Peter (Bobbi and Gard’s dog)
The TommyknockersPeter (Bobbi and Gard’s dog) is a beagle whose responses to the buried spacecraft make him an early warning of its influence and whose fate later exposes the moral cost of Bobbi’s transformation. Once a beloved companion, he becomes a source of power in Bobbi’s shed, his altered existence bound to the green light and to the suffering Gard cannot accept as a necessary price of survival.
Early Warnings
When Bobbi first uncovers metal in the forest soil, Peter approaches, sniffs it, then backs away, sits, and gives a single low howl. His reaction is striking because it is unlike an ordinary response to an unfamiliar object: the dog seems to register a danger that Bobbi has not yet understood. She continues examining the metal, but Peter’s withdrawal gives the discovery an animal witness.
The landscape soon supplies other warnings. Bobbi finds a dead woodchuck without flies around it and later comes upon five dead birds—sparrow, crow, another crow, bluejay, and scarlet tanager—near the trench. None shows an obvious mark, and there are no flies at their bodies. Bobbi considers whether the buried object could be responsible, but resists drawing that conclusion. The accumulating animal deaths and Peter’s behavior nevertheless establish that the spacecraft’s presence is not only a human problem.
Fear, Aging, and Attachment
Peter’s condition becomes harder for Bobbi to dismiss. In a veterinary ward, his growl turns into a snarl when a doctor leaves, and Bobbi has to seize his collar to stop him from pursuing the man. She recognizes the response as rage rather than fear, and the intensity seems utterly unlike the dog she knows. She can entertain the possibility that the spacecraft has killed a woodchuck, and accept other changes in herself and Peter, but cannot bear the possibility that Peter’s eyes show hatred toward her.
The contrast is sharpened by signs that Peter has been growing younger and that his cataract is in remission. Improvement, however, does not mean safety: he remains physically and behaviorally altered, and his early response to the buried metal is followed by unexplained animal deaths. The dog is thus both a companion Bobbi loves and a living measure of how the buried force unsettles ordinary life.
Bobbi’s Work and Gard’s Discovery
Later, Gard finds Peter in Bobbi’s shed, connected by wires to a device and enclosed in a liquid-filled apparatus. The sight makes clear that Peter has become part of the machinery sustaining Bobbi’s work. Gard’s immediate response is not to treat the apparatus as a technical marvel: he is horrified that Bobbi has subjected their dog to it and wonders why she would have put Peter in the shed.
When Gard confronts her, he recalls that Peter would have given his life for Bobbi and contrasts the present arrangement with the earlier days when she could not bear Peter bringing home a dead bird. He also remembers the life they shared at the farm, including the time they stood together against her sister. Bobbi answers that Peter kept her alive while she worked around the clock and that his presence was why Gard had anything left to save when he arrived. Her defense establishes Peter’s importance to her during her isolation, but it does not erase the gulf between her account of dependence and Gard’s perception of exploitation.
Gard’s Priorities and Peter’s Fate
Peter becomes Gard’s first emotional priority at the farm. Gard acknowledges that rescuing David Brown must come first, but David is a boy he has never met; Peter is different because Gard knows and loves him. That distinction shapes the rescue effort as more than a practical mission: Peter’s suffering is an immediate personal obligation, one tied to the shared life Gard remembers with Bobbi.
In the green light, Peter’s condition is described as a radical diminishment of the companion Gard knew. He is identified as the “less-mind” that was once Peter; now he can only howl, sometimes calling for Bobbi to release him, but mostly suffering as he is drained. Bobbi also cries out for release, and her thoughts sometimes turn to hatred. The parallel links their torments without making them equivalent: Peter’s reduced awareness and inability to act leave him dependent on the people and machinery that have trapped him.
Significance
Peter’s arc gives the novel’s technological transformation an intimate, nonhuman cost. The dog’s first refusal to approach the metal, the dead animals around the excavation, and his later conversion into a wired source of power form a progression from warning to victimization. His altered behavior is evidence of the spacecraft’s reach, but his importance is never exhausted by that function: Gard’s memories of their shared home and Bobbi’s admission that Peter sustained her insist that he was a companion, not merely an instrument.
The conflict over Peter also measures the distance between Bobbi and Gard. Bobbi frames the arrangement through survival and the work that Peter helped make possible; Gard sees a betrayal of an animal who loved them both. By making Peter central to Gard’s rescue priorities and to the novel’s account of the green light’s suffering, the story refuses to let the transformation be judged only by what it enables humans to build or endure.
