S01E05: Ghosts - Part 1. The body of a university undergraduate, Josh Tate, is found dumped in a ravine, stabbed with something like a screwdriver. His flatmate, Spencer, says Josh was the quiet type - he last saw him heading off to his part time job at the uni lab. As the team piece together his movements, a picture emerges of another Josh, who was infatuated with his friend Spencer's lap-dancer girlfriend Melanie, and was also manufacturing the drug "ecstasy" for club owner Fallon with the help of his biochemistry tutor. Helen is unnerved by the arrival of former lover Martin Hexton, an undercover officer who claims to be working a case in Yorkshire, just as her own husband Michael reveals he wants custody of their children.
