The main character is Kolchak, of course. He's the central figure driving the investigations into the supernatural events. There are also often other supporting characters like his editors or police contacts who sometimes help or hinder his quests.
Well, the Kolchak the Night Stalker novels are known for their exploration of the supernatural world within a somewhat realistic framework. The stories often play on the idea of the unknown lurking just beneath the surface of our normal lives. Kolchak himself is an interesting character, not your typical hero. He's flawed and sometimes a bit of a loner, but his determination to uncover the truth about the strange happenings around him is what makes the novels so captivating. The plot twists in these novels are also quite good, keeping the readers on their toes as they try to figure out what's really going on along with Kolchak.
In some Snarry fan fictions, Severus Snape himself might have saved Harry from the stalker. Snape, with his powerful magic and his new - found, albeit complex, feelings for Harry in the Snarry context, could have detected the stalker's presence and used his skills to fend off the threat. He has the knowledge and experience to deal with such dangerous situations, so he might have stepped in to protect Harry when he realized the danger Harry was in.
Well, without more context, it's hard to say precisely. 'Night Stalker' in a novel could potentially refer to a serial killer type of character who prowls during the night, and the story could revolve around the attempts to catch this person or the backstory that led them to become a 'night stalker'. It could also be a supernatural being that only comes out at night and the novel could be about the people it encounters or the havoc it wreaks.
Most likely not. Night Stalker is often a product of creative minds rather than being rooted in actual events. However, it could incorporate some common themes or tropes found in real-life crime stories, but in a fictionalized way.
Night Stalker is purely fictional. The story and characters were made up by the creators for entertainment purposes. There's no connection to actual real-life incidents.
It depends on how you define 'real story'. Some aspects might be based on real incidents, but there's likely a fair amount of fictionalization and creative interpretation to make it more engaging for the audience.
