Eighteen months ago the Assad regime suddenly collapsed, and the first lady and her family fled to Moscow.

Chloe learns of allegations that Asma - the ‘mother of the nation’ - had an active role in one of the regime’s cruellest strategies: separating the children of dissidents and rebel fighters from their parents to use them as bargaining chips. At an orphanage in Damascus, Chloe gets closer to the truth.

Emma is a high achieving, middle class girl from west London. She seems destined for a successful career in banking and a comfortable British life. Until she makes a decision that will come to define her. In 2001 Emma marries Bashar al-Assad - the now infamous dictator of Syria.


In the early days, people inside and out of Syria dared to hope. Alongside his beautiful, progressive wife, Bashar promised to modernise the country.


But when the Arab Spring reached Syria in 2011, Bashar's regime showed itself for what it really was: a brutal force, willing to capture and kill ordinary Syrians demanding change. And in all the years that a war raged on, Asma stood by her husband. She seemingly ignored the desperate pleas to stop her husband from killing his own people. 


But what did she really know about the atrocities her husband’s government was carrying out? And what choices did she really have? Some people allege that she actually assisted the regime and cashed in on the war, that she herself is a war criminal. Others say she tried to run away but was trapped, held hostage by a regime who threatened her life and her children. 


So, who is the real Emma?

On 6th October 1987, a newborn baby is found on the verge of a remote country lane in Suffolk. Police comb the area for clues and appeal for witnesses, but the mother is never found. The baby, Jess, is adopted. Journalist Lucy Greenwell has never forgotten the day when Jess was discovered. She was a child and lived nearby. For decades Lucy has wondered; what happened to Jess, and what could have driven a mother to leave her child in such an isolated place? When Lucy tracks Jess down, she finds a woman already deep in her own search for the truth, and a story far more tangled than either of them expected. What unfolds is a tale of long-held secrets and unintended consequences that spirals out of Jess’s control.

Raynor Winn’s memoir The Salt Path was a bestseller and literary phenomenon with millions of people captivated by this true story of financial ruin, terminal illness, and healing through nature. Raynor Winn has since published two more books and The Salt Path has been adapted for the big screen, starring Jason Isaacs and Gillian Anderson.


At its heart it is a simple tale, of a couple embarking on a 630 mile trek in the face of stark adversity. When faced with nothing, they chose to walk.


But when reporter Chloe Hadjimatheou received a tip-off that the memoir may not be the "unflinchingly honest" account it claimed to be, suddenly things began to unravel. And the questions, about what is and isn't true, began mounting.


How far can you bend the truth before it begins to break?

Three years ago travel writer Lydia Gard discovered freediving almost by accident. It’s an extreme and beautiful sport defined by one simple objective: to dive as deep as you can on one single breath. Record holders are now routinely diving to more than 120 metres, pushing the sport and their bodies to find out what’s humanly possible.


Through her coach, Lydia was drawn into a small but fanatical community of competition athletes all united in their drive for depth, and that’s where she stumbled on a darker side of the sport. Rumours swirled that a group of top divers were doping to get deeper, faster. 


As the community began to turn on each other over the allegations, one prominent diver decided to take the law into his own hands. A secret sting operation was meant to put an end to the problem by bringing the alleged dopers out of the dark, and into the light. But the issue hasn't gone away. And now, a lot of people who’ve been too scared to speak up, are ready to talk.

Introducing...The Lab Detective


Kathleen Folbigg experienced unimaginable loss. All four of her infant children died suddenly, over a 10-year period. Their deaths were unexplained. Until a police detective turned up at her door, and arrested Kathleen on suspicion of murder. 


She was labelled ‘Australia's worst female serial killer’, convicted, and was destined to spend most of the rest of her life in jail. 


Until a different type of detective entered her life. A scientist working in a lab who uncovered the truth behind the deaths. 


This is the story of a shocking miscarriage of justice, but as journalist Rachel Sylvester starts to investigate how this happened, she learns that Kathleen is not alone – other mothers have endured the same fate, and may also be in prison. 


The Lab Detective is a story about the power of science, and the determination of those searching for the truth.
