A Fifth Doctor Audio Adventure on a double CD starring Peter Davison, with Sarah Sutton as Nyssa.
One wouldn't normally expect to find elephants, gorillas and rhinoceroses roaming free in Suffolk in the year 1911. One wouldn't normally expect to find an extra-dimensional police box at the same time/space location either. Two aliens, named the Doctor and Nyssa, exit said box, only to find themselves pursued by a hungry lioness – for they've landed in the private hunting grounds of the famous explorer Nathaniel Whitlock, who's brought together a motley group of friends and acquaintances for a weekend's shooting. But one of Whitlock's guests isn't all they seem. One of them wants the secrets of the Moonflesh, the mystic mineral looked after by Whitlock's retainer, a Native American known as Silver Crow. Because the Moonflesh is reputed to have the power to call down spirits from another realm… and soon, the hunters will become the hunted.
