Z- Zero or ZedTony was sitting in his office at stark industries. He inherited the company four years ago when he turned 21. He was only 20 when his parents died. He didn't do much but he did have an office and had some say in how the company was run. The secretary came into his office while he was daydreaming and interrupted it.
"Mr Stark?" The secretary asked
"Yes" tony said.
"I've got a package for you" She replied
"From who?" He asked
"It doesn't say" She replied
"Really?" He asked.
"Yes sir." She replied
She handed him the package and she walked out of his office for him to look at it.
It contained a Walkman. And some papers. He decided to listen.
"Anthony Edward Stark. You must be wondering who mysteriously sent you this package. Well let me introduce myself. I am (letter) this is the name I go by and that name you will hear it whenever I am in contact with you. You will refer to me as "(letter)". I am a detective and also an assassin but in this case I will be a detective. I am one of the best. I have been given this case by a certain someone in a high position. I will give them the name of Al. Al is concerned that the weapons manufactured by your company are being used by terrorists. I will look into this and you will help me out by providing the names of your clients and the organizations that buy your products. My messenger who goes by the name of Walker will confront you and you will do as he says. Don't give me trouble Mr. Stark and follow my orders. It is a pleasure to be working on this case with you." You said
"What the hell?" Tony said to himself.
He looked up the letter of your name and found out that you are a well known detective who has only been around for a year but you have helped so many cases be solved and you've even worked with governments around the world to help solve cases. Nobody knows who you are just that you go by that letter and you only make contact through Walkmans and letters. Also by your messenger Walker.
He looked at the papers you had sent him and they were just instructions on how he will be contacted and how nobody should know about this and he should burn the items that were in the package. It also said that Walker will contact him in two days around 6pm. He did as he was told and awaited for Walker's instructions.
