Congratulations! You have solved the mystery. You have found the trap door under the rug beneath the desk in the library. The room was once an old fallout shelter. We still keep a supply of food stocked here in the event of tornados and other emergencies. You may wish to email me and tell me you solved Mystery#1 by using the code word APPLE 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.]
