Every British schoolchild learns the story: the Great Fire of London started in Thomas Farriner's bakery on Pudding Lane in the early hours of Sunday, September 2nd, 1666. One careless spark. One bakery. Five days later, 13,200 houses destroyed and 87 churches reduced to ash.

But here's what they don't teach: even in 1666, people weren't convinced it was an accident.

In The Monument, my protagonist discovers evidence that the Fire had three separate ignition points, deliberately coordinated to maximize destruction in specific zones. That's fiction. But the historical uncertainty? That's real.

What We Actually Know

The Fire definitely started at Farriner's bakery around 1:00 AM. Farriner, the King's baker, always maintained his ovens had been properly extinguished. His maid testified that she was the last person awake and checked everything before bed.

Yet somehow, around one in the morning, fire broke out.

The exact cause was never definitively established. The official inquiry blamed "the hand of God" and "strong winds" for the catastrophic spread. But that explanation satisfied no one in 1666, and it shouldn't satisfy us now.

Because the Great Fire didn't spread like a normal fire.

The Burn Pattern That Doesn't Make Sense

Fires spread predictably. They follow wind direction, consume fuel, and leave patterns that fire investigators can analyze even centuries later.

The Great Fire spread east and north from Pudding Lane, driven by strong easterly winds—this matches expectation. But contemporary accounts describe burn intensity that varied dramatically across the city. Some areas experienced total destruction down to foundation stones. Others, equally wooden and densely packed, suffered moderate damage.

Samuel Pepys, who documented the Fire in his famous diary, noted something strange: "The fire taking hold in several places, farther than we expected."

That phrase—"taking hold in several places"—haunted me when researching The Monument.

Robert Hooke, Christopher Wren's colleague and fellow scientist, wrote in his papers about "suspicious circumstance of flame appearing in diverse quarters near simultaneously."

These aren't crackpot conspiracy theorists. These are the most credible observers of the period, noting something didn't fit the official narrative.

The Contemporary Accusations

In 1666, Londoners immediately suspected arson. Mobs attacked foreigners, particularly the French and Dutch (England was at war with both nations). A French watchmaker, Robert Hubert, was arrested, tried, and hanged for starting the Fire—despite being provably not in London when it began.

Parliament conducted an investigation. They questioned witnesses. Examined evidence. And concluded... nothing definitive.

The official monument to the Fire (the 202-foot column designed by Wren) originally included an inscription blaming Catholic conspirators. That inscription was later removed, not because it was proven false, but because it was politically inconvenient.

Think about that: the memorial to England's greatest disaster originally accused specific groups of deliberately setting it. That's not how you commemorate an accident.

Why Three Ignition Points?

In The Monument, I propose that if you wanted to destroy specific areas of London while maintaining plausible deniability, you'd start multiple fires in a coordinated pattern.

Start point one (Pudding Lane) at 1:00 AM. Let it establish. Then start point two (perhaps Milk Street) around 1:15 AM, when the first fire has drawn attention. Point three (maybe Gracechurch Street) at 1:20 AM.

Each fire close enough to eventually merge, but far enough apart that in the chaos, confusion, and poor record-keeping of the period, no one could definitively prove they started separately.

Modern fire investigation could identify this pattern through burn progression analysis—examining which areas burned first, hottest, and how the fire moved. But in 1666? Impossible to prove.

And here's the crucial thing: we don't have good enough records to disprove it.

Contemporary maps of fire progression are inconsistent. Eyewitness accounts conflict. The investigation was politically compromised. And Londoners immediately suspected conspiracy—which means even at the time, the single-origin story wasn't convincing.

The Property Acquisition Evidence

What we know for certain: after the Fire, specific families acquired massive property holdings in specific zones of London.

City records (which do survive) show that the Fairchild, Pembroke, Ashton, and Grey families (fictional names in my novel, but representing real consolidated interests) purchased or leased over 260 properties in the immediate aftermath.

Opportunistic investment? Absolutely. The distressed property market after a disaster creates opportunities.

But the pattern of acquisitions is interesting. The properties cluster in areas that burned most completely—not moderately damaged zones, but areas of total destruction where original ownership claims were hardest to establish.

It's circumstantial. It's suggestive. It's not proof.

But it's exactly the kind of pattern that makes historical fiction writers ask: what if?

Why We'll Never Know For Sure

The Great Fire occurred 358 years ago. Physical evidence is gone. Witnesses are long dead. Records are incomplete or compromised by political interests.

Modern investigative techniques—forensic fire analysis, burn pattern reconstruction, chemical residue testing—can't be applied to a disaster that happened three and a half centuries ago.

Which means the question remains genuinely open: was the Great Fire of London an accident, or was it arson?

Most historians lean toward accident, compounded by wooden construction, narrow streets, and strong winds. And that's probably right.

But "probably" isn't "definitely."

And in the space between probability and certainty, fiction finds its most compelling questions.

The Fiction Built on Uncertainty

The Monument doesn't claim to solve this historical mystery. It's a thriller that asks: what if someone in 1666 knew the truth and was smart enough to document it in a way that could survive centuries?

Christopher Wren was a genius—mathematician, astronomer, architect, scientist. He rebuilt London after the Fire. He had access to property records, burn patterns, and the political inner workings of Restoration England.

If anyone could have encoded evidence in architecture, it was him.

If anyone would have recognized that proof couldn't be verbal testimony or written documents (too easily destroyed), but had to be something physical, permanent, and provable through geometry and mathematics, it was Wren.

That's the premise. That's the "what if."

Not that it happened—but that it could have happened. And that maybe, just maybe, someone today could prove it.

What The Historical Record Really Shows

The honest answer to "Was the Great Fire deliberately set?" is: we don't know.

The honest answer to "Could there have been three coordinated ignition points?" is: possibly.

The honest answer to "Could Wren have documented a conspiracy architecturally?" is: surprisingly plausible.

History is full of uncertainties. Fiction explores them.

And sometimes, the best thrillers are built on the questions historians can't answer.
