The Star Sneak

Learning of rumors to the effect that Vulgare Hokum had undertaken certain mercantile enterprises among the highland folk to the east of the city of Astropolis, on Tristan, Garth Curson chartered a star vessel and hurried to the planet. His errand: observance of his vow to enact vengeance upon each of the five Demon Pranksters who had ventured the temerity to address him in colloquial terms-one of whom was Vulgare Hokum... So begins Larry Tritten's sendup of the works of Jack Vance.
