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.
As
Langdon deals with the events into which he has been thrust, Mal'akh destroys
the Smithonsonian-sponsored laboratory of Dr. Katherine Solomon, Peter's
younger sister, where she has conducted experiments in Noetic Science, in the
process ambushing and almost killing Katherine in a cat-and-mouse chase, but
Katherine manages to escape and meet up with Langdon and Bellamy. Mal'akh then
destroys all of Katherine's research. Eventually, when cornered by the
authorities, Bellamy is forced to give himself up while Langdon and Katherine
escape. Both are later apprehended by Sato's team. Following clues regarding
Mal'akh's previous identity as Peter Solomon's psychiatrist, Dr. Christopher
Abaddon, Sato allows Langdon and Katherine rush to his mansion to confront him,
but Mal'akh ambushes them and murders their CIA escort. Meanwhile, as he is
being interrogated by Sato, Bellamy expresses belief that Sato is working with
Mal'akh, but Sato assures Bellamy that she is also pursuing Mal'akh in the
interests of national security, and displays a piece of evidence that visibly
shocks Bellamy.
Mal'akh
places Langdon into an airtight sensory deprivation tank, where he interrogates
Langdon by slowly filling the tank with liquid. He is able to convince Langdon
to unlock the code at the Pyramid's base, but continues to fill the tank until
Langdon apparently drowns. Mal'akh then ties Katherine to a chair and inserts
an open-ended transfusion needle into her arm, and leaves her to bleed to
death, and then flees with a weakened and wheelchair-bound Peter Solomon to the
Temple Room of the Scottish Rite's House of the Temple. He uses the threat of
not calling an ambulance for Katherine as further coercion for Peter's
cooperation. Sato leads a team of agents to the mansion after Langdon and
Katherine's escort fails to check in, and are able to save Katherine's life.
Langdon is revealed to have survived, due the "water" in the tank
actually being breathable oxygenated liquid, and the tank being a device for
meditation. Sato, Langdon, and Katherine race to the House of the Temple where
Mal'akh threatens to release a heavily edited video showing government
officials performing secret Masonic rituals (the same video that Sato showed to
Bellamy), which without context, appears highly disturbing. Mal'akh forces the
Word—the circumpunct—out of Peter and tattoos it on his head on the last
portion of unmarked skin on his body. Mal'akh then orders Peter to sacrifice
him, as he believes that it is his destiny to become a demonic spirit and lead
the forces of evil. When Peter claims that he will do so without hesitation to
avenge his son and mother, Mal'akh shocks Peter by revealing that he is
actually Zachary Solomon himself, having conspired with the prison warden to
fake his death by disfiguring the body of another inmate beyond recognition (at
the same time, Langdon, Katherine and Bellamy discover several photos of
Zachary in Greece after his supposed death that show his gradual transformation
into Mal'akh). Tears in his eyes, Peter prepares to stab Zachary, but
ultimately cannot bring himself to do so, and drops the knife just as Langdon
arrives and tackles him. Director Sato arrives at the Temple in a helicopter,
which smashes the Temple's overhead glass panel, the shards of which fatally
impale Zachary. The CIA then thwart Zachary's plan to transmit the video to
several leading media channels using an EMP blast, disabling a cell tower in
the network path leading from Zachary's laptop computer. Langdon and Katherine
then share a tearful reunion with Peter, and mourn Zachary's death. Zachary, in
soul form, is only briefly able to lament his body's mutilation before he is
presumably dragged down to Hell.
Later
on, Peter informs Langdon that the circumpunct Zachary tattooed on his head is
not the Word. He also informs Katherine that made back-ups of all of her noetic
research data on his own computer, meaning her research can continue. Deciding
to take Langdon to the true secret behind the Word, Peter leads him to the room
atop the Washington Monument and tells him that the Word—a common Christian
Bible, the "Word of God"—lies in the Monument's cornerstone, buried
in the ground beneath the Monument's staircase. Langdon realizes that the
symbols on the pyramid's base spelled out the words Laus Deo which translate to
Praise God. These words are inscribed upon the small aluminum capstone atop the
Monument, which is the true Masonic Pyramid.
Peter
tells Langdon that the Masons believe that the Bible is an esoteric allegory
written by humanity, and that, like most religious texts around the globe, it
contains veiled instructions for harnessing humanity's natural God-like
qualities—similar to Katherine's Noetic research—and is not meant to be
interpreted as the commands of an all-powerful deity. This interpretation has
been lost amid centuries of scientific skepticism and fundamentalist zealotry.
The Masons have (metaphorically) buried it, believing that, when the time is
right, its rediscovery will usher in a new era of human enlightenment.
