* The name is misspelled. Perhaps you meant a different name? Try checking for variations of the spelling.
* The author is relatively unknown. They might be a self-published author or write in a niche genre.
* The author uses a pen name. It's possible that "Frank Staff" is a pseudonym.
To help me find the author you're looking for, could you please provide more information? For example:
* What kind of books do you think they write? (genre, subject matter)
* Do you know anything else about them? (time period they wrote in, nationality, etc.)
* Can you remember any specific book titles?
With more information, I might be able to help you find the right author.
