Rhapsody in Black

Hooded Swan was the best starship in the Galaxy, and Grainger the best pilot. The trip to Rhapsody brought nothing but trouble. The poverty stricken fanatics who lived in its subterranean labyrinths had found a source of riches. In the race for the planet's secret wealth, Grainger found it could destroy civilization. Grainger didn't picture himself and his alien mind-parasite alone in the planet's black depths, pursued by outcasts and rebels - but that was before he became Rhapsody's public enemy number one.
