Sepultura by Guy Portman is an adventure in writing for Portman. The author bends a lot of rules as far as the mechanics of English. The novel is an adventure in reading as the reader constantly tries to figure out who some of the characters are. In tandem with this, Portman makes liberal use of a street-level British vernacular. This novel offers much to the education of readers without knowledge of this language form. Main character Dyson Devereux is probably immoral and definitely amoral as he goes about justifying his killing of other characters who give him problems. The descriptions of the killings are graphic as are descriptions of sex scenes which are obviously power, not sexually, motivated.
