Codes, ciphers and masons.............oh my..............


Ben, Abigail, and Riley go to Patrick's home. Despite Patrick's protests, Ben and Abigail start to review the Declaration, and find a Ottendorf cipher written in invisible ink on its back. The encrypted message references the Silence Dogood letters written by Benjamin Franklin, which were owned by Patrick, but he recently donated them to the Franklin Institute. Ben, Abigail, and Riley use schoolchildren to acquire the key words from the letters, with a message pointing them to the bell tower of Independence Hall where the Liberty Bell was originally located. There, they find a hidden cache with a pair of spectacles with multiple colored lens, which when used to read the back of the Declaration, reveals a clue in an older area of New York City.
