The town's detective branch are known for their speed and intelligence. In many cases, the detectives were able to solve mysteries in only a few hours. The reason why the detectives are so intelligent is due to the mayor of the town, who is very selective on who he allows to be hired into the police force. All employees are required to have went through college and obtained a relevant degree. They must study under only the most famous and difficult schools. Only then may they qualify for the police force. But there was one case in 2016 that the town will never forget. In 2016, a small town experienced a string of murders. The police force wasn't prepared for what they were about to get into. Rarely did the police force have to tackle a murder case, but detectives in town had yet to investigate a serial murder. Even though the detectives were incredibly skilled, this specific case was impossible.The evidence was all over the place and the motive was unclear. The head of the detective branch decided to do something against the mayors wishes. The boss, commonly nicknamed as the "mysterious detective", went on to enroll a year 2 college student who had no experience in the field. Amy was her name. She had came from a successful family and because of her parents' generosity and funding Amy was able to pursue her dream as a matchmaker soon after high school, running her own business in a shiny, huge building. The detective must've seen something in Amy, and, to everyone's surprise, the mayor permitted the mysterious detective to allow Amy to work in the police force.
