I'm not sure without actually reading the story, but it's likely that the main characters would be the parents of the son who has died. They would be central as they are the ones most directly affected by the tragedy.
In many short stories, there are often characters that represent different ideas or values. In 'Death by Landscape', there might be a character who represents the allure of the landscape, always drawn to it and perhaps a bit naive about its potential dangers. Another character could be more cautious and try to warn others about the risks associated with the landscape. These different character types would interact and their conflicts or agreements would shape the story.
One possible analysis could be that it explores the profound grief of a parent. The death of a son is often a shattering event, and the story might focus on how the characters deal with the loss, the emotions that follow like sorrow, anger, and perhaps even guilt.
I don't know as the name 'the son short story' is quite general. It probably has the son as a main character, and perhaps his parents or siblings.
Since I don't know the story well, it's hard to say exactly. But there might be a driver, who could be either the victim or the cause of the 'death car' situation. There could also be other people related to the events around the car, like passengers, witnesses, or investigators.
There could be a family at the center of the story. Maybe a father who is trying to protect his family from the plague. A mother who is taking care of the sick children. And perhaps a young protagonist who is observing all the chaos and changes around them, learning about life and death in the face of the Black Death.
I'm not familiar with this short story, so I can't say for sure who the main characters are. But they could be the victim, the people close to the victim like family or friends, and perhaps the ones involved in the events leading to the death such as suspects or witnesses.
In 'A Death in the Desert Short Story', the main character might be the victim of the death. Their actions, or perhaps their misfortunes, are what the story is centered on. There could also be other characters like a traveler who stumbles upon the scene of the death or a local inhabitant who has some knowledge about the area where the death occurred. These characters would play important roles in uncovering the story behind the death.
The main character is the prince. There are also the nobles who are with the prince in the abbey trying to escape the Red Death.
There may be his superiors or colleagues in the story. Since it's about a clerk, those he works with or under would play important roles. They could be the ones who influence his situation and perhaps contribute to the events leading to his death, like through overwork or social pressure.
The main characters are the man who makes Death his godfather and Death itself.
