Paris, July 1999: Private investigator Aimee Leduc is walking through Saint-Germain when she is accosted by Suzanne Lesage, a Brigade Criminelle agent on an elite counterterrorism squad. Suzanne has just returned from the former Yugoslavia, where she was hunting down dangerous war criminals for the Hague. Back in Paris, Suzanne is convinced she's being stalked by a ghost--a Serbian warlord her team took down. She's suffering from PTSD and her boss thinks she's imagining things. She begs Aimee to investigate--is it possible Mirko Vladic could be alive and in Paris with a blood vendetta?
Aimee is already working on a huge case; plus, she's got an eight-month-old baby to take care of. But she can't say no to Suzanne, whom she owes a big favor. Aimee chases the few leads she has, and all evidence confirms Mirko Vladic is dead. It seems that Suzanne is in fact paranoid, perhaps losing her mind--until Suzanne's team begins to die in a series of strange, tragic accidents. Are these just coincidences? Or are things not what they seem?
November 1989: Aimee 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 Aimee's life as she knows it. First, someone has sabotaged her lab work, putting her at risk of failing out of the program. Then, she finds out her aristo boyfriend is getting engaged to another woman. And finally, Aimee's father takes off to Berlin on a mysterious errand. He asks Aimee to help out at the detective agency while he's gone--as if she doesn't already have enough to do. But the case Aimee 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. Her heart may not lie in medicine after all--maybe it's time to think harder about the family business.
Aimee Leduc has always sworn she would stick to tech investigation--no criminal cases for her. Especially since her father, the late police detective, was killed in the line of duty. But when an elderly Jewish man approaches Aimee with a top-secret decoding job on behalf of a woman in his synagogue, Aimee unwittingly takes on more than she is expecting. She drops off her findings at her client's house in the Marais, Paris's historic Jewish quarter, and finds the woman strangled, a swastika carved on her forehead. With the help of her partner, Rene, Aimee sets out to solve this horrendous murder, but finds herself in an increasingly dangerous web of ancient secrets and buried war crimes.
