This good early Aldiss sees Earth as a subject colony in a 4 million planet strong empire ruled by the tripedal, bureaucratic race known as nuls. Towler is appointed as interpreter to a visiting nul inspector, investigating charges of corruption and exploitation by Par-Chavorlem, Earth’s colonial administrator, who attempts (successfully) to cover up his misdeeds, portraying his regime as lenient and enlightened in the face of the violent human population, who are engaged in a (faked) civil war (with imported Starjjans, whose importation is a crime). Aldiss had experience of British colonialism and draws his characters well - Par-Chavorlem schemes to no end, and has a habit of terrifying humans to satisfy his detached sadistic tendencies; Rivars plays the naïve revolutionary, eventually turning on Towler as his simple scheme to convince the inspector fails (believing he need only provide proof of Starjjan presence on Earth to the inspector, using a severed Starjjan foot, overlooking the fact that the inspector is unaware of the appearance of Starjjans despite having administered Starjj); the inspector, Synvoret, is the best character - convinced of his own superior intellect and morality, he nevertheless views humans with disgust and finds himself duped by the facade he is presented with, eventually aiding the human cause by providing evidence of Chav’s excessive lenience for allowing an attempt on his life to be made in an ironic, humorous ending that works well in underlining the inefficiency of the decaying empire. The book’s message is clear: diplomatic attempts to resist imperialism are futile - the administrators don’t care, they have no connection to the culture and no understanding of the people, so only violence will prevail. The world-building is adequate, with a couple of nice touches, such as the wronged gambler Wattol Forlie who blags some change off Synvoret to win his sip fare home, and the weird 4D ‘Jarmboree’ sex film Towler is forced to experience and which foils the attempt on his life. The prose is solid and the narrative whips along, although it does get a bit formulaic and a tad aimless around the middle.
