In Sudan, the persecution of slave traders comes to an end. The Reis Effendina cannot show mercy towards their inhumane cruelty. After an episode set in wild Kurdistan with Hadschi Halef Omar, the "last slave hunt" serves as the conclusion, now back in Inner Africa. This narrative takes place at the end of the 1870s. "In Sudan" is the final part of the trilogy "In the Land of the Mahdi." Other volumes include "Manhunters" and "The Mahdi," also available as an e-book.
