'The Strange Case of Dr Jekyll and Mr Hyde'
Once you have a clear understanding of which characters are in a novel, you will understand the plot better.
As a novella, the story gets to the point quickly and the only characters are ones who help to move the story along.
If you can imagine the writer, R L Stevenson, sitting at his desk and planning the best way to tell his story, it becomes easier to see the characters as 'creations' and not 'people'. They do not have lives beyond the pages of the story and it helps you gain marks if you can show you get this when you write about them. One way to do this is to use phrases like: "Stevenson presents the character of Dr Jekyll as...." or: "The writer shows how Hyde is a violent character when he..."
This shows the examiner that you understand that the writer is using his characters to make the story unfold.
You should always refer to your own text when working through these examples. These quotations are for reference only.
