November 1989: Aimée Leduc is in her first year of college at Paris’s preeminent medical school. She lives in a 17th-century apartment that overlooks the Seine with her father, who runs the family detective agency. But the week the Berlin Wall crumbles, so does Aimée’s life as she knows it. First, someone has sabotaged her lab work, putting her at risk of failing out of the program. Her father takes off to Berlin on a mysterious errand and asks Aimée to help out at the detective agency while he’s gone. But the case Aimée finds herself investigating --- a murder linked to a transport truck of Nazi gold that disappeared in the French countryside during the height of World War II --- has gotten under her skin.
