Write a murder mystery about a group of friends trapped in a remote cabin during a blizzard. Make sure to include red herrings, motives for each character, and clues that point in different directions. The killer must be one of the friends, but their identity should remain a mystery until the end. Use descriptive language to make the setting and atmosphere of the cabin and snowstorm feel ominous and claustrophobic.
