The lead French investigator into Princess Diana‘s death found ‘little clues’ at the scene of the tragic car crash in Paris, including ‘tiny pearls’ belonging to the royal.

Brigade Criminelle chief Martine Monteil, who was first to arrive on the scene, recalled how they found broken car bits, evidence of braking and traces of paint on the vehicle carrying Diana and her lover, Dodi Fayed. Driver Henri Paul also died.

Monteil said she was ‘obsessed’ with finding even the tiniest evidence, like the pearls, because it was all ‘important’ when probing what happened in the Pont de l’Alma tunnel on August 31, 1997.

The officer’s testimony is featured in episode one of Investigating Diana: Death In Paris, a documentary beginning tonight on Channel 4 to mark the 25th anniversary of the tragedy.

The four-part series examines two police investigations into the royal’s death, as well as the conspiracy theories alleging her death was staged by other British monarchs.

The first instalment of the upcoming docuseries follows the immediate aftermath of the crash and investigation led by France’s elite Brigade Criminelle.

‘We started to find these little clues,’ Monteil said of the initial crash scene, in an exclusive clip of the interview provided to Mail Online.

‘We saw signs of braking. Pieces of red light from another car. On the side of the car were traces of paint.

‘I was obsessed with finding things because it’s important.’

Monteil added: ‘I even found some tiny pearls. They belonged to the Princess.’

French detectives reportedly dove straight into the investigation, reconstructing the car’s route and chasing every possible lead. They also were forced to manoeuvre between ‘unreliable witnesses and fallible memories.’

Brigade Criminelle officer Eric Gigou shared how police took the paparazzi into custody and used their photos to piece together the moments before and after the crash.

‘We reconstructed the route they took,’ he explained. ‘Tried to discover all the witnesses, people who might have crossed paths with the car, seen motorcycles, seen something.

‘For us it’s a race against time that started the moment we were given the case because human memory is volatile and over time memories fade.

‘The paparazzi are in custody. From their photos, we could see the last minutes before the accident. We could identify the people around the vehicle in the seconds afterwards.’

Investigators note how they also had to block out ‘countless conspiracy theories’ that sprung up – both in the press and online – almost immediately after the crash.

The documentary covers the dual investigation into Diana and Dodi’s deaths, the initial 1997 inquiry by the French Brigade Criminelle and Operation Paget, as well as the inquest into the pair’s deaths. It features interviews with both the French and Metropolitan police forces.

It also probes the Scotland Yard chiefs’ handling of a note detailing Diana’s fears she would be killed in a staged car accident.

Diana voiced her fears to her lawyer, Lord Mishcon, in October 1995. After Diana’s death, he passed his contemporaneous typed account of their meeting to senior Metropolitan Police officers who put it in a safe. But the note was not passed to French authorities investigating her crash for six years.

There have even been suggestions of a mysterious addition to the note, which it has been claimed was designed to give cover to the fact the original note was not released earlier.

The Mishcon Note, as it became known, may well feature in Prince Harry’s upcoming controversial memoir, due later this year ahead of the Thanksgiving and Christmas holidays.

Harry is said to be ‘intensely focused’ on investigating his mother’s final hours. He and his brother, Prince William, had only ‘limited knowledge’ of the 1997 accident and neither were made aware of key details for almost a decade.

Why didn’t Scotland Yard share the note on Princess Diana’s fear that she would die in a staged car crash? Documentary says it wasn’t passed to Paris investigators until SIX YEARS after tragedy 

By Sue Reid for the Mail on Sunday 

Scotland Yard chiefs face new concerns over their handling of a note detailing Princess Diana‘s fears she would be killed in a staged car accident.

Diana voiced her fears to her lawyer, Lord Mishcon, in October 1995. She died in a car crash in Paris two years later alongside Dodi Fayed and driver Henri Paul.

The mystery surrounding the note is revisited in a four-part documentary – Investigating Diana: Death In Paris – beginning tonight on Channel 4 to mark the 25th anniversary of the tragedy.

After Diana’s death, Lord Mishcon passed his contemporaneous typed account of their meeting to senior Metropolitan Police officers who put it in a safe. But the note was not passed to French authorities investigating her crash for six years.

Diana’s brother and sisters learned of its existence only more than a decade after it was written. Princes William and Harry were also left in the dark for a long time.

There have even been suggestions of a mysterious addition to the note, which it has been claimed was designed to give cover to the fact the original note was not released earlier.

Operation Paget concluded that Diana’s death was a ‘tragic accident’. There was, Lord Stevens concluded, ‘no evidence’ of a murder conspiracy or a cover-up by MI6 (Pictured: Wreckage of the car Diana died in after it crashed in the Alma Underpass, in Paris, being lifted onto a truck)

According to John Morgan, author of How They Murdered Princess Diana, a second page was written in pen on a different pad and on different dates.

At his meeting with police chiefs the month after Diana’s death, Lord Mishcon read his note aloud to stress its importance. He told officers that it recorded Diana saying that ‘efforts would be made if not to get rid of her by some accident in her car, such as a pre-prepared brake failure… at least to see that she was so injured or damaged as to be declared unbalanced [in her mind]’.

Michael Mansfield, a lawyer who represented Fayed’s father Mohamed Al Fayed, tells tonight’s programme: ‘The note is important because it’s equivalent to somebody’s premonition. If you were a police officer investigating it, you want to hand the account over to the French. They didn’t do that. They stick it in the safe and they don’t reveal it.’

The Mishcon Note, as it became known, may well feature in Prince Harry’s controversial memoir, due out later this year.

Harry is said to be ‘intensely focused’ on investigating his mother’s final hours. Neither he nor his brother were aware of key details for almost a decade, according to the documentary.

In 2006, former Met commissioner Lord Stevens led Operation Paget, which investigated conspiracy theories surrounding the accident. Later that year, he briefed William, then 24, and Harry, 22, at Kensington Palace for 90 minutes about his report’s detailed findings.

Until then, the Princes had only ‘limited knowledge’ of the accident. Lord Stevens said he fielded ‘very pertinent questions’ from the Princes, saying later it was a ‘difficult session for them’.

‘I was in possession of the facts of what had taken place, from the beginning of the problem outside the Ritz with the car, to the death and bringing back the body,’ he said. ‘They wanted to know the circumstances of the death, what had happened to their mother, in every aspect. Some questions were in detail – which I answered, because they hadn’t been told of the circumstances.’

Operation Paget concluded that Diana’s death was a ‘tragic accident’. There was, Lord Stevens concluded, ‘no evidence’ of a murder conspiracy or a cover-up by MI6.

He blamed the drunken driver, Henri Paul, for the high-speed accident, which happened as Diana and Dodi drove from a dinner at the Ritz hotel to an apartment.

Lord Mishcon died aged 90 before the inquest but had given a statement to Operation Paget, which is how existence of the Mishcon Note emerged and how Diana’s sister Sarah first heard of it.

Sandra Davis, a lawyer working for Mishcon who was at the Diana meeting, told the inquest: ‘Lord Mishcon was concerned to take the note… because he thought that it was important that the police knew that he had made it and that she [Diana] had said what she had said.’

A record was made by police of their September 1997 meeting with Lord Mishcon. It concluded that ‘if it ever appeared’ there were some suspicious factors to the death crash, the lawyer or his firm would be contacted by Scotland Yard.

But when the same record appeared at the inquest years later, it had a second page attached with wording that backed up the police decision to keep the note secret.

The Mishcon Note came to light when Diana’s butler, Paul Burrell, revealed that he possessed a similar letter from Diana predicting her death. Lord Mishcon tried to contact Lord Stevens and police consulted lawyers about what to do with the Mishcon Note in the safe.

It eventually arrived on the coroner’s desk from Scotland Yard on December 30, 2003. An inquest into Diana’s death was opened a week later, then adjourned. It concluded in 2008 that she was ‘unlawfully killed’, partly because of the ‘gross negligence’ of the driver.

Princes William and Harry didn’t learn key details of how their mother died for almost a decade, according to a new Channel 4 documentary 

By Claudia Joseph for the Mail on Sunday

Princes William and Harry didn’t learn key details of how their mother died for almost a decade, according to a new Channel 4 documentary on the conspiracy theories surrounding the tragedy.

Former Scotland Yard chief Lord Stevens, whose investigation into her death forms the basis of the programme, revealed that the two princes had only ‘limited knowledge’ of the 1997 accident in Paris.

Nine years later, in December 2006, Lord Stevens was invited to Kensington Palace to brief the William and Harry about his report’s detailed findings ahead of publication.

It was, he said, a ‘difficult session for them’, which lasted some 90 minutes. He fielded ‘very pertinent questions’ from the Duke of Cambridge, then 24, and Duke of Sussex, 22.

‘I was in possession of the facts of what had taken place, from the beginning of the problem outside the Ritz with the car, to the death and bringing back the body,’ Lord Stevens told The Mail on Sunday.

‘I went in and had an hour, an hour and a half, with them, giving them the details of what took place. Over half the time, I was answering their questions.

‘I sat opposite them and they sat together on the couch. I know they believed me.

‘Generally, they wanted to know the circumstances of the death, what had happened to their mother, in every aspect.

‘Some of the questions were in detail – which I answered, because they hadn’t been told of the circumstances.

‘I think that was an important thing to do, for them – and I think they appreciated that. It was quite an emotional session.’

‘It was so intense, to be perfectly honest, I don’t think any of us wanted a coffee or any drink. They had very pertinent questions about what happened to their mother and I was there to answer those questions.’

Lord Stevens tells the documentary he’d been in touch with Prince William as part of his initial fact-finding stage of his inquiry,.

‘We exchanged correspondence to inquire about what William knew about his mother and her habits beforehand,’ he said, ‘and whether she said anything about getting married to Dodi, which he didn’t know about at all.’

Prince Harry sees his mother’s ‘legacy’ in his children every day

Lord Stevens also reveals that neither of the princes believed any of the allegations made by Mohammed Al Fayed, father of Dodi, who also died in the crash, on August 31, 1997.

During the years after the accident, the former Harrods owner had offered a litany of wild theories and barely credible accusations, not least that the princess had been pregnant at the time of her death and that key members of the royal family were somehow involved in an extravagant murder plot.

The subsequent report found that all conspiracy theories – some 104 in total – were entirely without foundation.

Prior to the report’s publication, Lord Stevens had tried to brief Al Fayed on its contents. But, despite having had weekly meetings during the three-year investigation, the Egyptian-born businessman turned him away.

‘I went down to Harrods, and he refused to see me,’ he said. ‘We gave him the results of the report through his legal team, and he refused to see me.’

In the documentary, Lord Stevens also details how he interviewed Prince Charles at St James’s Palace about a note written by Diana – and left in the pantry of Kensington Palace for her butler, Paul Burrell, to find.

In it, she predicted that she would die through ‘brake failure and serious head injury’.

It was later suggested that disgraced BBC journalist Martin Bashir – who used bogus papers to con the princess into granting him an interview for Panorama, in 1995 – had exacerbated her sense of paranoia at the time the note was written.

Prince William: Diana inspired me to shine a light on homelessness

‘The allegation had to be investigated,’ Lord Stevens tells the documentary, ‘whether it’s the future King of England or anyone else. You have to go there. No one is above the law.

‘I wasn’t frightened of the Establishment; the decision was made to see Prince Charles because of the Burrell letter and the allegations made in that letter.

‘Princess Diana had stated that she was going to be murdered by her husband. We had to see if there was any substance to that, and we had to have his reply to it.

‘I’m sure nothing like that had ever happened before, so that was unprecedented. He didn’t mind being involved in any way shape or form and that was noted.’

Lord Stevens was among dozens of police officers, medical professionals, firemen and eye witnesses interviewed for the four-part series, Investigating Diana: Death in Paris, which begins on Channel 4 tonight.

It covers the dual investigation into Diana and Dodi’s deaths, the initial 1997 inquiry by the French Brigade Criminelle and Operation Paget, as well as the inquest into the pair’s deaths, and features interviews with both police forces.

Alan Brown, who was Metropolitan Police Assistant Commissioner at the time of the report, told the programme: ‘Ultimately, you had two young boys grieving. They were probably more affected than anybody else.

‘To have somebody suggest that their father and their grandfather had some responsibility for their mother’s death, you know, no matter how small that kind of concern was – and the fact that it was constantly being repeated in the press – to be able to give them confidence as to what happened and why it happened in itself was really important.’
