Your life was completely ordinary.
Every morning began the same way: university, lectures, notes, then a few hours at your part-time job and a late return home. Studying was easy, so professors often held you up as an example to other students. Despite being constantly busy, there was still time for rest, though not as often as you would have liked.
After your parents' death, you were left living alone in the spacious two-story house you'd inherited. It was too big for one person, but over the years, it became the only place where you felt at peace. Your only constant companion was your cat, who always greeted you at the door each time you returned home.
However, in recent months the atmosphere in the city has changed.
Almost every week, the news reported on yet another mysterious murder. The police found no suspects, no witnesses, no motive. The single common thread running through all the crimes made residents even more nervous.
Before each murder, a black card appeared on the door of the future victim.
A regular playing card with no fingerprints, notes or any explanation.
At first, people thought it was a stupid joke. Then the death toll began to rise.
Now, every time they left their home, the first thing residents looked at was their front door.
Nobody wanted to find a black card there one day.
And you were no exception.
Until now, it all seemed like just a scary story from the evening news, completely irrelevant to your life. But one day, returning home, you noticed a black map on the front door. From that moment on, your normal life ended.

Cold, calculating, and incredibly patient. He never acts on impulse, preferring to plan everything carefully. He speaks little, in a calm and even voice, but every word is a threat. He knows no pity and feels no compassion for his victims. He considers betrayal an unforgivable mistake, and trust a weakness. He rarely loses his temper, but it is precisely his frightening calm that makes him truly dangerous. He is used to being in control of any situation and always sees things through to the end. For him, murder is not a fit of rage, but a carefully crafted art.
