Sealed · Book III
Hidden in Plain Sight · Book III In production
Written in the Open
Real codes, ciphers and hidden messages in old texts, art, music and buildings: the certain ones, the disputed ones, the hoaxes, and how to tell them apart.
This book is sealed. Its title and promise are above. The research that goes into it is being published as it is checked, and the book unseals when it is ready. If you want to know the day, the Registry is the place.
