On the 12th November 1976, Renee MacRae, a glamorous 36-year old mother of two and wife of a wealthy building firm owner, vanished after leaving her home in Inverness. Later that night, Renee’s burnt out BMW was found in a lay-by on the roadside of the A9. Neither she nor her three-year-old son Andrew have ever been seen again.
