When will Pseudonymous Bosch come out with his 4 book?

There's a bit of a misunderstanding! Pseudonymous Bosch isn't a real person, but a pseudonym used by the author James Ponti. The "pseudonymous" part is part of the character he created for the "Secret Series" which features the character of Mr. E.

While James Ponti has written many books, the Secret Series currently has three books:

* The Secret Series #1: The Name of This Book Is Secret (2006)

* The Secret Series #2: The Secret of the Secret Series (2008)

* The Secret Series #3: The Third Secret (2010)

There are no confirmed plans for a fourth book in the "Secret Series" at this time.

However, James Ponti continues to write! You can check out his other books and his website for the latest news: [https://www.jamesponti.com/](https://www.jamesponti.com/)
