The Corridors of Time alternates between the European Stone Age and a repressive future. In its vision of tomorrow, almost everyone is either an agricultural serf or an industrial slave, but the rulers genuinely believe that they are creating a better world. Set largely in Denmark, it treats the Neolithic society with knowledge and respect but does not hide its own faults. It is there that the protagonist, having access to literally all periods of the past and future, finally decides to settle down and finds a happy and satisfying life.
