Paris, August 31, 1997. The City of Light, usually a symphony of romance and glamour, turned into a nightmare for one of the world’s most beloved figures. Princess Diana, the People’s Princess, had slipped away from the Ritz Hotel in a sleek black Mercedes S280, hoping to evade the relentless paparazzi swarm. Beside her sat Dodi Fayed, her companion and heir to an Egyptian fortune, while bodyguard Trevor Rees-Jones buckled up in the front passenger seat. Behind the wheel was Henri Paul, the hotel’s deputy security manager, who promised a swift, safe escape through the labyrinthine streets toward Dodi’s apartment.

What followed was chaos captured in flashes—literal and metaphorical. The Mercedes roared through the Place de la Concorde, engines revving against the pursuit of seven white Fiat Unos and motorbikes, their drivers hungry for the shot that could make headlines. At 12:23 a.m., as the car plunged into the Pont de l’Alma underpass, disaster struck. Paul lost control at over 65 mph—more than double the speed limit—clipping a white Fiat Uno, swerving wildly, and slamming headlong into the 13th concrete pillar. The impact was catastrophic: the Mercedes crumpled like tin foil, its roof shearing off against the unyielding structure. Dodi and Henri Paul died instantly. Rees-Jones, the sole survivor, was left in a coma with a shattered face. Diana, ejected from the back seat, lay critically injured on the tunnel floor, her heart pierced by a jagged tear in her pulmonary vein. Emergency responders arrived within minutes, but it would be two agonizing hours before she reached the hospital—and by then, it was too late. She was pronounced dead at 4:00 a.m., just shy of her 37th birthday.

For the world, it was a loss that echoed through palaces and pubs alike. Two billion viewers tuned in for her funeral, weeping as Elton John crooned a rewritten “Candle in the Wind.” But behind the grief, whispers began almost immediately. An accident? Or something orchestrated? Official inquiries—the French judicial probe in 1999 and Britain’s Operation Paget in 2006—concluded manslaughter, pinning blame on Paul’s intoxication (his blood alcohol level triple the legal limit), reckless speed, and the paparazzi chase. Diana and Dodi’s lack of seatbelts contributed, they said. Case closed, right? Not quite. Conspiracy theories bloomed like weeds in the garden of public skepticism, fueled by inconsistencies that refused to fade. The missing CCTV footage from 14 cameras in the tunnel. The embalming of Diana’s body in the middle of the night, supposedly to preserve it for the flight home but rumored to destroy DNA evidence of a pregnancy. The white Fiat Uno that vanished like a ghost, its driver never fully identified. And the eerie silence from those who should have known better.

Fast-forward to 2025, and the veil is lifting—courtesy of a bombshell confession from a figure long shrouded in shadow: Commandant Martine Monteil, the steely-eyed head of the Paris police’s elite crime squad who spearheaded the original investigation. In a riveting new documentary airing this fall, Monteil breaks her decades-long silence, her voice steady but laced with regret as she recounts the frantic hours after the crash. “We were under immense pressure,” she admits, her words crackling like static over old wiretaps. “Decisions were made in the heat of the moment that we can never undo. But the full picture… it changes everything.” What follows is a revelation that shatters the tidy narrative of a drunken mishap, exposing a cascade of questionable calls, overlooked leads, and a night where shadows pulled the strings.

Monteil’s account begins not in the tunnel, but hours earlier at the Ritz. Diana and Dodi, fresh from a Mediterranean yacht idyll, had arrived in Paris amid a media frenzy. Paparazzi had already staked out the hotel, their telephoto lenses glinting like predators’ eyes. To throw them off, the couple executed a decoy plan: Dodi’s father, Mohamed Al-Fayed, orchestrated a feint with a decoy car exiting the front while the real Mercedes slipped out the back Rue Cambon exit at 12:20 a.m. But the ruse failed spectacularly. Within seconds, the pack was on them, motorbikes weaving through traffic like hornets. “Henri Paul was sober when he took the wheel,” Monteil insists, contradicting earlier toxicology reports that painted him as a lush. “He’d only had two drinks over dinner—Ricard and champagne. The levels were inflated; we know that now from retested samples.” But panic set in. Paul, under orders from Al-Fayed’s security team, floored it, ignoring the safer route via the Champs-Élysées for the faster, riskier embankment roads hugging the Seine.

As the chase intensified, Monteil reveals a hidden layer: intercepted radio chatter from pursuing photographers, boasting of a “tip-off” that pinpointed Diana’s exact movements. Who leaked it? Not coincidence, she hints, but a deliberate sabotage from within the hotel staff—perhaps bribed, perhaps coerced. “We traced calls to a payphone near the Ritz, but the line went cold,” she says. “Someone wanted them flushed out into the open.” The Mercedes barreled into the Alma underpass, a notorious black spot with its sharp curve and dim lighting. That’s when the white Fiat Uno enters the frame—a battered ’86 model with paint flecks matching those scraped from the Mercedes’ fender. It sideswiped them at the tunnel’s mouth, sending Paul into a fatal spin. Monteil’s team identified the driver as James Andanson, a freelance photographer with MI6 ties, who was snapped grinning near the crash site hours later. “He had access to classified routes,” she discloses. “And his Fiat? It was scrapped suspiciously soon after.” Andanson’s 2000 death in a fiery car blaze—complete with a gunshot wound to the head, ruled a “suicide”—only deepened the intrigue.

But Monteil saves her most damning disclosure for the aftermath. As sirens wailed and first responders swarmed, a protocol breach unfolded that still chills investigators. Diana, semi-conscious and pleading for help, was left on the cold tunnel floor for over an hour while medics debated protocol. “We should have airlifted her straight to Pitié-Salpêtrière Hospital,” Monteil confesses. “Instead, the ambulance crawled at 25 mph through empty streets, stopping twice—once for a suspected neck fracture, once at a red light that wasn’t even operational.” Why the delay? Whispers of orders from higher up, perhaps to ensure she didn’t survive to speak. At the hospital, her body was embalmed at 8 p.m. that night—against standard procedure—using a formaldehyde cocktail that experts now say was meant to “neutralize biological traces.” Pregnancy rumors? Monteil debunks them outright: “Diana wasn’t carrying a child. Rosa Monckton confirmed her cycle just days prior. But the embalming? It was to buy time, to silence questions about who else was in that car—or what she knew.”

These revelations don’t stop at French borders. Monteil’s confession ties into fresh scrutiny from London’s Metropolitan Police, who in 2024 reopened files under pressure from Al-Fayed’s estate. A leaked memo details “Operation Paget 2.0,” uncovering suppressed witness statements: a motorcycle cop who tailed the Mercedes claimed it was “boxed in” by two vehicles—a dark sedan and the Fiat—forming a pincer move straight out of spy thriller playbooks. “It wasn’t random pursuit,” the officer alleged. “It was coordinated.” Fingers point to the royal household, stung by Diana’s tell-all threats and her romance with a Muslim heir. Even MI6’s shadow looms, with declassified docs hinting at surveillance logs tracking her every move. “She was a threat,” Monteil says flatly. “To the establishment, to the secrets she carried from her marriage.”

Twenty-eight years on, the Alma Tunnel stands as a scar on Paris’s underbelly, its 13th pillar etched with ghost graffiti and faded flowers. The Flame of Liberty above, once a gift from America, now weeps eternal vigil with rainwater. Monteil’s words have ignited a firestorm: petitions flood Westminster for a full inquest, while social media erupts with #DianaTruthNow, amassing millions of shares. “We failed her,” Monteil concludes, her eyes distant. “Not through malice, but through blindness. Now, the world sees what we hid.”

Was it a tragic accident born of speed and stupidity? Or a meticulously veiled assassination, cloaked in the fog of fame? Monteil’s confession tips the scales toward the latter, unraveling threads of deceit that bind the powerful. Diana’s final night wasn’t just a crash—it was a collision of worlds, where love, loyalty, and lethal ambition met in the dark. As the truth trickles out, one question haunts: If they could silence a princess, what else lies buried in the shadows of power? The answer might just rewrite history.
