Breakfast. Salinger had a habit of eating thawed peas for breakfast. Along with chain smoking, he regularly drank seaweed tea and relished rifling through a copy of the latest New Yorker, which had published several of his short stories. 
Details:
Unpublished. There are allegedly 5 manuscripts pending publication between 2015-2020. Until now, the only full-length novel he ever published was Catcher in the Rye. Salinger used sticky-dots to mark whether a draft was in progress or complete.
Detail:
Foxhole. Having served as an army Sergeant during World War II, Salinger suffered undiagnosed PTSD from months of combat shock. Returning home, Salinger more and more isolated himself from those around him. He wrote in a wartime correspondence, "I dig my foxholes down to a cowardly depth." It could be inferred that Salinger never did quite get free of the foxhole.
