The protagonist of a story is the main character, who traditionally, undergoes some sort of change. He or She must usually overcome some opposing force. In this story, the protagonist and main character is the narrator Christopher Boone, who wishes to solve the murder of Wellington and finds another mystery as a result.
The antagonist of a story is the character that provides an obstacle for the protagonist. In this novel, the antagonist is the world removed from his routine: that is, the everyday world of chaos, disorder, absence. The initiator of chaos is the murderer of Wellington, a mystery Christopher chooses to solve. This turns out to be Christopher's father, Ed Boone, who brings further turmoil with his deception regarding the death of Christopher's mother.
The climax of a story is the major turning point that determines the outcome of the plot. It is the point to which the rising action leads. Sometimes, as in this case, the author will create a n explosive and attention grabbing scene for the climax. Christopher discovers his mother isn't dead, as his father claimed, and that he killed Wellington.
The outcome is also known as the resolution or denouement, this is the place in the plot where the action is resolved or clarified. The outcome of this novel is unusual. Typically, the protagonist prevails and the antagonist suffers: the good guy wins and the bad guy loses. Christopher goes to London to be with his mother and they return to Swindon, where his father slowly regains the trust of his son.
