Revision Note

Plot Summary

One of the most helpful things you can do in preparation for the exam is to “know” the plot of The Curious Incident of the Dog in the Night-time thoroughly. This way you can track the way themes are presented, or how characters develop. Having an in-depth knowledge and understanding of the play will help you to understand how dramatic methods and theatrical techniques have been used to convey key ideas. 

Below you will find:

  • a general overview of the whole play

  • detailed summaries by act

Overview

The Curious Incident of the Dog in the Night-time, adapted from Mark Haddon’s novel into a play by Simon Stephens in 2012, is considered a Bildungsroman. Fifteen-year-old Christopher Boone’s life-changing experiences are presented through the narration of his book, read by his teacher while events are acted out on stage. Settings shift constantly to reflect the protagonist’s turbulent emotional and physical journey.

The play opens in a garden at night-time. Christopher stands over his neighbour’s dead dog, Wellington, who has been stabbed with a pitchfork. Against his father’s instructions, Christopher decides to solve the mystery of who killed Wellington. When questioning his neighbours, Christopher is given confusing information by Mrs Alexander. Back home, he finds hidden letters from his mother, Judy, who he believed was dead, and learns that Judy is in London with their old neighbour, Mr Shears. When confronted, his father, Ed, admits that, after arguing with Mrs Shears (with whom he had become close), he killed Wellington in a rage. 

Christopher boards a train to live with his mother. But the journey is overwhelming: Siobhan’s reading details how the lights, noise and crowds lead to anxiety attacks on Christopher’s way to London. His autism spectrum disorder is not identified in the play, and thus draws attention to the ignorance surrounding the condition. 

Christopher’s arrival causes arguments between Judy and Mr Shears, and, as he cannot do his A Level mathematics exam in London, Christopher insists he and his mother return to Swindon. 

At home, Judy and Ed apologise for their mistakes and Christopher takes his examination. The play ends as Christopher receives an A-star grade and informs the audience he is capable of anything.

Examiner Tip

Knowing the plot of the play well is important, but it is equally important to pay attention to the setting changes that Stephens uses to convey the dramatic developments of the story. These give extra information about the action and the characters, which will help you to develop your own insights and interpretations about the play.
