It could be a detective. In a mystery story, a detective might be following a suspect secretly, so the footsteps behind could be his.
Maybe it's a lost soul. In a supernatural story, a lost soul that is wandering and somehow latches onto the main character could be making those footsteps. They might be trying to get the character's attention or lead them somewhere. For instance, in some tales of the afterlife, a spirit who has unfinished business might follow a living person by making those footsteps until the person figures out what the spirit wants.
It could be a curious child. In a story set in a small town or a big house, a curious child might be following someone out of pure interest. They might not have any bad intentions but just be intrigued by what the other person is doing. So the footsteps behind could belong to this innocent yet inquisitive child.
It could be a vengeful spirit. Maybe someone who had a bad experience during Christmas in the past and now haunts the place, leaving those footsteps as a sign of their presence.
It could symbolize mystery. Maybe there is someone or something following in the story that is not yet revealed, adding an element of suspense.
I don't know as I haven't read the book. But it could have a detective as a main character if it's a mystery novel related to the footsteps in the dark.
The 'Footsteps in the Dark' novel could potentially revolve around a character who is being haunted or followed by these footsteps in the dark. It might be a thriller where the main character has to figure out who or what is making those footsteps before something bad happens to them. Maybe it's set in an old, spooky place like an abandoned mansion or a dark forest.
I heard a footsteps scary story from my grandfather. He was in an abandoned building once. He heard footsteps that seemed to be coming from the basement. He was curious and went to check. As he got closer to the basement stairs, the footsteps grew more intense. He then saw a shadowy figure at the bottom of the stairs. He quickly ran out of the building, and he said he never went back there again.
Well, in many scary stories, footsteps can mean different things. Sometimes they represent the lingering presence of someone who's passed away. For example, in a haunted house story, you might hear the soft footsteps of a former resident who met a tragic end. It creates an atmosphere of unease and mystery, as the characters (and the readers) don't know who or what is making those sounds. And it builds up the tension, making us anticipate something bad is about to happen.
Traveling the Wuxia World was a follow-up to The Phantom Shadow.
Perhaps it's the subversion of expectations. Christmas is a time for family, presents, and good cheer. But this story turns that on its head. The horror elements disrupt the normal Christmas narrative. It makes the reader or viewer feel uneasy as it challenges the positive and warm feelings we usually have during this holiday season.
It could be Naruto's son, if we're thinking in the context of Naruto having a family in the future. He might want to be as great a ninja as his dad and follow in his footsteps.
Footsteps create tension by making the reader wonder who or what is approaching. The mystery builds suspense.
