It was just a regular day at the police station for me, Noah. As a senior officer, I was accustomed to dealing with various cases and criminals. However, I had no idea that the upcoming case would leave me both baffled and horrified.

It all began when Commissioner James summoned me to his office. He briefed me about a series of murders that had occurred in our city. Five victims - Anna, Mary, Helen, Eva, and Irene, had been brutally murdered in different locations. The only commonality among them was their connection to the police force. Anna was the wife of a police officer, Mary worked as a nurse at the hospital where the commissioner's wife was being treated, Helen's father was a retired police officer, Eva was a press reporter, and Irene was the daughter of one of our colleagues.

The killer had managed to evade capture for months and was now being referred to as 'The Oliver'. He was a psychopath who enjoyed playing mind games with his victims. What made him even more dangerous was the fact that he was well-known among the people, yet no one suspected him.
