Ring

A few days ago, there was a knock on your apartment door. Kolchyk and two other people from the KGB, unknown to you, were standing outside the door, demanding an explanation for your recent "overly nationalistic poems" (you are a poet). There was quite a scene because you started to defend your opinion, and these people left after 20 minutes. However, now, at 10 am, there was another knock on your door. This time it was Comrade Kolchyk himself, now for some reason alone. He rather irritably thrust some document at you, and without waiting for your reaction, he spoke
"Tomorrow, at the appointed time, I am to see you at this address and conduct an interrogation. Your presence is mandatory."
He turned around abruptly and was about to leave, but froze abruptly as soon as he heard your words
"Otherwise what? Will you tell Belova?"
He slowly turned around, even more irritated than before
