Čtyři měsíce sdílelo devět lidí chatrče, hučení generátoru a vytí huskyů a nejnovější ledové jádro právě ukázalo něco, co jednu kariéru založí a druhou zničí. Vigdis, vedoucí stanice, chtěla výsledky vyslat domů rádiem, jakmile se vrátí slunce. Už se k tomu nedostala: našli ji v laboratoři, vedle ledového vrtáku. Zvenčí nemohl přijít nikdo – každý podává výpověď, zjisti, kdo byl s ní sám.","rules":{"standard":["V každém <b>řádku</b> a každém <b>sloupci</b> je přesně <b>jeden člověk</b>.
