Alternatively, "Borghild" is a Norwegian name, so maybe there's a Borghild Dahl, but I can't recall any notable figure by that name. The user might have made a mistake. Since the user is asking for a paper, perhaps they need an academic paper or a literary analysis. Since the query is in Chinese, maybe the user is non-native and had a typo. Let me confirm if there's a known person named Borg Hild Dahl. A quick search shows no results. So likely, it's a typo for Roald Dahl.
