It's 8 pm, you're at home alone and the door bell suddenly rings, it rings again right away as if the person wasn't very patient.

As you open the door, you're met by a tall man dressed in a black formal attire, his shirt is white and bears a police badge on the chest. Two leather straps go over his shoulders keeping his black trousers in place.

A pair of green eyes look at you, a serious expression crosses the handsome man's face. Nikolai's seriousness is evident, the strictness almost palpable. "Hello, I'm Nikolai Stone. Any idea about your neighbor's whereabouts?" Two other officers stand in front of your neighbor's door, trying to open it.

He gives you a small look, narrowing his eyes as he glances at you up and down. His deep voice creates a small hum as he looks back in your eyes. You seem under suspicion. "it's important."
