Paris, July 1999: Private investigator Aimée 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 Aimée to investigate, is it possible Mirko Vladiâة̄ could be alive and in Paris with a blood vendetta? Aimée 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. Aimée chases the few leads she has, and all evidence confirms Mirko Vladiâة̄ 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?
