Hi! So, my two loves are Sherlock and NCIS, so I decided why not write them together? This is set in about end of season 10 for NCIS, and AU mid-season 4 Sherlock, you don't need to know much about either show (Wikipedia character synopsises will do (; ) enjoy, and pease review if you liked it, hate it, etc etc, thanks (:

"Someone's about to die, Jethro, and you're gonna need my help to find the killer." It was Sherlock, the man Gibbs hadn't heard from in almost a year, the man who had recruited him, the man who trusted him, the man who put him in charge of shutting down of Moriaty's American branch, the man who had told him he was alive, the man who out movied Tony, the man who was in love with his partner.

"No one's going to die, Sherlock, you're being melodramatic again." Gibbs chuckled.

"Someone is Jethro, I swear." He paused, realising what Gibbs had said, "I am not melodramatic, ever, period."

"Then how do you know Sherlock?" Gibbs started to realise this might not just be Sherlock having "fun".

"Damn it Jethro, he's coming to find you, and he doesn't play fair. It won't be one shot you're dead, it will be a game. You will get a call that someone's dead; perhaps just a random Marine or member or the Navy, or perhaps your ex-wife, a colleague, but someone will die and you will be enrolled into it and it will kill you."

"So how do you propose you stop him killing me?"

"Keep everyone you care about near you at all times. I'm catching the next flight with John, Mary and-"

"Mary?"

"John's wife, she's an asset."

"I'm sorry Sherlock, I know how you felt about hi-"

"Don't be." Sherlock paused. "I'm fine Jethro. I want to meet your team in your basement tomorrow 9am your time, keep your team with you at all times, and anyone else you care about."

"Have a nice flight, Sherlock."

"Stay alive, Jethro."

Sherlock hung up.

"Abby?"

"Gibbs?"

"Are you in your lab?"

"Yeah, why?"

"Get to the squad room, ring Ducky and Palmer and get them in the squad room too."

"Okay Gibbs, are you okay?"

"Fine, Abs, be quick."

"Okay."

Gibbs hung up, replacing his phone in it's dock, took his gun out of his desk and holstered it. He stood up from his desk.

"Boss?"

"Mm?"

"Is everything alright?"

"Stay here. Tony you're in charge. Do not let either of them out of your sight, okay?"

"Yes boss."

"Are you okay Gibbs?" Ellie sounded apprehensive.

"Fine. And Tony?"

"Yeah?"

"Ring Ziva, tell her to be on guard and free for video chat 9am tomorrow or time."

"Okay..."

Gibbs walked briskly to the stair and took the stair two at a time, before disappearing into the director's office.

"Is he... okay?"

"I don't know Tim."

"I don't think I've ever heard him say so much..."

"It's normally a sign that something's wrong, the last time he talked like this..."

There was silence.

"The Navy Yard exploded." McGee finished for Tony.

"Yeah..." Tony paused. "That."

"What d'ya think's happened this time?" Ellie asked.

Tony was silent and started to type on his computer.

"Sherlock Holmes." McGee stated.

"I didn't want to say." Tony replied with despair.

"I heard it too." Ellie added.

"'No one's gonna die, Sherlock.'" McGee recalled.

"'Stop him killing me.'" Tony retorted.

"'Have a nice flight.'" Ellie finished.

"He's coming." McGee stated.

"He brings trouble. Ellie, do you know anything about Jim Moriaty?"

"British 'Consulting Criminal', Tony?"

"The one and only." He took two files out of his desk and threw one to McGee and one to Ellie. "This is our file on him, no one outside of myself, Gibbs and Vance has seen this. McGee get to work on tracking activity-"

"Isn't he... dead?" McGee interrupted.

"He was. Google 'did you miss me?'"

"Was?" Ellie questioned, as both her and Tim googled.

"Ah." It was almost in sync.

"Tim, get on it, Ellie," he paused and wrote a username on a piece of paper and chucked it at her, "Sherlock's Skype; work with him to find possible members of the network over here."

Ellie nodded and plugged in her webcam and headphones, and started reading the file; McGee started reading the file.

"No one leave the squad room. I'm going to find Gibbs."

"Okay."

Tony headed up the stairs. Moriaty was back, and Gibbs was in for it. Sherlock interested Moriaty, he was safe, but Gibbs had just helped Sherlock, he hadn't been interesting he'd just been a helper, who helped shut down Moriaty's 2nd most profitable branch of crime: America. People were going to die; Tony just hoped they'd get to Moriaty before he got too close to them.
