Not having access to 'The Lookout Man' by Nicolas Bentley means I can only speculate. The lookout man is the obvious main character. There might be a mentor - like figure who trained him for his lookout duties. Or there could be a villain - like character who tries to disrupt whatever the lookout man is protecting. There may also be family or friends of the lookout man that play a role in the story, even if they are not directly involved in his lookout activities.
Since I don't know the story, it's hard to determine the main characters precisely. The lookout man is likely a key character. There could be other supporting characters such as fellow workers if he's part of a team, or local people in the area where he is on lookout. Maybe there's a character who causes trouble or a person who needs his protection.
I'm sorry, I haven't actually read this story. But generally, in a story, the main plot could involve the lookout man's experiences, perhaps his duties, the challenges he faces while on lookout, and how he interacts with other characters in the story.
I haven't read this story in detail. But generally, it might be about a lookout man. Maybe he has some special tasks or experiences that the author wants to convey.
Perhaps the story is about the lookout man's struggle with boredom during long hours of looking out. He might have to find ways to keep himself awake and focused. Another plotline could be that he has a past that haunts him while he is on duty, and it affects his performance as a lookout.
Since I don't know the exact 'the lookout man story', it's hard to say. But surely the lookout man himself is a main character. There might also be people he reports to, like a captain if it's a ship - related story.
The main characters are Bentley and Penelope, of course. But in addition, there could be a mentor - like figure who is involved in their lives. This person might unknowingly fuel their jealousy. For example, if the mentor gives more attention to one of them in a particular skill or activity. There could also be a family member of either Bentley or Penelope who notices the jealousy and tries to give advice. And then there could be a group of friends who are caught in the middle of Bentley and Penelope's jealousy feud, not really knowing which side to take.
It seems that Maci and Bentley are the main characters. Maci, as the teen mom, is at the heart of the story. Bentley, his role is not entirely clear without more details, but he is an important part of the 'bentley and maci teen mom story'. He could be Maci's son, which would mean he is a major factor in her life as a teen mom, influencing her decisions, growth, and the overall narrative of her experience.
Occasionally, there are characters who seem a bit of an outcast in society. These are the ones who are more likely to stumble upon the strange happenings in his fictional worlds. They might be the loner at work or the person who doesn't quite fit into the social norms of their community.
There's not much information given just from the title, but he could be an ordinary person with an extraordinary past. Maybe he was a local hero who left under mysterious circumstances, and now his return is stirring up all kinds of emotions and expectations in the community.
Without more information, it's hard to say who Caroline and Nicolas are exactly. They could be ordinary people with an interesting story, or they could be characters in a fictional narrative.
