The Invisible Man has many possible themes. There are multiple examples of different themes in the novel. Most of them can almost fall under the same idea. The main theme for the novel is how excessive greed can have unintended consequences. The main character, Griffin, goes mad with the power of being invisible. It gets to the point that he is not even trying to just stay hidden anymore, he is just trying to cause as much mayhem in the country as possible.
One of the first instances of greed is when he starts to take advantage of Mrs. Hall, the woman who owns the Coach & Horses Inn. Mrs. Hall mainly feels bad for him at first because she thinks he is very hurt or injured in some sort of way due to him wrapping his head up. Griffin keeps her away from his room at times so he can conduct his experiments without anyone knowing. Whenever he damages anything in the inn he just tells Mrs. Hall to put it on his bill. Later in the novel we learn that he has stolen all of the money he has, but while being invisible he rarely has a reason to use the money. Griffin giving extra money to Mrs. Hall when he breaks or damages things is one of the only times in the novel he can actually put use to the things he has stolen.
The town starts to wonder who Griffin is and where he came from. Many rumors start to float around the town. Mrs. Hall even says to others he is not that bad of a man. When protecting his secret all the time, he is always on his guard. This creates an uneasy feeling for everyone around him. Finally a man named Mr. Cuss asks to interview Griffin. When Mr. Cuss is interviewing Griffin, Griffin takes his hand out of his pocket. Mr. Cuss can now see that there is no arm in the sleeve. Griffin then leans forward and pinches Mr. Cuss’s face.
Griffin is slowly growing mad with power. At this point he is not even trying to survive or just try to cause chaos. He is just flat out doing unintelligent things that will get him caught. This relates back to the theme because Griffin thinks he can get away with whatever he does because he is invisible. He’s getting greedy and he will soon pay for what he is doing.
Soon all over the town burglaries start to occur. In the middle of the night the people who are being robbed can hear someone in their house, but when they search around there is no one to be found. So since the incident with Mr. Cuss and all these burglaries, the townspeople start to point fingers are Griffin. The Hall’s even send a person after Griffin to perform an exorcism thinking he is a witch or something that has to do with magic.
After a while Griffin does not pay his bill at the inn for a few days, Mrs. Hall wants an explanation for it. He even tries to give her more money but she refuses it. Now earlier in the novel him paying for his rent with the money he stole was only real use for the money. Now that he cannot even give Mrs. Hall any more money, he has no use for the money he has stolen whatsoever. After she asks for an...
