The Dosadi Experiment

by Frank Herbert

The novel is set in a distant future when humans are part of an interstellar civilization called the ConSentiency composed of many species. One, the Taprisiots, provide instant mind-to-mind communication between two sentient minds anywhere in the universe, and the Caleban provide "jump-doors" (which allow instantaneous travel between any two points in the universe). This is the glue that holds the far-flung ConSentiency together. Unfortunately, one consequence of jump-door technology is the possibility that large numbers of unsuspecting sentients can be diverted to destinations unknown for nefarious purposes. A government saboteur attempts to expose one such plot.

Jorj X. McKie is a Saboteur Extraordinary, one of the principals of the Bureau of Sabotage, and the only human admitted to practice law before the Gowachin bar as a legum (lawyer). While meditating in a park in the Bureau's headquarters, McKie is mentally contacted by the Caleban Fannie Mae, a female member of a multidimensional species of unparalleled power whose visible manifestation in this universe is the star Thyone in the Pleiades cluster.

Generations ago, a secret, unauthorized experiment by the Gowachins was carried out with the help of a contract with the Calebans. They isolated the planet Dosadi behind an impenetrable barrier called "The God Wall". On the planet were placed humans and Gowachin, with an odd mix of modern and old technology. The planet itself is massively poisonous except for a narrow valley, containing the city "Chu", into which nearly 89 million humans and Gowachin are crowded under terrible conditions. It is ruled by a dictator, many other forms of government having been tried previously, but without the ability to remove such things as the DemoPol, a computer system used to manipulate populaces without their consent or knowledge. The culture of ordinary day-to-day power in Dosadi is very violent. Among other tools, addictive psychotropes are used for handling power among hierarchies in organisations.

Senior Liator (or Liaitor) Keila Jedrik starts a war that will change Dosadi forever. Jorj travels to Dosadi and escapes with Keila after engaging in ego sharing. This gives them the ability to swap bodies and thus by using a hole in the contract sealing Dosadi they can escape via jump gate. Once free, by legal manoeuvring the Dosadi population is unleashed upon the ConSentiency for good or ill, while the people who set the project in motion try to deal with the consequences, having sent McKie there hoping a solution more in their interest could be found.
