The naked body of a young woman is found in isolated woods. Police never catch her killer. Journalist Sam Poling's investigation takes her into a dark and unsettling world of sex, rape, lies and murder. And it leads her to confront the man she believes is a prime suspect.

From BBC Scotland, Who Killed Emma? Is an eight-part podcast that forensically takes apart the police investigation into Emma's murder and unravels the impact of a series of coincidences and missed opportunities until a clear suspect starts to emerge.
