What has the author John F Pile written?

It seems you're asking about an author named John F Pile. I was unable to find any information about an author with that exact name.

It's possible:

* The name is slightly different: Perhaps there's a small variation in the spelling, like John P. Pile or a middle name.

* They are not a widely published author: If they've written independently or in niche genres, their work might not be easily searchable online.

To help me find this author, could you tell me:

* Any other information about them: Do you know what they write about? Any other works they might have published?

* Where you encountered their name: Was it in a book, article, or online source?
