On Monday 28th December 1992, Steven Clark vanished without a trace from his home town of Marske-by-the Sea in North Yorkshire.

Twenty-eight years after Steven’s disappearance, following a cold case review in September 2020, police arrived at the home of Charles and Doris Clark aged 78 and 81 years respectively. They arrested the elderly couple on suspicion of their son’s murder. Following the arrest, police officers intensely searched the local area and conducted a 5-day forensic examination of the Clark home, digging up their garden in the search for Steven’s body.

Is this simply an unimaginable nightmare for a totally innocent couple, or are Doris and Charles killers?

With incredible exclusive access, Mark follows this gripping case as it unfolds in real time, leading to the point where Doris and Charles Clark find out if they will be released without charge or jailed for their son’s murder.
