Any topic (writer’s choice)

Hi! the research question is :
Read Poes “The purloined letter” through Freud. How are Freudian psychoanalysis (as a literature) and its concepts understandable through the short story?

I need to write about freuds idea of masochism, ego, id ego and super ego as well as the idea of the conscious and unconscious mind and relate it to the purloined letter. i have written about 1500 words already but it feels very incomplete so please develop my points thanks!
I am attaching some texts that were provided in class as well as some online research i did (copy pasted) and the part of my essay i have written. Feel free to be creative with it.
