Pseudonymous Bosch (edit name/settings)

Pseudonymous Bosch is the nom de plume of the author of the "Secret Series" of children's books. (The pseudonym is a pun based on the name of the artist Hieronymus Bosch.)

According to the 'authors bio':
"Pseudonymous is an avid fan of chocolate. Especially the rich and creamy kind. And he's an author, of course. He also likes cheese, and hates mayonnaise with a passion, and likes chess too. 'But is that all?' People ask, people who clamor for secrets, answers, and secret answers. Of course that's not all! Pseudonymous Bosch is not a shallow, dilly-dallying nonesuch! He has a life besides chocolate, cheese, chess, and writing.
It's just that nobody really knows what it is.
Also, he could, just possibly, be a character in his book in secret, that is his whole theme, secret.Will he ever reveal his secret?"
