The story opens with Sophie, a young girl residing in a dormitory, unable to sleep. The environment is described as "absolutely silent," a stillness so profound that Sophie reflects on the concept of the "witching hour." She defines this mysterious time as a period "when every child and every grown-up is in a deep, deep sleep" and when "all the dark things come out from hiding." This setting establishes a haunting, ethereal tone, as the village street outside her window is transformed into a scene that looks "like something out of a fairy tale," with houses appearing "bent and crooked" under a "ghostly pale and milky white" light.
Driven by curiosity, Sophie tiptoes to the window, only to witness an impossible sight. A figure emerges that is "something very tall and very black and very thin." Sophie observes that "it isn't human," noting that it is "four times as tall as the tallest human." The creature’s head towers "higher than the upstairs windows of the houses," leaving Sophie "frozen with fright." This giant figure is cloaked in a "long black cloak" and carries two distinct items: a "very long, thin trumpet" and a "large suitcase."
Sophie watches in horror as the giant stops at each house to peer into the upstairs bedrooms. The narrative details a peculiar and unsettling ritual: the giant places his suitcase on the pavement, extracts a "glass jar with a screw top," and pours its contents into the end of the long trumpet. With a "Woof!" sound, he blows the contents of the jar into Michael and Jane’s bedroom. The ambiguity of what was blown into the room adds to the narrative tension, suggesting a magical or supernatural intervention that Sophie is helpless to stop.
As the giant prepares to move on, he turns his head, and Sophie catches a clear glimpse of her observer. The description is vivid and terrifying: an "enormous, long, pale, wrinkly face with the most enormous ears." His features are sharp, with a nose "as sharp as a knife" and "bright, flashing eyes" that possess a "devilish look." The moment of connection is immediate; the giant’s eyes are "staring straight at Sophie."
Panic ensues as Sophie realizes, "He's seen me!" She attempts to flee back to the safety of her bed, but the giant is faster and more invasive than she could have imagined. The narrative concludes with the terrifying image of that "enormous long pale, wrinkly face" appearing directly at her window. With the giant's "flashing black eyes" fixed firmly on her, Sophie is left in a state of sheer terror, fearing that "he's going to get me." The encounter shifts from a distant, observational mystery to an immediate, personal threat, marking the beginning of a life-altering confrontation between the child and the giant.
