More thrilling than in this book, one can hardly speculate about the end of childhood. Spiegel Spezial Nono will turn thirteen in a few days. A special date, as he will celebrate his Bar Mitzvah, his entry into the Jewish community. But before the big celebration can take place, Nono finds himself alone on the train from Jerusalem to Haifa. His uncle is expecting him to give Nono the final instructions for the grand event. However, everything takes a different turn. During the journey, two men enter his compartment: they are handcuffed together, a prisoner and his guard, as Nono observes. But why are the two behaving so strangely? Nono is sweating profusely. Just as suddenly as they appeared, they disappear again. On the seats, they leave behind a letter addressed to Nono. There are two senders: Nono's father and his wife.
