Od czterech miesięcy dziewięć osób dzieliło baraki, buczenie generatora i wycie husky, a najnowszy rdzeń lodowy właśnie pokazał coś, co jednej karierze da początek, a drugą zrujnuje. Vigdis, kierowniczka stacji, chciała przesłać wyniki radiem do domu, gdy tylko wróci słońce. Nigdy tego nie zrobiła: znaleziono ją w laboratorium, obok wiertnicy lodowej. Z zewnątrz nikt nie mógł przyjść – każdy składa wypowiedź, ustal, kto był z nią sam na sam.","rules":{"standard":["W każdym <b>wierszu</b> i każdej <b>kolumnie</b> jest dokładnie <b>jedna osoba</b>.
