Quick Note: Looking For Information

I'm looking for any information on the creators of the "Arsole Fantüme" novels, a pair of writers who used the names "Marcel Maurice" and "Pierre." I know a new translation of "AF" has been recently published, but other than that, my research has dead-ended.

This is just a quick note to get myself and my request out there. I'm an author and very much interested in writing an article or perhaps something longer on these obscure writers' lives.
