Nono is the son of the world's greatest police inspector and has been trained since birth in the finer arts of sleuthing. So when a train trip to stay with his terribly boring Uncle Shmuel morphs into a rollicking mystery-solving adventure, Nono couldn't be more thrilled. And when he meets up with the notorious criminal Felix Glick, his father's arch nemesis, he finally gets the chance to prove that he has what it takes to be a great detective. Wearing disguises and on the run from the police, Felix and Nono head to the French Riviera, where Felix introduces Nono to the seductive Lola Ciperola. Now with only twenty-four hours to go before his Bar Mitzvah, Nono has to complete his high-stakes mission - while also confronting the mystery of his own identity and the truth about the mother he has never known.
