D Is Caught Peeping and Punished by the Piano Teacher

D Is Caught Peeping and Punished by the Piano Teacher follows the reversal of D’s confidence in looking unseen: the homemade periscope that once makes the world seem welcoming becomes the instrument through which he is exposed. The episode moves from cautious observation of the street to voyeurism at a neighboring toilet, then to an encounter in which the piano teacher makes D confront the embarrassment his intrusion has caused. Its decisive change is not a physical contest but a shift in who controls the gaze and sets the terms of the encounter.

The Periscope and D’s Changing View of the World

D is introduced as a boy who longs to be strong but does not know how to become so. He responds by constructing a periscope from plywood, cardboard, and mirrors: two parallel mirrors, each set at a forty-five-degree angle, transfer his eye to the far end of a horizontal or vertical tube. A cord lets him alter the angle of the upper mirror. The device gives him a way to look from concealment, but at first it also exposes how vulnerable he feels to being looked at in return.

During the first test, D crouches in a narrow space between an apartment fence and shed, a childhood hiding place. When the street appears in the mirror, he imagines its view as a field of reproachful eyes. He ducks, striking and breaking the projecting end of the instrument against the fence, then repairs it with cellophane tape. On a later attempt he holds his ground. As his fear of the imagined reciprocal gaze fades, so does his guilt, and the scene changes in his perception: pedestrians seem free of hostile expressions, the street’s hard edges soften, and the world appears to smile back at him. Looking through the periscope seems to promise an easy peace with the world, but that confidence depends on D’s belief that he can look without being seen.

From Observation to Intrusion

Encouraged by the apparent safety of the device, D begins moving from place to place to look at the street. He then chooses a more private target: the toilet of a nearby cottage associated with a woman who teaches gymnastics at a Middle School and sometimes plays piano there. D is unsure whether she lives in the cottage, and he does not try to clarify that uncertainty. Instead, he links the sound of the toilet flushing with the final piece she habitually plays. The juxtaposition becomes part of his anticipation, and he treats his spying as an adventure rather than as an intrusion into another person’s privacy.

D waits until his mother is out and the teacher has begun her familiar final piece. When the periscope proves too short to reach the cottage window from his own side of the fence, he slips beneath the fence and squeezes into the damp, less-than-two-foot space beside the building. A small opening in the toilet’s dust vent lets him use the instrument horizontally. Yet the view will not settle at the angle he needs: the image shifts from side to side, and he has to work out how to rotate the tube to look up and down. The apparatus that had seemed to offer effortless command over a scene instead leaves him hidden, cramped, and unable to control what he can see.

Discovery and Reversal

As D waits for the music to end, his attention narrows around the expected moment. The piece seems unusually long; he becomes increasingly agitated and begins to imagine entering the house and stopping the piano. The music finally reaches its closing bars, but before the hoped-for view arrives, a voice sounds beside him and demands to know who he is and what he is doing. D has been discovered, although he cannot immediately tell from where the teacher has seen him. The periscope has not protected him from observation; it has helped bring him to a place where another person can confront him.

The teacher directs D to go around to the entrance, bring the strange device with him, and come inside rather than run away. Her instructions make clear that the encounter is now governed by her terms. D considers whether obeying may spare him a report to the school or his parents, and goes to the door carrying the periscope against his chest. Inside, he enters a music room with a piano. The teacher comes in after finishing in the toilet and locks the front door. The scene that D had tried to observe without being noticed has become a face-to-face reckoning, with the instrument that enabled his concealment now present as evidence of what he did.

Punishment and Recognition

The teacher tells D that his conduct has caused embarrassment and that she wants him to experience feelings comparable to those he has caused her. She asks whether he is ashamed, and he admits that he is. Rather than dismiss the incident or leave it at a warning, she turns to the piano and plays the piece he had heard through the wall. D experiences the performance differently from the muffled version that had accompanied his watching; he becomes distressed and cries. The music, previously folded into his private anticipation, now belongs to the teacher’s direct address and judgment.

She identifies the composer as Chopin, then tells D to remove his clothes and says she will wait in the adjoining room. When he hesitates, she invokes the possibility of reporting him to his parents. D complies. The account does not present the episode as a mutual understanding: it shows the teacher imposing a humiliating punishment after catching him in a private space. Her stated purpose is to make him feel something of the embarrassment he imposed on her. Afterward, she asks whether he understands. D nods, and the narration emphasizes that his understanding exceeds what the gesture alone conveys. She tells him to go home, and the key to the front door falls inside for him to retrieve.

Narrative Frame and Significance

The episode is presented as the Case of D within the Box Man Narrator’s larger narration, rather than as an event in the surrounding hospital scene. Its structure turns on a clear progression: the periscope first makes D feel accused by the world, then seems to reconcile him with it, and finally fails to shield him when his looking crosses into another person’s private space. That progression makes the device more than a tool for extending sight. It embodies D’s assumption that observation can be separated from accountability, an assumption the teacher’s discovery overturns.

The punishment closes the episode with recognition rather than with a reported lasting change in D’s life. He acknowledges understanding and is sent home; the evidence does not specify what he does afterward. The narrative then returns abruptly to the Box Man Narrator arriving at the hospital, marking the D story as an embedded case within the book’s shifting account. The shift from D’s imagined peace treaty with the street to the teacher’s demand that he recognize another person’s embarrassment gives the episode its central contrast: a world that seems benevolent when viewed from behind a screen is not thereby consenting to be watched.
