Book Hides Valuables

Congratulations for finding my secret storage compartment! The book that you found here is not just an ordinary book. Opening it reveals yet another of my hidden storage areas for valuables. You may wish to email me and tell me that you solved Mystery#4 by using the code word DAYTIME as the text and subject of your message.

[When you have accumulated all four code words send them to me all together in the text area of an email. In the subject area write CERTIFICATE OF COMPLETION REQUESTED. Be sure to print your name the same way you want it printed on your certificate.]
