Reading Background:

• Third book read in 2026! Finished the book on CNY Eve, and a day before my birthday!

• Was not disciplined enough to read, as I turned to mindless social media scrolling on several evenings. Wouldn’t have finished this book as quickly if not for a day of MC (back pain) at home.

• Think I might just stick to finishing up this series before moving on to others.

What I enjoyed about the book:

• The mystery and thrill. They maintained my momentum to keep turning the pages.

• The unfolding events and flashbacks in various settings and timelines were woven seamlessly and smoothly, in a way that I didn’t forget what happened in the other settings, nor did I find the scene transitions jarring.

• The ultimate reveal was shockingly unexpected.

What I found less enjoyable about the book:

• The great potential of the book was not fully realised. The build-up to the climax and development of the side characters as potential suspects were so extensive and thrilling, but the climactic revelation was so fleeting that it felt like the ball was dropped.

• The conversations between characters often felt unnatural, as there was too much info-dumping in forced and clunky expositions, that felt more like the author trying to convince readers of his theories.

• The marrying of Freemasonry and noetic science was fascinating, but it felt like the marriage of the concepts and themes wasn’t executed in a polished manner, despite numerous repetitive and tiresome attempts.

• The highly callous treatment of Trish was nauseating.

My overall thoughts:

• Enjoyable for the thrill, but I felt that several aspects of this book left much to be desired. Overall, I thought that this was a highly decent book, though not as good as the previous two in the series.

• Langdon was invited to the US Capitol, believing he was to give a lecture for his mentor, Solomon, a 33rd-degree Mason. Upon arrival, he found the Rotunda empty, except for Solomon’s severed right hand, which had been tattooed and arranged to mimic the ‘Hand of Mysteries’, pointing up toward the ‘Apotheosis of Washington’.

• A man named Mal’akh informed Langdon that he had kidnapped Solomon and asked that Langdon unlock a source of powerful ancient wisdom (“Ancient Mysteries”), in exchange for Solomon’s life.

• Sato, CIA Office of Security Director, arrived and forced Langdon to assist her in capturing Mal’akh, as he posed a national security threat. 

• Langdon aided Sato to retrieve a stone pyramid from the Capitol’s basement but was rescued by its architect Bellamy, a high-ranking Mason. They fled the Capitol to decipher the pyramid, believing Sato intended to seize it.

• They were joined by Katherine, Noetic scientist and Solomon’s sister, whose lab Mal’akh had just destroyed. Bellamy was captured by CIA agents, while Langdon and Katherine managed to escape in search for Galloway at the National Cathedral.

• Galloway aided both in deciphering the codes of the pyramid and its capstone that Solomon had entrusted Langdon with. They were captured by Sato, but the group split up after receiving a call stating that Solomon is at Mal'akh’s residence.

• Alas, they were tricked and captured by Mal’akh. He placed Langdon in a sensory deprivation tank, tricking him to think he was drowning. Under duress, Langdon decoded the pyramid’s base, which Mal’akh needed to complete his transformation to become a vessel for the ancient wisdom.

• Mal’akh took Solomon to the House of Temple. There he was revealed as Zachery, Solomon’s rebellious son who believed his father had abandoned him in a Turkish prison, and was presumed dead. He had in fact escaped and had transformed his body with tattoos and others. Now, he forced Solomon to reveal to him the “Lost Word”, and to kill him as a sacrifice, that he might complete his transformation. In the end, Solomon didn’t do any of that.

• The CIA arrived by helicopter and smashed the Temple’s skylight and fatally wounded Zachery. They also used an EMP device to destroy Zach’s laptop, preventing a video exposing Masonic rituals to the world. This saved the Mason’s and prominent leaders’ reputations.

• Solomon later brought Langdon to the Washington Monument. He revealed that the “Lost Word” was the Bible, and the final code on the pyramid “Laus Deo” referred to the monument capstone inscription. The true secret of the Ancient Mysteries was not a supernatural power, but rather realising that the Bible and other ancient texts contained coded instructions on unlocking the immense, god-like potential of the human mind, a concept Katherine had been scientifically proving in her Noetic lab.
