The Eyes of Heisenberg
Frank Herbert
 Chs. 1-4: Harvey and Lizbeth Durant arrive to witness the cutting of their embryo. Svengaard, a low-ranking doctor, tries to convince them to skip the procedure, but they are adamant and insist on their right, all the while secretly communicating their contempt for Svengaard in a silent Courier code. Potter, a high-ranking surgeon, arrives to perform the cut. During the procedure, he is shocked to discover that the embryo has qualities not seen in millennia; superior genetics in the areas of intelligence, plus vocation for immortality and full fertility. Obligated to destroy it, Potter is surprised to find himself unwilling to do so, aided by the on-the-spot collusion of one of the nurses who sabotages the record of the operation. Ch. 5: Max Allgood, Boumard and Igan arrive at the Hall of Counsel for an audience with the Tuyere. Tachy-Security monitoring has detected something amiss with the Durant embryo cutting. The nurse has been arrested, but has died under interrogation. The Optimen Calapine, Nourse and Schruille playfully mock their subordinates, always with a faint undercurrent of menace. Calapine flirts with Allgood in a semi-bemused fashion. The Tuyere order that Svengaard be brought before them. Boumard and Igan are revealed to the reader as Cyborg agents. Ch. 6: Svengaard is interrogated by the Tuyere. Badly frightened, he fumbles and grows agitated under their mockery, becoming insubordinate. The Tuyere calm him down by a display of magnanimity, reminding him of their power, wisdom and seniority. Ch. 7: In a service area under the Seatac Megalopolis, the Durants have gone into hiding. They meet with the Cyborg Glisson, who informs them of events, tells them that a strange external force had (beneficially) interfered with the cutting process of their embryo, and orders them to stay put. The Durants chafe under its unfeeling, domineering manner, hoping to one another to one day be free of the Optimen and Cyborgs. They scheme to deliver their baby the unheard-of natural way, and keep it out of reach of both. They wonder if the interfering power is God. Ch. 8-9: Svengaard detects activity in the hospital vat room, where the embryo is kept. Investigating, he is rendered unconscious and abducted from under the nose of Max Allgood's surveillance. Ch. 10-11: Potter is escorted through the streets of Seatac by a resistance agent. Near their destination, they are intercepted by security forces. Potter's escort sends him ahead, revealing himself as a combat cyborg and decimating the pursuers until it is destroyed. Potter is spirited away by the resistance. The Tuyere - and many other Optimen - watch the battle live, the long-unfamiliar thrill of violence awakening odd sensations in them. Ch. 12: In a resistance safehouse, Igan tries to recruit a recalcitrant Svengaard. Failing, they sedate him and make plans to evacuate Seatac, which they suspect the Optimen are about to genocidally purge of all life. Ch. 13: The Durants, Boumard and Igan (their cover blown) and a gagged Svengaard are moved out of Seatac in a hover-truck driven by a Cyborg, later revealed to be Glisson. At a checkpoint, Svengaard cries out briefly, causing them to be traced. Glisson changes their destination. Ch. 14: The Tuyere wipe out Seatac through a combination of poison gas and sonic weapons. They find themselves surprised by their unstable emotional reactions to the event. Ch. 15: The occupants of the truck observe the destruction of Seatac; Svengaard's faith in the Optimen is badly shaken. The Durants notice that Boumard and Igan are in the early stages of cyborgization. The truck proceeds to a ramshackle safehouse in the forest. Ch. 16: The Tuyere receives a field report from Max Allgood. Calapine, growing suspicious of his behavior, scans him with her instruments, discovering that he has accepted Cyborg implants. Enraged, she kills him remotely. Calapine and Schruille decide to run Tachy-Security themselves, finding themselves oddly stimulated by the prospect of an even more active involvement in violence. Potter is revealed to have died offstage in Seatac. Calapine and Nourse both require treatment for enzyme imbalance. Ch. 17: The occupants of the cabin decide that the apathetic Svengaard cannot be trusted, and should be killed. Harvey asks him if he wants to live; Svengaard suddenly finds that he does. He offers to care for the Durant's child, an offer Harvey accepts as he does not trust the cyborgs Boumard and Igan. The security forces of the Optimen surround the house and disarm Glisson. Ch. 18: The Tuyere debate what to do with the prisoners. They speculate that, if the infection of viability spreads, wiping out all the Folk and starting over is not out of the question. They decide to have the prisoners brought to themselves for interrogation. Ch. 19: A full assembly of Optimen meet in the Hall of Counsel. The prisoners are brought in, immobilized in a solid block. The Optimen begin to feel odd emotions, spiraling into greater and greater instability. Glisson asserts that reintroducing them to firsthand violence was a Cyborg ploy to destabilize the delicate equilibrium of the Optiman mind, and that the Cyborgs have won. A semi-hysterical Calapine converses with the prisoners, verging on killing them, but abruptly releases them instead. The Optimen descend into insanity; several, including Schruille, are killed in a stampede. The former prisoners try to help. Ch. 20: Calapine and the former prisoners discuss the new status quo. Glisson's gloating is cut off when a biological solution is proposed. Svengaard thinks that he will be able to stabilize the Optimen, and introduce the beneficial mutations of the Durant embryo on a wide scale, giving the Folk a lifespan of at least 12 - 15,000 years - longevity without the pernicious ossification of immortality. The novel concludes on a note of guarded optimism.
