What happens in Chapter 25 of The Secret Garden?
Chapter 25, "The Curtain," represents a significant turning point in Frances Hodgson Burnett's The Secret Garden. Colin, after spending weeks in the walled garden with Mary and Dickon, is noticeably changing—his body gaining strength, his mood improving, and his fixation on illness fading. In this chapter, Colin makes a bold decision: he plans to keep his recovery hidden from his father, Archibald Craven, who is still away on his travels. The children come together to hide Colin's impressive physical improvement from the household staff, especially the skeptical Mrs. Medlock and the well-meaning but intrusive Dr. Craven. Colin pretends to be weak indoors while flourishing outside, creating a curtain—both literal and metaphorical—between his public invalid persona and his secret, thriving self. Dickon's mother, Susan Sowerby, quietly supports the effort, sending extra food to fuel the children’s outdoor activities without raising the adults' suspicions. The chapter ends with a growing sense that this secret can't last forever, and that the garden's magic is building toward a moment that must ultimately be shared with Archibald Craven himself.
Analysis
Burnett's craft in "The Curtain" skillfully balances two themes: concealment and revelation. The titular curtain serves not just as a prop but as a central metaphor, symbolizing the thin barrier between Colin's public persona and his true self. With quiet precision, Burnett employs dramatic irony; readers witness the servants being fooled by a boy who has perfected the act of sickness, having once believed in it so completely.
The tonal shift in this chapter is striking. Earlier sections were steeped in the anxious, gothic atmosphere of Misselthwaite Manor—locked rooms, night-time wails, and the scent of damp stone. In contrast, Chapter 25 radiates a conspiratorial warmth, almost comical as it depicts Colin sneaking food and then pretending to have a poor appetite during meals. This lightheartedness highlights Colin's remarkable transformation; the boy who once ruled the household through his suffering now subverts it with his newfound health.
Susan Sowerby's offstage presence is a notable aspect of Burnett's craft. Though she never appears directly, her moral influence grounds the children's scheme in something more significant than mere mischief—her subtle support indicates that nature, community, and maternal wisdom stand against the sterile adult world of doctors and diagnoses. The motif of growth as a form of secret knowledge, first introduced with Mary's discovery of the garden, comes to full fruition here: what is alive must be safeguarded until it is strong enough to face the outside world.
Key quotes from Chapter 25
“'I am going to make an experiment,' said Colin. 'I am going to try to be well.'”
Colin announces his intention to the other children in the garden, framing his recovery in the rational, scientific language he has absorbed from his father's world—a telling sign of how he is integrating his new self with his old identity.
“'We must not let them find out,' said Mary. 'If they find out now it will spoil everything.'”
Mary articulates the children's shared instinct to guard the garden's transformative work, voicing the novel's central tension between the secret world of growth and the intrusive scrutiny of adult authority.
“He had been afraid of it so long that the habit of fear was not easy to break, though the fear itself had almost gone.”
Burnett's narrator reflects on Colin's psychological state, distinguishing between the emotion of fear and its ingrained behavioural patterns—one of the novel's most psychologically precise observations.
