It was an early morning in New York. An extended case of murders was finally solved ~ surprisingly, by a new rookie detective named David. David was a student from a regular college who was observant; he was a big fan of detective novels, he usually wears “detective cloth” to look professional and is tall for his age.

Nobody in town could solve the mystery of chained murders, he was the only one who hadn’t tried yet. He started with everyone and their relations. He had a friend who was popular but had some bad habits such as smoking, drinking, and partying late at night.

His friend had a connection with all of the victims. He reluctantly pulls his friend into a trap where he reluctantly interrogates him. He says he is not guilty, but many people point toward him. The sheriff that has just replaced the old one agrees as well. David’s friend then pled guilty to all of the cases and planned to have his execution in a month.

A month later, he was scheduled for execution at noon. On the other hand, David happily receives his reward money, trying to forget his friend and the pain. Suddenly his computer got hacked at 11:40 A.M with a message saying that he got the wrong person and talking about “their” plan that killed the people. But it was too late… Or was it…
