Direct answer: The phrase you provided in German, “kammer des schreckens welcher teil,” translates to “Chamber of Secrets which part” in English. It seems you’re asking which part or installment of the Harry Potter series corresponds to the Chamber of Secrets. Context and clarification:

• In the Harry Potter series, the Chamber of Secrets is the title of the second book and film: Harry Potter and the Chamber of Secrets. It is not a separate “part” within a larger book or story; it is the name of the second installment in the series.

If you meant something else:

• If you’re asking which part of the book or movie contains the Chamber of Secrets within the story, it appears in the second year at Hogwarts and is central to the plot of the second book/film.
• If you’re looking for details about the Chamber of Secrets itself (its origins, how it opens, who is involved), I can summarize that as well.
