Five intergalactic criminal masterminds raid the tranquil world of Mount Pleasant, leaving behind only ruin and slaughter—and the orphaned child Kirth Gersen, who comes to manhood swearing to take bloody revenge. Now Gersen roams the galaxy, bringing vengeance to the Demon Princes one by one, in Jack Vance's classic series of hardboiled space opera.

The fourth Demon Prince, Lens Larque, combines murderous criminality with a taste for horrific practical jokes. Escaping Gersen once, Larque flees to his home world of Dar Sai, known for its strange mating rituals and the violent winner-take-all game of hadaul. Gersen follows his quarry to the milder world of Methel, where Larque plans a revengeful prank on a wealthy man. Gersen has a more final vengeance in mind.
