The Secret Agent Handbook is a book published by Grosset & Dunlap for Club Penguin. It was released on June 4, 2009. It tells you about Secret Agents. You can also unlock it for book codes and coins. However, as of May 2010, the information in the book was no longer correct, as the PSA was destroyed, so sales have decreased. It does not have any information on Mission 11 or the EPF.
