"It was as if nature had turned on its head completely," says Dereck Joubert, a filmmaker who followed Legadema for three-and-a-half years in her natural habitat, the Okavango Delta of Botswana - the verdant flood plains known as Africa's Garden of Eden.
"She had killed the mother primate, but then found this live new-born on the ground. The little baboon called out, and we thought we were going to hear a major crunch and the leopard smacking its lips, but instead the baby baboon put its paws out and walked towards the young leopard.
"Legadema paused for a moment, apparently not knowing what to do. Then she gently picked it up in her mouth, holding it by the scruff of its neck and carrying the infant up a tree to keep it safe."
