My novel is "written" by my main character as a way to prove his innocence (to crimes he did commit) and purposely twist the story in his favor. I have done a little research on unreliable narrators and from my understanding it can be written in first-person or third-person limited narrator. Throughout the story, I wanted to slip in clues to his unreliability. But why in the world would my main character slip clues of his unjust deeds into a story which is suppose to assert his innocence? Would this story work in first-person or do I need to write in third-person limited? Could I start in first-person and then switch to third for the majority of the story with brief interruptions of first-person? Any help would be appreciated.
