We travel to Ayrshire to investigate the murder of 39-year-old Emma Faulds. Emma is reported missing when she fails to turn up to work, and on entering her home, police find her beloved pet dog alone.

Police interview the last person to see her alive, a former colleague, and suspect foul play, but without a body, the investigation hits a dead end. They call on expert witness and soil scientist, Professor Lorna Dawson, to help them locate where Emma鈥檚 remains may be.

Soil analysis from the suspect鈥檚 shoes and car point to a remote location in the Galloway Forest Park, and Lorna is able to direct police teams to Emma鈥檚 location. With revealing interviews from Professor Dawson, retired chief superintendent Paul Dockley and 91热爆 Scotland鈥檚 Catriona Renton.

In 1997, the body of Tracey Wylde is found in her Glasgow flat after she failed to turn up for an appointment. The 21-year-old mother of one was a sex worker in the city centre. She had been strangled and bitten on her chest. Although police manage to recover DNA from Tracey, there鈥檚 no match on any of their databases, and the case goes cold.

Twenty-one years later, a match is made with a man arrested for an unrelated offence, but in order to prove he is guilty of Tracey鈥檚 murder, police call on odontologist Dr Douglas Sheasby to try and discover if the bite mark on her chest could be linked to the suspect. Faced with overwhelming evidence against him, the suspect pleads guilty and is sentenced to life.
