Hilly Brown and David Brown
The TommyknockersHilly Brown and David Brown are devoted brothers whose affectionate, protective bond is shattered when Hilly makes David the subject of a disappearance trick. David’s trust in his older brother helps him step onto the platform despite his fear; when the machine makes him vanish, that same intimacy turns Hilly’s moment of triumph into guilt, panic, and a family catastrophe.
A Protective Bond
Hilly’s parents initially hesitate to leave him alone with the new baby, but they gradually relax as his love for David becomes unmistakable. The brothers’ affection is not merely a family expectation: it is a reliable part of Hilly’s character. His misadventures generally begin with an earnest wish to help his parents or improve himself, even when his efforts go wrong. With David, who idolizes his older brother, Hilly seems to get things right. Ev Hillman considers them so well matched that he says they could camp together for two weeks in the Allagash and return unharmed, because Hilly loves the boy and is good with him.
That history makes the disappearance trick a rupture rather than an extension of ordinary sibling teasing. Hilly has been willing to experiment with making things disappear, but David knows the final act is different: Hilly has never made anything living vanish. David understands the danger even though no one has explained the trick to him. His fear is visible, but his trust in Hilly is stronger than his resistance.
The Final Trick
At Hilly’s magic show, he calls David forward as the volunteer for his final trick. David approaches with fear and resignation in equal measure and whispers that he does not want to take part. Hilly insists. When David points out that Hilly has never disappeared anything alive, the younger boy’s tears spill over. Hilly looks at the brother he loves and briefly recognizes the horror of what he is doing: he does not know where the vanished things go, and David could be exposed to something beyond his control.
For a moment, Hilly’s affection and judgment contend with his resentment toward an inattentive audience. He stops seeing David’s frightened tears and orders him onto the platform. David obeys the brother he has idolized throughout his short life, though his pudgy legs barely hold him as he steps onto the sheet-covered orange crate, with the strange machine concealed underneath. In blue shorts and a faded T-shirt reading THEY CALL ME DR. LOVE, David faces the audience in tears. Hilly tells him to smile and presses the sewing-machine pedal.
The act works: David disappears. Hilly cries out his triumphant finale, caught between victory and fear, while the audience’s apathy briefly breaks. The sudden absence makes the device’s material power impossible to treat as harmless stagecraft. What had seemed to Hilly like a trick is now an irreversible event involving a living child, and the brother who trusted him is no longer there to answer him.
Guilt, Fear, and the Search
After Ev Hillman leaves, Hilly’s guilt and misery intensify. He returns to the platform, presses the concealed pedal again, and waits for the sheet to rise into David’s shape. He imagines revealing his brother beneath it and scolding him for being frightened. But the expected return never comes. The machine’s failure to restore David turns Hilly’s performance into an ordeal of helpless waiting.
His fear becomes concrete when he imagines David stranded on an alien, airless world: a cold, cracked landscape beneath a black sky crowded with brilliant stars, where David is choking and freezing. The imagined scene makes clear what Hilly had scarcely considered before: the things he made disappear might have gone somewhere, and that place may be lethal. Panic overwhelms him before he can act on the thought.
Hilly faints when his father demands to know where David has gone and never really regains consciousness. More than a hundred people, including Bobbi Anderson and Jim Gardener, search the woods across the road for David. The searchers look outward, but Hilly’s unspoken understanding points much closer to home: the danger lies in what happened on the platform and in the device beneath it. His brother’s disappearance is not a voluntary separation or an ordinary missing-child mystery; it begins with Hilly’s own act and the machine’s apparent power to send David elsewhere.
The Relationship’s Reversal
The scene’s deepest reversal lies in the way Hilly’s strongest virtue becomes the source of his most devastating failure. His love for David had distinguished their relationship from Hilly’s otherwise troublesome experiments. David’s devotion, in turn, makes him obey at precisely the moment he most needs protection. The trick depends not only on a device but on a bond: Hilly can bring David onto the platform because David trusts him.
Once David vanishes, Hilly’s earlier confidence gives way to shame, fear, and collapse. The relationship remains emotionally present in his desperate attempt to make the sheet rise again and in his imagined vision of David suffering far from home. But the brothers’ ordinary pattern—Hilly leading, David following—has become dangerous. David is missing, Hilly cannot explain or reverse what he has done, and the family’s search begins under the shadow of that broken trust.
