Neljän kuukauden ajan yhdeksän ihmistä oli jakanut majat, generaattorin hurinan ja huskyjen ulvonnan, ja uusin jääsydin oli juuri paljastanut jotain, mikä tekisi yhden uran ja tuhoaisi toisen. Vigdis, aseman johtaja, halusi radioida tulokset kotiin heti, kun aurinko palaisi. Niin ei koskaan käynyt: hänet löydettiin laboratoriosta, jääkairan vierestä. Kukaan ei voinut tulla ulkoa – jokainen antaa lausunnon, selvitä, kuka oli yksin hänen kanssaan.","rules":{"standard":["Jokaisella <b>rivillä</b> ja jokaisessa <b>sarakkeessa</b> on täsmälleen <b>yksi henkilö</b>.
