Robert Tallant thought that he was being engaged to accompany the old Count Eisendorf on a scientific expedition to the West Indian Colonies but from the minute that they set foot in Kingston Town the whole journey began to take on the shape of a nightmare.
Guided by the evil Voodoo witchdoctor Blackjoe, the expedition first visits Queen Sabina and on advice that is given in a strange trance they set out to find the King of the Wangamen who lives hidden in the primitive jungles of the Unseeable People.
With death or worse hounding their steps the expedition makes its was through the cannibal filled forests past the evil Lwa spirits and an army of Zombies in search of the Count's ultimate prixe- but what evil is he seeking? And when he finds it can Robert Tallant allow such pure evil to escape into the world?
