Agent Phantom

Our story starts at a hotel in New York City. A young teenager runs out of the fancy building clutching to his chest a small black brief case. He hurriedly calls a cab and zooms off. Right behind him hobbles out an old man clutching nothing but a cane. His long beard droops low to his neck. He also calls a cab. Now, you may be wondering what any of this could have to do with anything important, but all is not always as it may appear.
The old man plops down in the cab's uncomfortable seat and orders the driver to follow the cab in front of them. The old man sighs happily, obviously enjoying himself. He places his hand by his neck and yanks hard. His face begins to stretch, then pops off revealing his face to be a clever and convincing mask. The thirteen year old boy's hair is a dark blond. The cab driver glances back.
"Where did the old man go?" he asks curiously.
"What old man?" the boy asks back. "I've been in here the whole time. No old man"
Finally the cab in front of them comes to a stop. The boy's cab stops also. The boy, known only as phantom, jumped out of the car, his eyes searching for the man he had been following. The boy is a secret agent, doing the government's bidding. He specialized in disguises, and was known for being silent whenever he wanted to. No one knew his real name, he had always just gone by Phantom or Agent Phantom because he could seemingly "disappear". He was one, if not THE best agent in the field. He always had a strong sense of justice, and when he started a mission, you could count on him to finish it.
His eyes searched around until he spotted the man he had been following, still clutching the brief case. Phantom had not been told what was in the brief case, just that it was imperative that he got it back. He followed silently behind the man. The man entered a dark warehouse, glancing nervously behind him. Phantom quickly ducked for cover. The man, apparently not noticing the boy went on in.
Pushing a button on his watch, he whispered in, "I'm in position, Agent 1. I'm going' in for him. Get back up ready."
"Roger, Phantom, ready when you are." The boy smiled. This was the fun part! He tip toed in, hand placed cautiously on his gun, ready for anything. He walked in. BAM!! The last thing he saw was a masked man swinging a shovel right at his head. Then everything went dark.
