It's possible that:
* The name is slightly different: Perhaps you're thinking of an author with a similar name, like George Hervey or Frederick Hervey.
* The author is less known: The author might be a lesser-known writer or have written in a specific niche.
* The author's works are published under a different name: Some authors use pseudonyms or pen names.
To find the specific author you're looking for, please provide any additional information you might have, such as:
* The genre of the book: Is it fiction, non-fiction, historical, etc.?
* A brief description of the book: What is the book about?
* Any other details: Do you know the year of publication or any characters/themes featured in the book?
