Welcome to my NCIS/ Alex Rider crossover! This is a story idea I've been thinking about for days now and I thought it was a good time to begin. Hope you love it! Anyway, here are two things you need to know:

1. This is shortly after Alex Rider's adventure in Ark Angel. It seems fitting since Jack is already staying in Washington D.C.

2. This is randomly in between seasons 6-9 in the NCIS timeline.

I do not own Alex Rider or NCIS. Although, I have met Anthony Horowitz and I'll just say that he is one of my fav authors.

Chapter One: In the Beginning…

A small stone bounced noiselessly across the street and into a gutter; something that could only happen if a car or bike knocked it out of the way or if someone had kicked it. Indeed, the latter had happened. Alex Rider was walking down that very street, minding his own business. It had been two weeks since his ordeal with the ruthless Nikolai Drevin, two weeks since landing in the South Pacific Ocean near Australia after destroying Ark Angel and exactly one week since moving in with Jack and her parents in Washington D.C.

It had been decided, after being dragged aboard the USS Kitty Hawk that he would stay on an SAS military base. But Alex, determined to be reunited with Jack, insisted that he be sent to America. The journey took two days, by plane, and the whole time, Alex couldn't help but wonder what would happen if Ark Angel had made it's catastrophic crash on the Pentagon. Millions would have been killed, that was for sure. But what about him? MI6 only wanted him for missions but where would he live once they didn't need him? After the near 48 hours of contemplation, Alex decided it would be best to shove those thoughts from his mind.

At last, here he was, on the way back to the house. He had told Jack that he would be at the house by 6:00 and his watch told him he was running out of time. Maneuvering around dozens of people, Alex suddenly missed the semi-quiet streets of Chelsea; Washington was so busy. Around the time when his watch said 5: 45, Alex heard a gunshot from across the street. He ducked instinctively, but regained his posture after realizing that it wasn't aimed at him. Instead, he turned to face the building where the noise had come from, just in time to see a stream of people running from a building with a great dusty sign overhead: Romano's Bar.

Without thinking, Alex sprinted across the street, ignoring the blaring car horns, and faced the bar. He dove into the rush of people, them being unaware that a child was heading in the opposite direction. He soon found himself in a bar room littered with tables and glasses. The room had a strong smell, making Alex wrinkle his nose in disgust. He was about to leave when he heard voices coming from a back room. Angry voices.

Careful not to make any noise, he tiptoed to the door, thankful that it was ajar. Looking in, he found two men; one was holding a pistol in his right hand and holding the second man against the wall with his left. Alex noticed that the man against the wall was looking pale, blood was dripping from a wound in his foot. The man holding the gun suddenly spoke.

"Now," his voice was raspy, as if he had a sore throat and was out of breath, "I really didn't want to do this, Leon. I'm your mate, y'know. But Caspian wanted the goods you stole last week."

"I don't give a damn what Caspian wanted. I quit, remember?" the man called Leon said.

"You should know better than anyone that you can't just quit. You're a dead man, Peters." Another shot was heard and plaster rained down on the both of them.

Alex stuck his head in a bit further until he could see Leon. The other man had his back to him but Alex saw that the man had a tattoo of a star on his neck. This could be useful later. Leon suddenly reached for the gun.

"Be reasona-."

Another shot made Alex cringe and close his eyes. When he opened his eyes again, Leon was lying on the ground, his hands frozen at his throat. The other man was gone.

"Oh my god."

Alex spun around to find a tall, policeman staring at him. No, not him, the body behind him. Alex cursed himself quietly. A man was dead and he, Alex Rider, was caught at the crime scene. The policeman glanced at Alex then walked past him. He knelt beside the dead man and felt his neck. "Ugghhhh…" he groaned as he withdrew his hand, which was now crimson. Then he noticed something glimmer on his neck. At first he thought it was the bullet but then he saw it was a rectangle. A dog tag.

"Army," he said to himself, "Or Navy…" he turned to see Alex. "You need to stay here."

"I need to be home by 6:00." Alex said simply.

"Do you have a phone? A number we can contact?"

"Here." Alex produced a small white cell phone and sat down at a nearby table. He already knew what the officer would tell Jack.

"Okay, what have we got here?"

Jethro Gibbs' watch said 6:45. The entire NCIS crew minus Abby Sciuto and Ducky Mallard was crowding around the body of Leon Peters. He was still in the position he was in at his time of death.

"Tag says 'Leon Jacob Peters.'" Timothy McGee said, taking pictures of the corpse with Tony. "Notice the bloody ring on his finger? He's married."

"No duh, McGenius." Tony mumbled.

"He's covered in bits of plaster." Ex-Mossad, Ziva David, pointed out. She looked up. "There's a bullet lodged in the ceiling, yet it's not the one that shot him."

"Found it!" Tony dropped his camera and reached for his latex gloves, having spotted a glint of red and silver beside the body. He held it up to the light.

"Stop staring at your reflection and get it over here, Tony." Gibbs said. Then, he pointed at Leon's body. "Get this to autopsy, we need to know what happened."

"I know what happened."

The entire crew spun around to see a young boy with blonde hair sitting at a nearby table. He seemed completely at ease watching them, a bottle of water in his hand. He seemed ordinary enough: plain jeans and a red tee shirt.

"Who're you?" Gibbs asked.

"Alex Rider, sir." Alex said, putting down the bottle and standing up. "I had to stay here as a witness."

"A witness?" Ziva asked, curious.

"Yeah, I…saw what happened."

There was a split second when Gibbs looked back at his team. Then, he made up his mind.

"We're all going back to HQ. DiNozzo, the kid goes with you and McGee. Let's move!"

Alex took a deep breath and followed the team out.

"Hey kid, you're with us."

Alex turned and followed the two men standing in front of a black Honda and slid into the back seat. They drove off.

"So, kid-." Tony began.

"Alex."

"Alex, sorry. You sound British."

"I am. I'm from Chelsea."

"What're you doing here? Holiday?"

Alex hesitated. He didn't know how much he was allowed to reveal. "I'm…here…visiting my grandparents." Well, Jack's parents might as well be.

"Ah," Tony said. "The old Gramps and Grams."

"Ignore Tony," the other man said turning around. "He's younger than you."

"Shut up, McGoo."

"Are you two good friends?" Alex thought. They sure reminded him of himself and Tom. Just older.

"Professionally speaking." Tony said, pulling up in front of NCIS headquarters.

How was that? PLEASE review.
