The luminous point gradually increased, and now I am surprised to see the black surface of the stone door. The luminous point turned out to be a round handle on it. She looked like some kind of crystal in a metal frame. Glare from him fell on the dark surface of the door, but what was on it was visible badly. I ran my fingers through the drawing - the heart missed the blow, followed by the second, I even stopped breathing - felt for my head - a three-headed snake was carved on the stone surface.
