It's possible:
* The name is slightly incorrect. Perhaps you are thinking of a different name, like Ernest Parker or Walter Ernest.
* The author published under a pseudonym. Many authors use pen names, so the name you're looking for might be a pseudonym.
* The author is relatively unknown. There may be less famous authors who have written under this name.
To help me find the author you're looking for, please provide any additional details you have:
* Any other books they might have written.
* The genre of their writing.
* The approximate time period they were writing.
* Any specific books you've read by them.
With more information, I can help you track down the author you're interested in.
