It's possible that:
* There's a typo: Double-check the name for any errors. Maybe it's "P.E. Biggar," "P.E. Bigger," or something similar.
* The author uses a pen name: Could "P E Biggar" be a pseudonym?
* The author is less known: Perhaps they've written niche works or haven't published extensively.
To help me find the author you're looking for, please provide:
* More details about their work: What genre do they write in? What are the titles of their books?
* Any other information: Where did you encounter this name?
With more information, I might be able to track down the author you're seeking.
