As the team examine the forensic evidence at Henderson's house, Sandy discovers the body of John Henderson by the roadside, brutally murdered. When Willow Reeves subsequently discovers paint at the site, similar to that found in Jerry's car, Perez decides to proceed on the basis that the two deaths are linked. While Reeves conducts the autopsy on Henderson's body, determined to find the type of murder weapon used, Perez is paid a surprise visit by a woman claiming to be Jerry Markham's fiance. She gives Perez a memory stick sent to her by Jerry for safekeeping before his death. On it, Perez discovers anonymous emails that confirm potential corporate corruption by Storne Gas, as well as Jerry's own personal investigation into Joe Dalhousie's claims of foul play by the gas company to force him off his land. Additionally, there are incriminating photos of John Henderson with Evie's best friend -- Jenny Belshaw.

While interviewing Jenny, Perez is intrigued to discover that Jerry desired John's help in some way, and was apparently trying to blackmail him to force his hand. Perez speculates if anyone else knew about Jenny's affair with John? Jenny denies this, but the spotlight shifts to Jenny's husband, Andy Belshaw - a man who disliked Jerry professionally and could potentially have a personal motive to get rid of Henderson. However, lines of enquiry against Belshaw are soon closed down when he provides an alibi for the night that Jerry died. No closer to finding a clear lead, Perez decides that the answer must somehow rest with Evie Watt, as she was close to both victims. The investigation into Evie uncovers just how desperate she was to get away from her overbearing father, but she continues to deny any involvement in the two murders. Perez is running out of answers and time. When he re-examines some of the photographic evidence though, and Willow Reeves finally determines the murder weapon used, everything falls into place. A hidden past is uncovered. The true nature of Jerry's story revealed. And a motive to kill two men finally exposed.
