Exploration Stage: Clock Tower
From: Janko
Description: You still can't believe that I am from the von Oben family? If so, how do you explain that you know so much about this clock tower? For example, there is other evidence that Tilly and I were close. Among the many books I have is an adventure novel. Could you search for that with me?
Completed: Oh, there it is! This was the first gift I gave Tillie, and my father told her not to read it. The reason was that he did not want her to have "nonsense fantasies". So I tore out the pages in secret, hid them in a feather and gave them to my sister piece by piece.
