An encrypted message?  I bet there is actually one on the back of the Dec. of Indep............of course the American Illuminati are hoping no one has the balls to take said document from its case in the Nat. Archives..................



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. They become aware that Ian and his agents have been following them, and the group splits up. Ben is arrested and interrogated by the FBI, while Abigail and Riley attempt to flee with the Declaration but lose it to Ian. Abigail is able to convince Ian to help them rescue Ben from the FBI in exchange for the next clue. Ian agrees, and arranges a meeting at the USS Intrepid during which they engineer Ben's escape.
Ian then returns the Declaration and demands Ben provide the next clue, but Ben remains coy. Ian reveals they have captured Patrick, coercing Ben's cooperation, and directing them to the Trinity Church. Inside, they find a passage that leads deep underground. A room at the bottom is lit by a single lantern, which Patrick asserts refers to Paul Revere's Ride—a clue pointing to the Old North Church in Boston. Ian and his men ditch Ben, Abigail, Riley and Patrick and race to Boston, unaware that the clue was fake. Ben opens a secret door by an engraving of the all-seeing eye. Inside, they find a notch which the pipe from the Charlotte fits, opening onto a large chamber containing the national treasure, as well as a secondary passage to the surface. Once out of the church, Ben contacts Sadusky, and learns he is a Freemason; Ben returns the Declaration and the location of the treasure in exchange for their names being cleared of stealing the Declaration. Ben also informs Sadusky of his bluff to Ian, and the FBI are able to ambush Ian and his men and charge them with kidnapping, attempted murder, and trespassing on multiple government properties.
Later, Ben and Abigail have started a relationship, while Riley is somewhat upset that Ben turned down the 10% finder's fee for the treasure and accepting a much smaller amount that still has netted them all significant wealth.
