Reading Background:

• Fourth book read in 2026! Started this book on my birthday, a few hours after I bought 'The Duke & I' and gave it up after 2 chapters.

• Rushed through this book within 10 days because I wanted to watch the film on Netflix before it was taken down on the last day of the month.

• Didn't manage to read much during CNY as I had hoped to, but still did while travelling to and from work, and on weeknights etc.

What I enjoyed about the book:

• The mystery of Langdon's amnesia, and the thrill of the race to halt the plague kept me turning the pages.

• The theme on confronting overpopulation and resource depletion felt relatable due to my Geography background, and it also felt like a refreshing change from exploring religions and cults in the previous instalments.

• The complexity and realism of the characters of Zobrist and Brooks were enjoyable to reflect upon.

What I found less enjoyable about the book:

• The fact that all characters subscribed to the Malthusian theory. It felt like a missed opportunity to delve deeper into the Malthusianism vs Cornucopianism argument.

• The dialogue in parts of the book, in an effort to present various philosophies on approaching overpopulation, made Langdon seem uncharacteristically dumb.

• The frequent peppering of historical, architectural, artistic and other titbits, whilst interesting, did annoyingly hinder the narrative flow at some points.

My overall thoughts:

• Fresh, relatable, thrilling, and enjoyable. This fourth book felt to me like a definite step up from the third instalment, though Brown's continued efforts to make each of the Langdon books standalone novels resulted in my inability to grow with and love his characters more. Overall, I still found it to be a good book to recommend!

• Langdon awoke in a Florence hospital with amnesia and a seeming gunshot wound to his head. Before he could make sense of his situation, an assassin named Vayentha breached the hospital. Brooks helped Langdon escape to her apartment.

• Langdon found a bio-tube projector in his jacket, displaying a modified version of Botticelli’s ‘Map of Hell’. It pointed to transhumanist and geneticist, Zobrist, who believed radical measures are needed to halt global overpopulation.

• Langdon and Brooks fled authorities and soldiers, deciphered clues in Florence’s art and architecture, and searched for Dante’s death mask in Palazzo Vecchio. They discovered that Langdon himself and his friend Busoni had stolen the death mask (but couldn’t remember it). A riddle on the mask led them to Venice to search for the tomb of a doge.

• The soldiers were actually with WHO, led by Sinskey. Zobrist had created a virus to “solve” overpopulation, and WHO was trying to find it before its scheduled release date. Meanwhile, the Consortium led by the “Provost” was shielding Zobrist from WHO, unaware of his catastrophic creation. Zobrist was ultimately tracked down by WHO, and he had committed suicide.

• Langdon was captured by WHO in Venice, while Brooks escaped. He learnt that he was initially recruited by Sinskey to aid in tracking down the virus left behind by Zobrist. In Florence, while he and Busoni were decoding the death mask, the Consortium had worked with Vayentha and Brooks to fake an “assassination attempt” and cause his “amnesia” to get Langdon on their side. Brooks was also revealed to be Zobrist’s former lover and a devout follower of his ideals.

• However, the Provost, upon viewing a video left by Zobrist, realised that Zobrist had created a global bio-weapon, and eventually allied with Sinskey to stop it being released.

• Final clues pointed to Istanbul, the Hagia Sophia and Basilica Cistern. The team rushed there in hopes of containing the water-soluble bag holding the virus. However, they discovered the bag had already dissolved a week prior, and the virus infection had spread globally.

• The “Inferno” virus was not a lethal plague that killed people, but a vector that altered DNA, rendering parts of the population sterile to halt unchecked population growth. In the end, Brooks worked with Sinskey, WHO, and global leaders to grapple with the irreversible genetic alteration of the human race.
