Let a closely watched character gain room to act by encouraging the watcher to expect the wrong kind of disobedience.
The breakfast incident, the garden distraction and entry into the storage room. The aunt's later predicament and the ending are not described.
Nicholas has deliberately put a frog in his breakfast, proving the adults wrong when they insist there cannot be one. His cousins' aunt, who also calls herself his aunt, keeps him home as punishment while the other children go to the seaside. She forbids him to enter the gooseberry garden. He has a different wish: to explore the locked storage room full of objects the children are not allowed to see.
Nicholas lets his aunt see him creeping toward the garden entrances. His aunt concludes that he means to defy her order and spends much of the afternoon watching the two doors. The narrator tells us that he never intended to enter the garden. Once he has strengthened her suspicion, he slips indoors, reaches the storage-room key from a chair and opens the lock. He has spent several days practising how to unlock the schoolroom door. While he explores pictures and objects inside, his aunt interprets his absence as proof that he has got into the garden and searches there.
The watcher should have a reason to focus on the wrong place, not simply become inexplicably careless. Here the aunt has issued the prohibition and is determined to enforce it; Nicholas exploits that determination. The narrator discloses his real intention before he enters the room, so the scene's pleasure is watching the plan work, not discovering his goal in a final twist.

Complete English short story checked in Project Gutenberg ebook 269, transcribed from the 1914 John Lane edition. The aunt's assumptions and Nicholas's preparations are explicit in the narration. The explanation of their writing use and the scene-planning exercise are CueShelf's editorial guidance.
Nicholas does not need his aunt to stop watching him altogether. He needs her to watch one place. She already expects a child in disgrace to defy a new prohibition, so his visible approaches give her a reason to stay by the garden. Her effort to prevent one act leaves him time to carry out another. His preparation with keys matters too: the distraction creates an opportunity, but an established skill lets him use it.
Plan a scene with someone who has the power to stop your character. Write down two different aims: what this person expects the character to try, and what the character actually needs to do. Give the expectation a reason in their earlier dealings. Then write a visible action that appears to confirm it, followed by the watcher's specific attempt to prevent it. That response must leave a usable opening for the real task: a place left unwatched, time alone with someone, or a message left unchecked. Establish the contact, access or skill your character needs before the opening appears. Finally, decide what could make the watcher reconsider. The scene should depend on a mistaken belief, not just on finding someone a time-consuming chore.
Use in my storyExpose a boastful character through an ordinary shared task, then let them become the irritating spectator they were just complaining about.
A small promise puts the protagonist in the right place to survive a disaster and leaves them badly equipped for what follows.
A recurring argument needs more than another order to behave. Let a character identify the small, specific attraction behind it.
