You've Been Assassinated.

Hayden had always done one job and one job only. He never worked at a fast food restaurant like a normal teenager, no not even close. Since the day Hayden turned 18, he had been an assassin. He was hired for big bucks, and he never failed to execute the target, that is, until one day. Hayden had been called in by a man named Fredrick to assassinate a land owner, an easy job for a professional such as himself. But this job proved to be harder than the rest. It seemed that their were many people out to get Hayden, and they were hot on his tail. They had figured out his killing patterns and everything. Will Hayden be able to execute the target and receive his payment, or will he himself become the real target?
