The National Theatre's critically-acclaimed staging of The Curious Incident of the Dog in the Night-Time has opened at the Apollo Theatre in the West End.

The book-turned-musical tells the story of 15-year-old Christopher Boone, a maths genius with Asperger's syndrome, who sets out to solve the mystery of who killed his neighbour's dog.
