Essays / Key incidents and characterisation in "The Curious Incident ..." [6]

Discussion on"The curious incident of the dog in the night time"by a different author

topic: Discuss how the novel would be different if it were written by another character, for example Ed Boone or Siobhan, or in a third person omniscient voice. What would be lost with such changes and what would be gained.

I really need help with this in all departments eg. what would be some of my topic sentences to start each paragraph and so on, any ideas and help would be much appreciated :)
