A Killer Makes a Call

When 34-year-old Debbie Griggs went missing from her family home in Deal, Kent, her husband Andrew insisted something was deeply she had simply walked out, leaving her young children behind. Despite exhaustive searches and years of painstaking investigation, Debbie's fate remained a mystery, her body never found, leaving the police unable to prove what they suspected was Griggs's guilt. Across the next two decades, successive teams of detectives continued to build the evidential, compiling and corroborating key testimony, including proof of Griggs's illicit relationship with a 15-year-old girl at the time of Debbie's disappearance. As the accumulated evidence was re-examined, it became clear that Debbie had been murdered, even though her body had never been found. Through powerful interviews with the officers who refused to give up, and the family who lived through decades of uncertainty, this film charts the extraordinary investigation that spanned 20 years and the moment the truth was finally unearthed
