The story opens with a domestic confrontation: Craig Stevens calmly tells his wife Sheila to leave, while she pleads and accuses him of mental cruelty. The scene is set in a laboratory, where a metallic, dog-sized robot lies on an operating table. Craig's cold, clinical demeanor—he regards Sheila with 'the cold objectivity of a lab technician'—immediately establishes him as an emotionally detached inventor. The robot, unnamed at first, is described as 'alive in its own way,' and Craig's focus shifts entirely to it after Sheila departs.

A Marriage Dissected

The opening dialogue reveals the fault lines in Craig and Sheila's marriage. Sheila's language is emotional—'I hate you,' 'I wanted to see you suffer'—while Craig responds with detached sarcasm: 'A celebration would be more in order.' He dismisses love as 'a foolish notion' and admits he was only interested in Sheila's 'spirit' as a subject to study. This dynamic sets up a pattern: Craig treats human relationships as experiments, a trait that will extend to his robot. The excerpt provides no backstory beyond Sheila's complaint of 'mental cruelty,' but the power imbalance is clear. Craig's final laugh, echoing off 'cold stone walls,' underscores his isolation.

The Robot Ohm Takes Over

After Sheila leaves, Craig becomes absorbed in his creation, which he names Ohm. A friend, Beale, visits and urges rest, but Craig dismisses him, saying 'Couldn't leave Ohm.' The robot is described with increasingly ominous details: a 'photo-electric eye twitching nervously,' and later, Craig modifies it with 'razor sharp metal teeth.' A peculiar stain appears on Ohm's teeth, which Craig cannot explain—a detail that foreshadows violence. The narrative notes that Craig's 'every waking hour' is filled with plans, and he dreams of 'blind frenzies of frustration.' The robot's behavior shifts from passive to 'half-pleading, half-threatening,' marking a turning point in their relationship.

Craig's Deteriorating State

As Craig pushes himself, his physical and mental health decline. He feels 'worn out and frazzled,' yet finds the relationship with Ohm 'gratifying'—more complete than his domination of his mother or Sheila. The sessions leave him 'at once weak and god-like.' One night, he forgets to secure Ohm in its hutch, and the robot goes missing. Craig, too tired to search, stumbles to bed. His exhaustion is palpable: 'He couldn't remember ever having been so tired.' The narrative shifts to a dream sequence, where Sheila and a little girl (whose kitten Craig threatened) appear, warning him about the stains. The dream ends with the laboratory collapsing, suggesting internal chaos.

Unresolved Tensions in the Excerpts

The provided text cuts off before the story's climax, leaving key questions unanswered. The dream sequence implies guilt and danger, but the actual fate of Craig and Ohm is unknown. The stains on Ohm's teeth, the missing kitten, and the robot's threatening motion all point toward a violent outcome, but the excerpts do not confirm it. Readers must infer from the mounting dread: Craig's obsession, the robot's autonomy, and the repeated motif of 'rest' (Craig says 'I can rest for a long time') suggest a grim resolution. The story's title, 'Perfect Companion,' becomes ironic in light of these tensions.

These excerpts offer a concentrated view of McGreevey's technique: tight dialogue, escalating unease, and a protagonist whose emotional void is filled by a machine. The story rewards attention to small details—the stain, the missing kitten, the dream imagery—that build toward an implied horror. Readers should note how the narrative withholds information, letting the robot's menace grow through implication rather than explicit action.
