I just wanted to know if you ever refer to invisible ink in any of your stories? I have to wait 10 or 15 minutes for a secret message to dry for steam session with school age children. I thought I would read this passage if you have one. I am at the Boston Public Library Eileen Whittle ewhittle@bpl.org

Hi. Chapter 14 in Spy School Revolution discusses invisible ink -- as well as how George Washington's spy ring used it during the Revolution.
