That night a little son was born in the tiny cabin beside the primeval forest, while a leopard screamed before the door, and the deep notes of a lion's roar sounded from beyond the ridge.
Lady Greystoke never recovered from the shock of the great ape's attack, and, though she lived for a year after her baby was born, she was never again outside the cabin, nor did she ever fully realize that she was not in England.
