A new mystery series set in Paris introduces intrepid detective Aime Leduc. It is November 1993 and the French prime ministerial candidate is about to sign a treaty with Germany that will severely restrict immigration, reminiscent of the Vichy laws. Aime Leduc is approached by a rabbi to decipher a fifty-year-old encrypted photograph and place it in the hands of Lili Stein.
When she arrives at Lilis apartment in the Marais, the old Jewish quarter of Paris, she finds a corpse in whose forehead is carved a swastika. With the help of her partner, a dwarf with extraordinary computer hacking skills, Aime is determined to solve this horrendous crime. Then more murders follow.
Her search for the killer leads her to a German war veteran involved in the 1940s with a Jewish girl he was supposed to send to her death. It takes Aime undercover inside a neo-Nazi group, where she must play a dangerous game of current politics and old war crimes. Many of the older Jews in the Marais are afraid and prefer to leave the past alone, but the horrible legacy of the death camps and the words never forget propel Aime to find out the true identities of the criminals past and present.
