In the courtyard of a crumbling tenement house the guests sit in a sawn-open Trabant and in a bathtub lined with cushions, the DJ is warming up in the dance hall, and the bar has just tapped a fresh barrel. Vazul, the owner, had announced that he would sell the house to an investor at the end of the summer – not everybody was happy about that. Shortly before midnight the clatter of the table football on the gallery stopped, and Vazul was found lying beside the table. Everyone who was in the pub gives a short statement – find out who was alone with him.","rules":{"standard":["Every row and every column holds exactly one person.
