As the trial draws towards a conclusion, the jury are introduced to a science lesson. Can microscopic algae, found in the River Leven, help answer the question of whether any of the accused entered the water? The jury also hears from some police officers involved in the original enquiry, finding out why the accused weren't brought before a court at the time. And as the final witness completes their testimony, the jury are sent away, ahead of the closing speeches, and the opportunity to reach a verdict.

After seven days of evidence for the prosecution, it's time for the defence to lead the evidence. And they start with testimony from one of the three accused. Can their account convince the jury of their innocence? Or will the cross-examination prove to be damning? Also taking the stand are two witnesses who support the idea that George Graham may be culpable. What value will the jury put on these claims?

What did the three accused say when they were quizzed by detectives? As the prosecution case comes to a close, we hear extracts form those interviews. We learn how all three insist they had nothing to do with Caroline's death. And hear the observations of the officers tasked with obtaining their account. Then - in a dramatic twist - the prosecution announce that one of the charges in the case is set to be dropped. What does this mean for the rest of the trial?

Did the accused really take a walk with Archie in the middle of the night? And did they really come back to the house, and start arguing? Well - this episode hears evidence form a witness who says she SAW them through her window. The only problem - they never mentioned seeing anything at the time. We also hear evidence from another witness who spent time talking to young Archie Wilson. And - we hear a claim that Caroline was in fear of George Graham - another man once accused of her murder.

Witnesses can come in all shapes and sizes. But in a murder trial it's rare to hear evidence from the voice of a five-year-old. In this episode, we break down the events from a dramatic day-5 in court, as the jury is told that a five year old boy may have witnesses the murder, and revealed who was responsible. But is he telling the truth? The court also hears from witnesses who may have seen, or heard, the suspects leaving an address and heading towards the scene of the murder. But will their evidence prove to be consistent, or pose more questions than it answers? Tommy Ross KC and journalist Jane MacSorley listen to the evidence, and provide the context behind the questions.

The police know that Caroline Glachan made her way to the River Leven on the night she was killed. So todays evidence, in which two people claim to have been with her on that walk, could complete the picture and reveal what exactly happened. But when the witnesses offer very different versions of events, will that throw doubt into the mind of the jury? Tommy Ross KC breaks down the events as he and journalist Jane MacSorley listen to the evidence and guide listeners through every twist and turn.

Day two of the trial centres on evidence from Caroline's best friend, who reveals concerns about one of the three accused. There's also evidence from a witness - potentially someone who heard the attack on Caroline being carried out. And the 999 call, made by the person who found Caroline's body in the River Leven, is played to the court. There are questions about why Caroline's shoes are placed neatly on the riverbank. And theories about whether this might point to the motive behind her murder. But the day begins with evidence from a pathologist, who can explain the range of injuries Caroline sustained, and what they might reveal about the person responsible. Tommy Ross KC, joins journalist Jane MacSorley to discuss the events in court and provide an insight into the trial process.
