Voodoo Planet
by Andre Norton
In the sequel to "The Plague Ship", "Planet Voodoo", "Free Merchant", Dane Thorson appears, who was lucky enough to find work on the ship "Queen of the Sun". Free traders, who travel their trade between the stars, visit known and unknown planets to make a profit. Captain Gaelic and the ship's doctor Tau are invited to the Hutka, a world inhabited by African refugees, to help solve the mystery of the witch doctor's growing power. The grain is invited together as a cover, according to his taste. The hut was created as a special hunting reserve for the rich. The mysterious, possibly supernatural deaths at the hands of otherworldly creatures, lost equipment, and the "magic" of a witch doctor (not to mention poachers!) may be more than the Sun Queen's crew can handle!
