It's possible that:
* The name is misspelled. Perhaps you meant a different author, or there's a slight variation in the spelling.
* The author is not well-known. Authors who are not widely published or who write in niche genres might not have a strong online presence.
* The author uses a pen name. Some authors use pseudonyms, and it's possible that "Corin Redgrave" is a pen name.
To help me find the author you are looking for, please provide:
* Any additional information about the author or their work: For example, do you know what genre they write in? What is the title of a book they've written?
* Any other details that might help identify them: Where did you encounter this name? Did you find it on a book cover, in an article, or somewhere else?
With more information, I can help you find the author you're looking for.
