Langdon is then met by Trent Anderson, head of the Capitol police, and Inoue Sato, the head of the CIA's Office of Security. Sato claims that Mal'akh poses a threat to the national security of the US, and that his capture is more important than Peter's rescue, although she refuses to elaborate. Examining Solomon's hand, they discover a clue leading them to Solomon's Masonic altar in a room in the Capitol's sub-basement, where they find a small pyramid lacking a capstone, with an inscription carved into it.

Sato then confronts Langdon with the security x-ray taken of his bag when he entered the Capitol, which reveals a smaller pyramid in the package Langdon brought in response to the request by the kidnapper posing as Solomon. Langdon explains that he was unaware of its contents, but Sato, dissatisfied with this, attempts to take Langdon into custody. Before she can arrest him, however, she and Anderson are assaulted by Warren Bellamy, the Architect of the Capitol and a Freemason, who then flees with Langdon during the melee. He later explains to Langdon that he too has been in contact with Mal'akh, and wants Langdon's assistance in rescuing Peter.

Mal'akh is revealed to be a Freemason with tattoos covering almost his entire body. He infiltrated the organization in order to obtain an ancient source of power,^[9] which he believes Langdon can unlock for him in return for Peter Solomon's life. Several chapters also delve into Mal'akh's history with Peter Solomon: many years ago, Peter bequeathed a large sum of inheritance money to his rebellious son, Zachary, who then fled the Solomon household and led a reckless life in Europe until he was arrested and imprisoned in Turkey for smuggling drugs. Peter flew to Turkey, but decided to have Zachary extradited in a week's time instead of getting him out immediately in order to teach him a lesson. But apparently, Zachary was murdered by his cellmate, who got his hands on Zachary's fortune and fled to Greece to lead a luxurious life under the name Andros Dareios. Dareios, however, soon grew tired of his life. Apparently having spoken with Zachary about Solomon's life as a Mason, Dareios broke into Solomon's home to find the pyramid, but accidentally killed Peter's mother, Isabel, and was in turn shot and left to fall into a frozen river by a vengeful Solomon himself. Surviving the fall, Dareios nursed himself back to health, covered his scars and eventually his entire body with tattoos and set off on a mission to infiltrate the Freemasons and gain access to their secrets, adopting the name Mal'akh.
