* The name is misspelled. Perhaps you're thinking of an author with a slightly different name. Try double-checking the spelling.
* The author is relatively obscure. If the author isn't well-known, you might have difficulty finding information about their works.
* The author might use a pen name. This could be a pseudonym, and finding the real name could help uncover their writing.
To help me find the author you're looking for, could you please provide more information? For example:
* Any other details about the author? Do you know their full name, nationality, or any specific genres they write in?
* Do you remember any titles of their works?
* Where did you encounter the name H.W. Grosette? Was it a book, online article, or somewhere else?
With more information, I might be able to help you find the author and their works.
