I'm sorry, but I do not have information about an author named Iris Beaglehole. It's possible that there may be a typo in the name or she could be a less well-known or emerging author, and therefore, not much information is available about her in prominent databases. If you meant the New Zealand ethnologist and writer, Ernest Beaglehole, or another author, please provide the correct name, and I'd be happy to give you a short description. Alternatively, if Iris Beaglehole is indeed the author you're inquiring about, the best way to gain information about her might be through a focused web search or by looking into specific publications or bibliographic databases where her works are listed.
