The Unteleported Man (later republished in a greatly expanded version as [Lies, Inc.]) is a 1966 science fiction novel by American writer Philip K. Dick, first published as a novella in 1964. It is about a future in which a one-way teleportation technology enables 40 million people to immigrate to a colony named Whale's Mouth on an Earth-like planet, which advertisements show as a lush green utopia. When the owner of a failing spaceship travel firm tries to take the 18-year flight to the colony to bring back any unhappy colonists, powerful forces try to stop him from finding out the truth.
