A dead dog, a math genius, and a stage that explodes into his mind.
Christopher, fifteen years old, has an extraordinary brain – exceptional at maths while ill-equipped to interpret everyday life. When he falls under suspicion of killing Mrs Shears' dog Wellington, he records each fact about the event in the book he is writing to solve the mystery of the murder. But his detective work, forbidden by his father, takes him on a frightening journey that upturns his world.

Trivia, insights & behind the scenes
The original novel was written in Christopher's voice with no chapters — only prime numbers. The play preserves this through Siobhan reading his 'book' aloud.
This 2012 NT Live recording preserves Luke Treadaway's Olivier-winning performance before he aged out; the role's now rotated every few years to maintain authenticity.
