Analysis
On December 10, 1940, a man named Daniel LeBlanc, living in Saint-Malo, receives a telegraph telling him to return to Paris at the end of the month—and to travel “securely.”
It’s finally explicitly revealed that Daniel LeBlanc is the name of Marie-Laure’s father. This telegram will upset the relatively comfortable existence Daniel and Marie-Laure have set up in Saint-Malo, as again larger forces affect the personal lives of Doerr’s characters.
