Lyn and Chris Dawson's life was perfect. He was a teacher and footballer, she was a devoted mother and wife. Lyn disappeared. Did she walk out, or did something sinister happen?

Cromer students knew Mr Dawson was having sex with his teenage student. When she moved into his home just days after his wife Lynette disappeared, no-one raised an eyebrow.

Lynette's loved ones push unsuccessfully for her disappearance to be properly investigated. The case stalls until 16 years later when detective Damian Loone is assigned.
