Případ dvou sester

Mr. Laffler is strange. Everyone in the office he runs knows that. The clerk, Costain also knows this, so he is very surprised when his otherwise impersonal boss does something as human as inviting Costain to dinner. But not at home. At home, he says, he does not accept guests. He leads him to an inconspicuous, secluded restaurant U Sbirra, where a very closed company of strange people meet.
