Once again, Harper manages audience expectations by exploring the idea that the “Falk” on Ellie’s note actually referred to Erik Falk, the father of protagonist Aaron Falk.

This passage hints at a potential wedge in Aaron Falk and Erik Falk’s relationship, where Ellie’s death prevented either of them from being able to fully trust the other.
