She actually dedicated the story to Bob Dylan, because his song "It's All Over Now, Baby Blue" inspired her to write it, and I think the story was also inspired by a kidnapping, which seems to be a prominent theme for the BSB album as a whole (with a few exceptions, perhaps), specifically in "So Come Back, I Am Waiting."
This song has always reminded of Joyce Carol Oates's "Where Are You Going, Where Have You Been?"
