A children’s book set in Berlin
One of the insights for Emil and the Detectives that Wikipedia provides is that,
The most unusual aspect of the novel, compared to existing children’s literature at the time, was that it was realistically set in a contemporary Berlin peopled with some fairly rough characters, not in a sanitized fantasy world; also that it refrained from obvious moralizing, letting the characters’ deeds speak for themselves.
About Emil and the Detectives
So, what’s the story? Emil is on a train for the first time by himself. Other passengers find him very friendly. He eventually doses off and, when he wakes, he notices that the money he had in his pocket is gone. He thinks he knows who took it and enlists in a little help from his friends to find the thief.
