File on 4

Dodgy diamonds, missing millions - and the victims failed by justice. It starts with a phone call. Cynthia Tuck, a retired nurse and widow in her 80's, is charmed by a man offering her the chance to help put her grandchildren through university. All it would take is a small initial investment. Fast forward three years and Mrs Tuck has lost her entire life savings - hundreds of thousands of pounds. Three years on, in 2019, her fight for justice has hit a dead end. No charges. No trial. Everyone involved still at large. What went wrong? And why is the system failing millions of fraud victims like Cynthia Tuck? Reporter: Dan Whitworth Producer: Simon Maybin Editor: Hugh Levinson

To its thousands of employees left unemployed or 150,000 holiday makers stranded overseas, the collapse of Britain’s oldest travel firm came as a bitter, unexpected shock. File on 4 takes a forensic look at the demise of the 178-year-old company, revealing how it came about, the warning signs that were ignored and why a last, desperate attempt at a bail-out came too late. Speaking to Thomas Cook insiders, the programme uncovers how senior executives made millions while loading the company with debt, and were unable or unwilling to change course. It also follows the progress of some of those pilots, cabin crew and shop staff who lost their jobs as they pick up the pieces and try to find their way back into the workplace.

New figures have revealed at least four thousand young people are currently caught up in county lines – meeting orders for heroin and cocaine placed on mobile phone ‘deal lines’. They’re transporting drugs from cities to rural and coastal towns, and carrying weapons too – knives, hammers and acid. Many find themselves selling drugs in a strange town. Trapped, too scared to leave. Increasingly, when police raid the ‘traphouses’ where the drugs are held, they’re finding girls. But how many young women are caught in the county lines? Some are being recruited online for their ‘clean skins’ - a lack of a criminal or gang connection – so they’re less likely to be known to police and stopped. Others are used to launder money or facilitate travel and accommodation. The focus on boys working for the lines means girls have often been overlooked. Police chiefs guess 10 to 15% of children involved are girls. But they admit they have no real idea of the number of girls trapped in this violent world. File on 4 hears the female view from the county line, told by girls and women who’ve lived the life and witnessed serious violence. They reveal the particular reasons gangs want girls involved, as county lines become more sophisticated. Girls are less likely to be stopped, or undergo intimate searches by police. They are trapped through sexual violence and threats to kill. But with few projects offering specialist support to female members of county lines, are girls more at risk of being dragged back into the gangs?

The decision to scrap the Sex Offender Treatment Programme raised major concerns about the rehabilitation of prisoners and the impact on victims. The scheme was replaced five years after initial research suggested it wasn’t working - and might even increase the risk of re-offending. There are now calls to ensure that other courses, including those which cater for violent offenders, are properly evaluated. Campaigners claim the system for assessing the effectiveness of such programmes is too secretive and needs to be made more open. Some experts believe there’s been an over-reliance on treatment schemes as a way of calculating the risks posed by prisoners. Victims say some prisoners are playing the system – accessing programmes to convince the authorities they’re safe to be released. Former inmates say education and training are more likely to stop offenders returning to a life of crime, while there’s emerging evidence that providing newly-released prisoners with support in the community is the key.

Julie Montacute-Carter (pictured left) was found drowned in a lake after suffering from depression for many years. But when it came to the inquest into her death it fell to her daughter Becky Montacute to represent the family at the start of the inquest process - and then find and fund a lawyer herself. All because the family could not get Legal Aid. The mental health trust responsible for Julie's care however was able to spend tens of thousands of pounds in legal representation. Critics call this an 'inequality of arms' and there are concerns vital lessons aren't being learned because many families can't afford to pay for legal representation to challenge state bodies like the NHS, the police and the prison service.
