Where is Holden as he narrates the story?

Even though Holden is never specific about where he is while narrating the story, the first page and the last page of the novel provide clues that Holden is undergoing treatment for a mental breakdown in a psychiatric hospital near Hollywood, California. As the novel opens, Holden says, “I’ll just tell you about this madman stuff that happened to me around last Christmas just before I got pretty run-down and had to come out here and take it easy.” At the close of the novel, he ends his narration saying, “I could probably tell you what I did after I went home, and how I got sick and all, and what school I’m supposed to go to next fall, after I get out of here, but I don’t feel like it.” By bookending the novel with these statements, Salinger reveals that Holden is narrating from a mental health facility.
