Russian Literature Bleg

You weren’t expecting that, were you?

So there’s a short story from the Soviet era, late Stalin I think or shortly thereafter, about a group of friends and acquaintences with a number of lingering personal and sexual conflicts and jealousies. An official announcement is made by the government that for one day, Soviet citizens will be allowed to murder one person without any legal reprocussions. The story revolves around the ways in which this group of people prepare, offensively and defensively, for that day.

If anyone has a clue about the author or title of it, I’d be immensely grateful.
