As well as rebuilding their relationship with their kids while in prison, John and Anne Darwin had grandchildren to meet.
The former couple lied to their own sons with their scheme to fake John's death in a canoe accident in 2002, while Anne played the grieving widow and collected his £250,000 life insurance policy.
Anthony and Mark, who played no part in the audacious con, comforted their seemingly devastated mum while their supposedly 'dead' father was actually sat next door just metres away.
