London couple found guilty of murdering French nanny Sophie Lionnet

A chilling image shows gaunt-looking nanny Sophie Lionnet just days before she was murdered by her employers, as the victim’s mother branded her killers ‘monsters’ who ‘starved, tortured and broke’ her daughter.

French au pair Miss Lionnet was waterboarded and beaten to death at the London home of Sabrina Kouider and her partner Ouissem Medouni after being put through brutal interrogations which were recorded by the paranoid pair.

The couple were convicted of murder today after an often-disturbing trial heard how they became convinced their nanny was spying on them for the mother’s former Boyzone member ex.

Speaking after the verdicts, Sophie’s mother Catherine Devallonne said: ‘These monsters repeatedly beat Sophie. They starved her, tortured her and broke her until she could no longer fight.

‘We have now been tortured ourselves, forced to listen to Sophie’s last moments, her sobs and her crying.’

Addressing Kouider directly, the furious mother said: ‘Sabrina. No amount of shaving will ever cleanse your soul. No one, no God will ever forgive you both for what you have done to our daughter.’

Her statement was a reference to Kouider having taken shower and shaved her body after the murder, saying she needed to ‘clean her sin’.

The judge assured the victim’s parents that there was no truth in the allegations the couple had made against their daughter and she was in no way to blame. 

Sophie’s mother, Ms Devallonne, said today: ‘My heart is broken, shattered into a million pieces. Sophie’s loss will not be meaningless, lessons will be learned.’ 

The shocking trial has heard how Kouider was obsessed with her former lover, Boyzone founding member Mark Walton, and convinced herself the nanny had been hired by him to spy on her.

Miss Lionnet was completely innocent and had never met Mr Walton, but that did not stop Kouider making increasingly outlandish claims against the quiet 21-year-old, which turned into violent beatings.

The au pair did not have the money for the flight home to France and so became trapped in the couple’s terrifying cycle of recriminations and violence before she died during a beating last September.

Having killed her in the bath, the pair threw her on a bonfire in the garden of their home, as they barbecued chicken nearby.

Kouider and Medouni blamed each other for the murder in a cut-throat defence but were convicted by an Old Bailey jury after a week of deliberations. 

Kouider, who had ranted at her former lover throughout the trial, cried and shook her head in the dock before the verdicts were returned. 

The self-proclaimed ‘fashion designer’ was found guilty unanimously and burst into hysterics, saying ‘no’ and shaking her head.

Medouni was convicted on a majority of 10-2. He wept quietly and stared at the floor as the verdicts were read out.

Sophie’s mother Catherine Devallonne had cried quietly to herself as she waited for the jury to come back.

Following the conclusion of the trial, Judge Nicholas Hilliard QC, told Sophie’s parents: ‘I am absolutely sure that there was no truth whatsoever in the allegations that were made against your daughter.’

Kouider carried on shrieking and shaking her head as the judge consoled the family.

Miss Lionnet came to work for the couple after a friend of Kouider’s brother Djamal suggested she try out as their nanny.

In January 2016, a few days after her 20th birthday, she moved in permanently with the couple in Southfields, south London.

It was the first and only job she ever had and, even though she was paid just £50 a week, she was constantly criticised by Kouider for being ‘lazy’. 

Kouider was fixated with her ex-boyfriend Mr Walton and created a fantasy world casting Mr Walton as an evil villain who seduced Miss Lionnet with sex and promises of Hollywood stardom.

Banker Medouni became an ardent believer in Kouider’s twisted reality and they interrogated Miss Lionnet for hours to get to ‘the truth’.

The paranoia which led to Miss Lionnet's murder sprang from Kouider's obsession with her ex-boyfriend Mark Walton, who gave evidence at the trial

Jurors heard more than eight hours of recordings in which Miss Lionnet was slapped, likened to a Nazi collaborator and called ‘worse than a murderer’ by her tormentors. 

For over a month, Miss Lionnet was interrogated, beaten and threatened by the couple as she desperately tried to appease them with false confessions and apologies.

Sophie’s mother Catherine Devallonne begged Kouider over the phone to send her daughter home, but Kouider said she would not do so until she learned ‘the truth’ about Sophie and Mark Walton. 

In a filmed ‘confession’, the emaciated and broken young woman admitted she had drugged Medouni so Mr Walton could sexually assault him. Within hours, she was dead. 

In the 48 hours before she died, Sophie suffered fractures to her breast bone and five of her ribs that were inflicted with severe force.

Interrogation transcripts show killer’s paranoid anger

Excerpts of transcripts of the interrogation show what Miss Lionnet was put through.

Kouider was heard shouting: ‘I will not leave you alone until you tell methe truth. Is this clear? Do you understand?

‘You will not go back to France until you’ve told me the truth!

‘I am going to spoil your life, as you have spoiled mine!’ 

She later said: ‘Whenever you come back to the house, I smell sex.’

She also screamed: ‘I hate lies. I hate, I hate, I hate lies, so stop telling lies and tell me the truth.

‘Go on! I am with you. I am on your side. Go on! Go on Sophie. Go on! Quickly!’

In a filmed ‘confession’, the emaciated and broken young woman admitted she had drugged Medouni so Mr Walton could sexually assault him. Within hours, she was dead. 

The precise cause of  her death may never be known.Pathologists believe she may have been drowned or suffered a blow to the head.

According to Kouider, Medouni tortured her in the bath, then demanded they have sex as she lay dead nearby. 

She told jurors: ‘He was putting her head under the water and sometimes he would put water on the towel in her mouth. It was getting really mad.’ 

For two days after she died, the couple kept the body in a suitcase in their shed, uncertain what to do.

But the couple’s attempts to cremate her body on the garden bonfire using nail polish remover as an accelerant meant that her corpse was too severely burnt for a precise cause to be established.

They were also about to set fire to a carrier bag full of Sophie’s written apologies, confessions and pleas for help when the fire brigade arrived.

Before the trial, Medouni claimed Miss Lionnet died by accident after he punched her during an interrogation in the bath.

He offered to admit manslaughter but later retracted his confession, saying he made it to protect his wife, who has been diagnosed with a borderline personality disorder.

Prosecutor Richard Horwell QC told jurors that neither were prepared to admit the truth – that they killed her out of ‘revenge and punishment’.

He said their ‘unhealthy, myopic, all-consuming and groundless’ obsession with Mr Walton had deprived them of reason and turned their nanny into ‘something less than human’.

The judge is expected to sentence the pair at the Old Bailey on June 26.

Chip shop owner who helped victim saw killer’s sickening tirade 

A takeaway owner has described getting ‘goosebumps all over’ when he witnessed Sabrina Kouider launch into a foul-mouthed tirade at her nanny.

Michael Croner befriended Sophie Lionnet and regularly give her food and a fizzy drink when she visited his fish and chip shop.

Kouider and Ouissem Medouni wanted to rent space from him for a French pancake stall, but he was put off after finding out what the fashion designer was like.

In an interview with ITV News, he said Miss Lionnet cried when she told him that she had been beaten.

Mr Croner said: ‘I started to talk to her as that was the time she wasn’t with anyone, by herself.

‘A couple of times she looked very sad, there were tears in her eyes, so then I started to talk to her – but it was still very hard to get anything out from her.

‘One incident, she really started to cry here, she had tears falling down. Then I asked her ‘What’s going on?’ That was the time she said somebody had beat her, so then I knew something was there.’

Mr Croner said it was a ‘big shock’ to hear she had been hit, and he knew she wanted to leave but he felt he could not interfere.

Kouider shouted at Miss Lionnet in French over the suggestion that Mr Croner wanted to help her get another job.

He told the broadcaster: ‘She yelled at her and yelled at her, then she stopped, looked at me and said ‘She’s a f****** b****, she wants sympathy from everyone. She’s got a man here, a man there’. That is where I really saw the real Sabrina.’

Mr Croner was asked if he had ever thought in his wildest dreams what the couple were capable of.

He replied: ‘No. Being with them doing things, I couldn’t believe it until the last meeting when she came and had a go at me. That was when I knew who this Sabrina was.

‘It was shocking. I was working behind the counter and I had goosebumps all over.’

Femme fatale killer described by an ex as a ‘fickle lunatic’ who grew to be obsessed with Boyzone founding member after he dumped her 

Sabrina Kouider was the star of her own fantasy film noir – and she cast Sophie Lionnet as the enemy.

The glamorous mother-of-two was born in Algeria but grew up with her mother in Paris, where she met her first love in the unlikely form of Ouissem Medouni.

At the age of 18, she had a summer job on a sweet stall at a funfair where she caught the eye of fellow French Algerian Medouni, who was five years her senior.

His ardent pursuit paid off, setting them up for a 17-year on-off relationship which ended acrimoniously in the dock of the Old Bailey.

The trial has heard how Kouider came up with increasingly wild theories about Miss Lionnet

In common with her other liaisons with men, it was dysfunctional, turbulent and unconventional, and marred by Kouider’s bouts of irrational jealousy and violence.

Prosecutor Richard Horwell QC tried to unravel their strange bond, suggesting it was a marriage of convenience which suited Kouider only until someone better came along.

Medouni was said to be weak and easily led, a perfect foil for Kouider’s domineering personality.

The couple met at a funfair when Kouider was 18. French Algerian Medouni pursued her and they had a 17-year on-off relationship

The couple met at a funfair when Kouider was 18. French Algerian Medouni pursued her and they had a 17-year on-off relationship

They both appeared keen to keep their relationship ambiguous, with Kouider regularly relegating Medouni to a relative or friend in public, rather than her life partner with an Islamic marriage certificate to prove it.

At first, Medouni provided some stability and security amid Kouider’s emotional turmoil, which, it was claimed, led to more than one failed suicide attempt.

When Kouider went to London to work as a nanny, Medouni followed.

She had turned her hand to pyramid selling for a telecommunications company when Mark Walton, of Boyzone fame, came into the picture.

In 2011, they had a chance meeting in a bank in Notting Hill and he fell head over heels in love.

Once the ‘love goggles’ wore off, Mr Walton discovered a calculating and manipulative woman who could flip and go ‘crazy’ in a moment.

Kouider claimed to know many celebrities and influential people from the party scene, and had been introduced to Blue pop star Duncan James through Mr Walton.

When she split from the music mogul, she went back to Medouni, who would come and go from their flat at will.

She helped with his French pancake stall and, at the time of her arrest, was hoping to get a fashion business off the ground with a show in central London hosted by a major charity.

Despite her grand plans, Kouider kept afloat by claiming benefits and accepting significant financial support from Mr Walton long after they split up.

When the handouts dried up, she racked up £20,000 in unpaid rent on her two-bedroom garden flat in the upmarket area in south-west London.

At the heart of her problems lay depression and a borderline personality disorder, creating a distorted view of the world, her trial heard.

Another ex-boyfriend, Anthony Francois, described her as ‘fickle’ and a ‘lunatic’ who would lie, manipulate and target the weak.

He said she could lash out at complete strangers, grabbing women’s hair just for looking at her.

Her character flaws fuelled an irrational obsession with Mr Walton entirely based on an alternative truth created in her mind.

She was so convinced that her ex-boyfriend was colluding with her nanny that she swept Medouni up into the fantasy too.

Frustrated and thwarted in her attempts to get to LA-based Mr Walton, she latched on to her naive young nanny as a soft target.

She was the driving force of the violent interrogations of Miss Lionnet, but claimed Medouni was responsible for her death in September last year.

‘No amount of shaving will cleanse your soul’: Nanny’s mother slams killer who washed after murder

The devastated parents of murdered nanny Sophie Lionnet slammed her killers in statement read out after the verdicts.

Sophie’s mother Catherine Devallonne said: ‘These monsters repeatedly beat Sophie.

‘They starved her, tortured her and broke her until she could no longer fight.

‘We have now been tortured ourselves, forced to listen to Sophie’s last moments, her sobs and her crying.

‘Sabrina, no amount of shaving will ever cleanse your soul.’

It was a reference to Kouider having taken a shower and shaved herself after the murder, saying she needed to ‘clean her sin’.

Ms Devallonne added: ‘No one, no God will ever forgive you both for what you have done to our daughter.

‘You will not be forgiven for the lies.

‘My heart is broken, shattered into a million pieces. Sophie’s loss will not be meaningless, lessons will be learned.’

The family’s interpreter Ian Macdonald read the statement in French before it was read out in English.

Father Patrick Lionnet described the ‘brutal shock’ of finding out about his daughter’s death.

‘The laughs, the hugs, the family celebrations, these special moments, they have all been tragically and brutally cut short by the people that had responsibility for Sophie’s care and wellbeing whilst she was employed by them,’ he said.

He described his daughter as ‘kind, quiet and reserved’ and said he had encouraged her to go to London and fulfil her ‘life goal’.

He said: ‘If only I had known what would happen to her at the hands of Sabrina and Ouissem, that she would undergo so much physical and mental torture, that her so young life was so selfishly and unnecessarily taken from her, I would never have encouraged her to leave. I would still have my little girl.

‘Sophie was so nurturing, she liked children and animals. She couldn’t stand seeing others suffering and it breaks my heart to know that she was abused to the end of her life.

‘It was Sophie who suffered in silence, beaten and receiving wounds incompatible with life. She was imprisoned. You don’t have to be physically chained up to feel you are a prisoner. Isolation and fear are just as effective.

‘Sabrina and Ouissem have not only stolen the life of my only daughter, so brutally and without remorse, they have also stolen mine. My sleep, my happiness, my peace of mind and my future.’

Nanny’s horrific murder has chilling echos of other ‘folie a deux’ killings

The murder of Sophie Lionnet bears all the hallmarks of a psychosis known as folie a deux.

Folie a deux, or ‘madness of two’, is defined as a delusion shared from one individual to another.

Depressive and borderline personality Sabrina Kouider was the driving force and weak Ouissem Medouni the willing party.

Even as the true facts were laid bare in court, the pair refused to accept what they had done was the product of their warped fantasy.

Judge Nicholas Hilliard QC said that even though there was evidence about their mental state, in particular Kouider, who was held at a medium secure mental hospital, none of it was a defence for murder.

Other high-profile and extreme examples of folie a deux include serial killers Fred and Rosemary West.

The case of New Zealand teenagers Pauline Parker and Juliet Hulme was made into the film Heavenly Creatures, starring Kate Winslett.

Chowdhury and Muddar convinced themselves little Ayesha was 'evil'

Perhaps the most strikingly similar case to be heard at the Old Bailey involved lesbian child killers Polly Chowdhury and Kiki Muddar in 2015.

The pair were convicted of the manslaughter of Chowdhury’s eight-year-old daughter, Ayesha Ali, who died at their home in Chadwell Heath, east London, in August 2013.

Muddar, who like Kouider has a borderline personality disorder, convinced Chowdury her daughter was evil and together they punished and terrorised her with scary masks before she died in the bath.

Unlike Kouider and Medouni, Chowdhury accepted in the trial that she had been swept up Muddar’s fantasy world of alter-egos.

‘I don’t want a charred body to be my last memory of Sophie’: Heartbroken father of murdered French nanny says he’s haunted by her death – and releases her touching childhood photos

Speaking from his home in France earlier this month, Mr Lionnet said: 'When I was in London [for the trial] I barely slept, maybe one or two hours a night. I have these terrible images in my head.'

Speaking from his home in France earlier this month, Mr Lionnet said: ‘When I was in London [for the trial] I barely slept, maybe one or two hours a night. I have these terrible images in my head.’

By Nick Fagge in Troyes for MailOnline 

The father of French nanny Sophie Lionnet says he is haunted by the death of his ‘irreplaceable’ daughter as her killers were today found guilty of her murder.

Fighting back his tears, Patrick Lionnet said: ‘I try to think of Sophie the last time I saw her – happy and smiling, but sometimes I cannot block out the horror.’

Looking through precious childhood photos of Sophie growing up, he said: ‘The picture of Sophie smiling in my house with the dog, telling me that she loves me and that she will miss me, has been replaced with the sound of my baby’s voice full of fear and thick with tears.

‘I have seen photos of her starved body – like something out of Auschwitz – that hardly resembled my precious child.

‘I don’t want the image of a charred body, a recognizable human nose and fingers to be my last memory of her.’

The guilty verdict brings no comfort to Mr Lionnet, 56, who says he struggles to block out the sound of Sophie pleading for her life – which was played to the court – when he closes his eyes.

He tries not to think of her charred remains of her body burned in the back garden of the family home in London where she worked as an au pair.

Speaking exclusively to MailOnline Mr Lionnet, a gardener for the local authority, from Troyes, south of Paris, tells how he ‘went through hell’ during the Old Bailey murder trial.

‘I try not to think about what they did to Sophie but I have been through hell.

‘When I was in London [for the trial] I barely slept, maybe one or two hours a night. I have these terrible images in my head.

‘When I heard the audio of Sophie being tortured I cracked. I just couldn’t take it. I cannot forget the images of Sophie’s body that were shown in court.

‘They are not human, they are savages. They don’t deserve to ever get out of jail for what they did to Sophie. I don’t ever want to see them walking free on the streets. They deserve the severest punishment possible.’

Sitting in the garden of his modest home in France, Mr Lionnet proudly wears the ‘I love Dad’ t-shirt that Sophie gave him as a Father’s Day present a couple of years ago.

Around his neck he wears a pendant bearing Sophie’s face. Portraits of her are displayed all around his unfussy rural home. The birthday card Sophie sent him from London has pride of place on his mantelpiece.

He went on: ‘Sophie was my old child, my pride and joy. She was the spitting image of me when she was born and she will always be my baby, no matter how old she is. I don’t have much money but I spoiled her.

‘We are also very similar in character – a bit shy and reserved, but happy. She was always smiling.

Sophie spent 14 months working as a nanny in London for £55 a week before she was murdered by the mother of the young boy she was looking after in September 2017

‘I remember her smiling and laughing the last time I saw her just before she went to England. I thought going abroad would do her good, open up new horizons for her, so I encouraged her to go.

‘She always liked working with children so I thought she would be happy. I never had any idea she was in trouble.

‘It breaks my heart to know that in her final months she was abused, that she suffered in silence and that beaten so badly.’ 

Mr Lionnet told how evil Kouider and Medouni had not only robbed him of his only child but of his future – walking his daughter down the aisle and the joy of becoming a grandfather.

‘They have not only stolen the life of my only child, so brutally and without remorse, they have also stolen my sleep, my happiness, my piece of mind, my future.

‘I will never have that moment of pride of seeing my baby girl dressed in white, with flowers in her hair and love and hope glistening in her eyes, as she takes my arm, to walk down the aisle to a man who would cherish her as much as I.

‘I will never hear my daughter say, ‘Daddy, you are going to be a grandfather’. I will never be called Granddad.’

He added: ‘What they did to my child is beyond comprehension and unforgivable.

‘The suffering they caused my young and impressionable daughter, our families and friends, is more than anyone should be forced to live with.

‘They have ruined everything that we held dear. They have murdered my daughter, who was dependent on them.

‘They burned her body so badly that she was unrecognizable. We have still not been able to lay Sophie to rest. We have not been granted closure. This nightmare doesn’t end for us.

‘We will carry the brutality of my daughter’s final moments in our hearts and souls for the rest of our lives.’

While Mr Lionnet separated from Sophie’s mother Catherine Devallonne when his daughter was four years old, he maintained a strong relationship with his little girl.

‘Sophie and I have always been close,’ he said. ‘She had more freedom when she was with me than with her mum.

‘She liked coming over. We would watch films and play video games together. She was friends with some of the other kids in the area.

‘If we didn’t see each other every week it was because of my work or because she wanted to do something. It was not a big deal. We were there for each other. She loved children and playing with animals.

‘She studied childcare at school. But she had trouble finding a job. So, when this opportunity came up in London we thought it was a good thing. 

‘Sophie came to see me before she went to London. She was happy.’

The young Frenchwoman set off for London in July 2016. Despite a meagre salary of just £50 per week, Sophie told her family she was looking forward to her foreign adventure.

Unable to top up her French pay-as-you-go mobile phone in the UK, the young nanny could not keep in regular contact with her family.

But 14 months after she left home she would be dead.

Mr Lionnet explained: ‘Sophie had a new phone and she couldn’t make international calls.

‘So, we talked to each other via Facebook. She also wrote to me. She sent me a lovely Father’s Day card.’

However, Mr Lionnet told how he received a knock at his door in the early hours of the morning in September last year to tell him his daughter was dead.

He told MailOnline: ‘It was four o’clock in the morning when the police knocked on my door. It was still dark. They would not give me any details about what had happened to Sophie, only that she was the victim of a violent murder. They told me to contact the [French] Ambassador in London.

‘I couldn’t believe it. I was in shock. I went to the boulangerie like I always do to collect the bread and then I went to work. 

Chilling audio tapes reveal terrified nanny’s ordeal as she was interrogated for days by murderous couple 

A French couple today convicted of torturing and murdering their nanny recorded horrific interrogations of their victim before they killed her.

Sabrina Kouider, 35, and Ouissem Medouni, 40, built a warped fantasy around music mogul Mark Walton and accused Sophie Lionnet of being in league with him.

Koudier recorded the brutal questioning sessions the couple held at their south-London home, as they quizzed the 21-year-old for information about Walton.

Police transcripts show how Miss Lionnet, who had never met Mr Walton, gave confused answers to the repeated questions as the couple became more enraged.

Below is excepts from an audio file recovered from Koudier’s phone:

The interrogations took place at the couple home in south London before Sophie's death

The interrogations took place at the couple home in south London before Sophie’s death

Medouni: Okay… Wait! We’re going to start again. So, everything you told Sabrina, why did you tell her all that?

Kouider: She was crying earlier on! She was crying and said to me, “I did something… and I can’t get myself to tell it to you. I am ashamed of myself. [Addressing Sophie] You did take him there! I have evidence, as well. Okay?

Medouni: Yes or no?

Lionnet: No, I don’t remember.

Medouni: What?

Lionnet (sounding scared or in tears): I have no recollection of going to someone else’s place with [child]?

(Loud crackling noise)

Kouider: You’re making fun of me, are you?

Medouni: Stop it!

Kouider: You’re making fun of me? You’re making fun of me?

Medouni: Stop it! Okay.

(A loud band with something metallic)

Kouider: Okay? …don’t make fun of me! No sweet talk! (Addressing Medouni) Because I told you she’s a monster. You have a monster there! I thought you were someone good!”

Medouni: Sit properly. You needn’t be scared. Okay?

Kouider: Exactly! Okay? Because, earlier on, you were crying and you said to me, “I did something very serious, and I am very ashamed of myself”. That’s what you told me. Yes, or no?

Medouni: And what’s that?

Kouider: Is it lie?

Medouni: What’s that?

Kouider: Is it a lie?

Lionnet (sounding scared and maybe in tears): I was scared!

Kouider: You were scared? You were scared? You lie as you breathe, because.. why did I scare you? Did I scare you?”

Lionnet: I was scared.

Kouider: What were you scared of? Scared of what? Scared of what? Because I was very, very, very nice to you! I was very, very, very, very, very nice to you!

Medouni: Stop shouting like this!… Go on! Scared of what?

Kouider: Scared of what? I had been too nice to her. I used to even tell her things….

Medouni: She said she was scared of you! Stop it, please! We…

Kouider: What were scared of? Okay. Sorry! Apologies!

Medouni: Scared of what?

Lionnet: I don’t know exactly.

Kouider: Scared of what? In any case, whether you speak or you don’t speak, at your trial, you will do so. You will be jailed. Because as far as I am concerned, I am not going to joke with you! Okay? Because, I am a nice person; okay? I’d really like to help you. You too must help me! Okay? If you want me to help you, you need to help me! Okay? You want us to help you? Then help us! Okay?

Kouider: I don’t think he abused you; you wanted it because he couldn’t do that with you. And whenever you come back to the house, I smell sex.

Medouni: …she smells sex.

Kouider: I smell it. I smell it. Where the house? Hurry up, where is the house? Hurry up hurry up, otherwise I will f****** make the call. Hurry up where is the house? Open your mouth where is the house?

Kouider: Open your f****** mouth. Where is the house? You don’t to say it. You don’t want to it. So you want to go to prison? Be ready it is either 40 years in prison or you leave. It is up to you. You have the choice. Think carefully about 40 years in prison. Close your eyes for one-minute ok and imagine yourself every day in a cage like an animal with other people inside. That’s not a laughing matter. With paedophiles and all the…

(Continuous bagging noise in the background)

Kouider: If you promise to tell me the truth and I later find out that it’s lie, I will not protect you. No more lies, I will not protect you, I swear on my life, Sophie. I will not allow any more lie.

Medouni: So, he asked you when you will be coming back. That’s the way he approached you. He doesn’t know you but sent a message through Facebook asking you when will you be coming back? It doesn’t make any sense.

Kouider: So he knew you.

Lionnet: No.

Kouider: Yes, he knew you because he asked you when you will be coming back. He knew you. Please just say the truth and nothing apart the truth.

Medouni: You better know that we will not let you go back until we know the whole, whole, whole, whole truth and nothing but the truth. It’s up to you.

Kouider: Tell me, huh! Tell me. Do you know this girl? Do you know this girl, I am just asking? Do you know her? …(Inaudible) He was with you, even the best of the best, they are going to be checked, ok. Do you know this girl? Because, there is everywhere CCTV. Do you know this girl?

Lionnet: No.

Kouider: 100%.

Lionnet: Huh, huh! Huh!

Kouider: Huh! Why do you take time in answering, huh? Why do you take time in answering? Why do you take time in answering, tell me, huh! Huh! Why do you take time in answering?

Lionnet: Huh!

Kouider: You don’t know. Sophie, please compose yourself, get your strength back. You just ate. I just fed you, please, put yourself together and get your strength back and answer me. I forgave you

Kouider: I am with you Sophie despite everything, despite everything, after everything, everything, everything, everything, everything, and everything. I am not against you. Go on Sophie. Why do, why do you take time to answer my question?

Kouider: Okay, how many of… did he give you for me? How many did he give you? Yeah? How many lozenges did he give you to put in the glass with tap water?… (Inaudible) free? You want to free yourself? Yeah? You want to free yourself? So do free yourself! Go ahead! Go ahead Sophie! How many did he give you? Where did you put them? In tea? In water?

Lionnet: Yes….

Kouider: Okay. How many?

Lionnet: (Faint, hardly audible voice)

Kouider: Okay, but how many did he give you?

Medouni: Each time he came, you put one in?

Kouider: Before coming…

Medouni: Well, before.
