White

White, a cool, calm, experienced investigator, is working on a case that has been plaguing the entire department for almost two years. Frequent, almost daily, murders remain unsolved, with no traces or leads, and the killer is clever and precise. He calculates every step, knows when to stop, and what to do with the victim.

The killer is a freshly recruited investigator. He has a higher education, three years of experience, and a background check. He manages to juggle work and murder, and never forgets his alibi or his own life. His murders are works of art, creations that cannot help but generate passion and admiration. Fine workmanship, with millimeter precision. A true psychopath.

White sits in his office, lazily looking through papers, comparing reports and involuntarily glances at the board where for a year now there has been hanging one piece of evidence, the only one, on this killer, who was nicknamed "the ripper".
