Playwright Simon Stephens . . . not only frames the action, but also sets up a rich tension between fiction's invention and the obsession with facts, forensics and systemised data that is a symptom of Christopher's autism . . . this is a highly skilful adaptation

Michael Billington, Guardian

A curiously successful case of a hit novel turned into a play . . . This is a profoundly moving play about adolescence, fractured families, mathematics, colours and lights

Michael Coveney, Independent

This adaptation by the acclaimed playwright Simon Stephens is intensely, innately theatrical; it is also funny and extremely moving

Laura Thompson, Daily Telegraph

Seeing an adaptation of a book that you have loved can inspire a certain nervousness but fans of A Curious Incident should have no such worry when going to see the National's faithful and imaginative adaptation. It is a triumph, capturing the depth and touching nature of the original text and adding theatrical sensibilities to great effect. Highly recommended.

Londonist

As adaptations of much-loved fiction go, Simon Stephens' perky and imaginative version . . . is an instant classic

What's On Stage

Simon Stephens' clever adaptation of Mark Haddon's bestselling novel about a teenage boy with Asperger's syndrome is like a cute dog that leaps up and wants to lick you all over. There's no point in resisting – and there's no need ... The novel gets you inside Christopher's head, but the stage version does more, giving Christopher's internal response to the world an external manifestation.
