It's possible that you're thinking of a different author with a slightly different name, or perhaps William R. Sickles is an author who hasn't achieved widespread recognition.
To help me find information, could you please provide me with some additional details?
* Is there a specific genre or subject matter associated with the author?
* Do you have any other information about the author, such as a publication date or a specific title?
With more context, I can hopefully locate the information you're looking for.
