[3] At the close of the story, Vincent understands his mother's concern, but feels sorry for her solicitous behavior, and expresses depression over the fact she worries so much, particularly over kids who are about to fall off a cliff.
Biographer Kenneth Slawenski provides the key thematic element in “The Last and Best of the Peter Pans”: The story is an intensely personal work that examines what was arguably Salinger’s closest relationship: that with his mother.
“The Last of the Peter Pans” remains the deepest insight into the character of Miriam Salinger, her protective bond with her son, and his conflicted feelings regarding it.
Upon reflection, Vincent dubs her “the last and best of the Peter Pans,” praising his mother's determination to preserve the life and happiness of her remaining children.
Salinger's estate as well as his literary agency, Harold Ober Associates, have stipulated the work will not be published until 2051, per his explicit wishes.
