I'm not sure who the main characters are as I haven't read the novel. Maybe it has a detective as a main character if it's a mystery - type story.
Not having read the 'Heat of the Night' novel, we can only speculate about the main characters. It could have a strong - willed individual as the main character, perhaps someone who is new to a place and gets caught up in the events that occur during the night. There might be a local figure who has a lot of influence and whose actions are central to the story. And then there could be other characters who are connected to these two in different ways, like a witness or a love interest, all of which would contribute to the development of the plot during the heat of the night.
Well, there's also Sam Wood. He is a police officer in the town. At first, he is somewhat influenced by the racial attitudes of the town but as the story progresses, he also has to deal with the changing dynamics brought about by Tibbs' presence and the investigation they are all part of.
I don't know as I haven't read the book, but it could be ordinary people living in the area affected by the big heat, like a local shopkeeper, a young student, or a hard - working laborer.
One important character is Virgil Tibbs. He brings a different perspective to the town as a black man in a position of authority in the detective work. The other characters include the suspects he has to deal with. Each suspect has their own story and motives, and through his interactions with them, we see more of the complex social fabric of the town.
Since we don't know what 'heat a novel' is really about, it's impossible to say who the main characters are. They could be anyone from scientists studying heat in a fictional world, to people living in a very hot region, or characters involved in a 'heated' relationship or conflict.
Without having read the 'Heat in the Hamptons Novel', it's impossible to accurately name the main characters. But they could be wealthy socialites, local business owners, or perhaps some artists or outsiders who get caught up in the Hamptons' unique social web.
I don't know specifically as I haven't read the novel. But typically, main characters are those who drive the story forward, they could be people with strong personalities or unique circumstances in the context of the 'heat of the day' setting.
Without having read the book, it's impossible to say for sure. But it might have a protagonist who is in search of both heat (maybe in the form of a burning ambition) and light (like the truth). There could also be supporting characters who either help or hinder this search.
I'm not entirely sure without reading it more closely, but typically there would be characters who are central to the story's development, like a female protagonist perhaps.
In a 'heat wave novel', the main characters might include an elderly person who has memories of past heat waves and can offer wisdom on how to deal with the current one. There could also be a young activist who is determined to raise awareness about the causes and effects of heat waves and is leading a community - based effort to adapt. And perhaps a government official who is struggling to allocate resources to deal with the heat wave - related problems.
The themes include identity. The black detective has to constantly assert his identity and worth in a world that tries to marginalize him. Also, there's the theme of community. The novel shows how the actions of individuals can affect the whole community, both positively and negatively.
