The story unfolds as a series of encounters between Broadhead and Sigfrid that ultimately result in Robin coming to terms with his guilt.
Beyond the Blue Event Horizon introduces a much more sophisticated program modeled on Albert Einstein. It serves as an information processor for Broadhead. Broadhead’s wife continues to upgrade the Albert program, which eventually has a profound crisis when it is forced to accept the validity of quantum mechanics. In Heechee Rendezvous, Broadhead dies, and his wife reads his personality and memory into machine storage, where he is then free to interact with other, similarly stored individuals. In this cybernetic reality, Broadhead can simulate experiences such as skiing, drinking, or making love, and do so in conjunction with others. In The Annals of the Heechee, the Assassins are revealed to have far more in common with these machine-based entities than with organic life. The final two novels directly address the question of the nature of intelligence and life.
