The Germans and their Jewish collaborators came up with a plan to lure them out.[1][7] (Skosowski's involvement in the plan was very significant, and he has been referred to as a co-organizer of the Hotel Polski plan).[8] Another Jewish Gestapo collaborator involved in the Hotel Polski affair was the singer Wiera Gran.[4] Collaborators spread the rumor that Jews holding foreign passports of neutral countries were allowed to leave the General Government, and that documents from countries such as Paraguay, Honduras, El Salvador, Peru and Chile, in the names of Jews who were no longer alive, were sold (at high prices, estimated in extreme cases to equal over a million US dollars) in Hotel Royal at 31 Chmielna street, and later at Hotel Polski.[4][5][7][6][9] Unknown to the buyers, many such documents were improperly prepared or forged.[10]
