Blue Wings

A strange story happened at a mine. One day, the chief accountant, Semyon Petrovich Krinichkin, returned from town with a purchase he didn’t want to show anyone. But he still dropped the package, and everyone found out that he had several meters of blue fabric…

Why did he, the accountant, need it? The whole settlement tried to figure that out. Everyone wanted to know what he did at night when strange sounds came from his house.
