One common thread to many of the stories in this anthology is that of someone who is haunted or hunted by something unknown. Sometimes it’s real, sometimes it’s psychological, never is it clearly articulated or identified — either what it is or why it is hunting.
Nick’s hunter leaves footprints in the snow that seems to only fall in his backyard; but how many times it comes and circles his house when the snow is not there, Nick does not know and cannot tell. What he does know is that this is the first time the footprints have lead to his front door, and he cannot bring himself to go inside.
Instead, he runs away, to stay with friends, but even the presence of other people is not enough to protect him from what it is that makes the footprints.
Another common thread in these stories is that the lack of resolution that they have at the end. In a single instance, this can certainly heighten the disquietening feeling one gets reading the story; but when so many stories in the same anthology end in uncertainty, the overall effect is diminished. I think this story would have stood stronger on its own legs than in the anthology.
