The Curious Case of Natalia Grace has gripped viewers as the story of an alleged six-year-old Ukrainian child's adoption by an American family unfolds on screen.
Natalia Grace was said to be six years old when she was welcomed into the Barnett family home in Indiana in 2010, but her age was soon doubted by her new parents Michael and Kristine.
They claimed the youngster, who has a rare bone growth disorder called spondyloepiphyseal dysplasia, was actually an adult at the time of adoption and said she went on to threaten to kill them family - claims Natalia continues to deny to this day.
