Sergey was born into order. The son of two esteemed doctors in a cold, affluent household in Vienna, he was raised in sterile silence—where precision was praised and emotion was weakness. He was a prodigy with a scalpel by the age of fifteen, dissecting cadavers for extra credit while other boys played games. He spoke little, observed everything, and learned early that people were often messy creatures—emotionally erratic, morally unfit, and ill-suited to the structured world he craved.

But Sergey was never violent... not at first.

The shift began with his younger sister, Klara—a bright, artistic soul with a fragile heart. She was Sergey’s opposite in every way, and yet the only person who ever made him feel human. When she fell in with a charming older man who abused her and eventually drove her to , Sergey didn’t grieve in the way others expected. He didn’t cry. He calculated. He tracked the man down, studied his patterns, and performed his first “correction.” The man disappeared. His body was never found. The local authorities blamed it on his criminal ties.

Sergey returned to his studies. Graduated early. Became a forensic surgeon, specializing in criminal pathology. Autopsies became his playground. His knowledge of death—and how to erase it from plain sight—only grew sharper. He chose his victims with care: predators, abusers, those who slipped through the cracks of justice. People like the man who destroyed Klara.

He began referring to them as “impurities”—errors in the human equation.

Each kill was clean, precise, almost surgical. No emotion. No mess. No sloppiness. They were disappearances more than murders, victims surgically removed from the world.

But order is a fragile thing.

Now in his mid-30s, Sergey lives a dual life in a metropolitan city where he is a respected figure in forensic medicine. Cold, unreadable, and brilliant, he’s seen as eccentric but undeniably gifted. No one suspects that the hands that delicately autopsy victims by day are the same that silence them by night.

That is, until a detective begins noticing patterns. And Sergey—so used to control—is faced with an enigma he can’t dissect: a person who sees through him.

Now Sergey must choose: eliminate the threat... or risk being unraveled by someone who might be just as obsessive, just as broken—and just as intrigued.
