With Kevin Thompson now dead in a motorcycle crash, the police continue their investigation. Nikki believes that the dead Gemma - who was pregnant at the time she was killed - was suffering from glandular fever as is her step-brother Charlie. The Thompson's neighbor, 15 year-old Joel, is found sitting by Charlie's bedside at the hospital. He tells Harry he was in love with Gemma but that he didn't kill her or her mother. Stuart is found to have lied to the police concerning his whereabouts on the night his family was killed but the police now suspect someone else altogether for the deaths. The motivation for the murders is found in events from long ago and a family secret few were aware of.
