he improvised igloo. Other nights, they had taken turns watching to protect them from prowling wolves, but this night no one could long withstand the numbing cold of the blizzard. So he watched and half slept. Now he caught the rising howl of the wind, and now felt its lull as the deer skins sagged. But what was this? Was there a different note, a howl that was not of the wind?
