In the slums of Nairobi there is a place where the fires burn constantly and the stench of decay never fades. Dandora, the city's dumping ground, is filled with shadowy figures the world has left behind. Here too are rumours of the night runners - those said to be possessed by spirits, or the devil. Detective Mollel understands what it means to be an outsider. Born in a Maasai village and forever at odds with the corrupt ranks of the city police, he is drawn to the case of a Fatima, a young girl who has gone missing in the slum. His search takes him deep into Nairobi's underworld, from rap clubs to voodoo healers, and to the lair of the self-styled overlord of Dandora. He learns that Fatima is not the first person to have disappeared, and to find out what has happened to her, Mollel must open his mind to things he cannot see...
