before it closed Gibbs stepped in. The elevator went down a few floors until Gibbs turned it off.

"Kid why are you here?"

Marcus sighed, "I guess it was a little too much to ask for at least one day when no one knew. I guess you know that money isn't a problem. Look Gibbs with my smarts, landing a job almost any job wouldn't be a problem. But the people could be. Like it or not your team is impressive almost legendary, and they seem like my kind of people."

Gibbs stared at Marcus for a few moments before he turned the elevator back on. As the door opened Marcus reached into his bag.

"I'm not a craftsman but I figure a man like you can always use another hammer." He said taking out a hammer and handing to Gibbs as he left the elevator. "See you tomorrow." Marcus said.

As the door closed Gibbs smirked it was a nice hammer.
