Fiction Adaptation- Post Modernism

Even though Post Modernism is not directly to do with my essay I have found learning about it to be interesting and to help me think of ways to look differently at my essay and what I will be writing about.
In general I think my essay needs these aspects;

• Audience 
• Genre 
• Modern Dilemmas 

These will be related to my case study of Poirot and if the integrity of the work is kept or if the adaptation takes away parts of the book that make the story.
