The dam half-built, the fat rains came, and the Zambezi rose up and charged. It knocked the dam aside and swallowed some workers. The Tonga said, ‘Nyami Nyami is hungry.’ They killed a black calf and threw it in the river and the bodies washed up where it vanished. The feckless bazungu continued building the dam. When the flood came again, it lifted four men, plastered them to the dam like insects. The concrete was wet; the workers were dead; in the end, they built the dam around them. Strange tomb!
