I had high expectations before I went to see The Curious Incident of the Dog in the Night-Time at the Aylesbury Waterside Theatre.

The book is up there with one of my favourites of all time and I have to admit, I was slightly sceptical that the National Theatre production could live up to Mark Haddon’s literary masterpiece.

My scepticism was unfounded, because the show was absolutely brilliant. It was moving, hilarious and perfectly executed by the talented cast.

The award-winning play, starring Joshua Jenkins and Geraldine Alexander, tells the story of 15-year-old Christopher Boone as he goes on a quest to solve a mystery. Intent on discovering who murdered Wellington, his neighbour Mrs Shears’ dog, he records each fact he uncovers in a book. 

But Christopher is unlike most other teenagers; he has an extraordinary brain, and is exceptional at maths but struggles to interpret everyday life -   he has never ventured alone beyond the end of his road; he detests being touched and distrusts strangers, but his detective work, forbidden by his father, takes him on a frightening journey that turns his world upside down.

I have never been more amazed at a leading actor. Joshua Jenkins, who took on the challenging role of Christopher, who has Aspergers Syndrome, played the character perfectly.

His stunning performance left me with tears in my eyes at certain points and his blunt responses had the audience laughing their heads off at others.  

He thoroughly deserved the standing ovation he received from the delighted audience at the end of the show.  

The often difficult relationship between Christopher and his father (played by Stuart Laing) was portrayed excellently and I really believed in all of the characters.

Designer Bunnie Christie has done a wonderful job with the set.  It deliberately comes across as cold and clinical, which reflects Christopher’s love of facts, logic and maths.

The giant box also transforms in a second to depict the sometimes chaotic thought processes that Christopher goes through when he feels vulnerable and it does this without taking too much attention away from the actors on stage.

The stage production didn’t stray too far from the book version which was a relief, and if the breathtaking story wasn’t enough to tempt you, there are live animals involved which are incredibly cute.

The performance had the audience captivated right up until the end, thanks to the brilliant cast and moving, gripping storyline.

It was a very honest portrayal of a disorder that many people don’t understand and I think the show has done an amazing job in raising awareness of Asperger’s Syndrome.  

This really is a show that shouldn’t be missed – I can honestly say it has now become my favourite theatre production so far.
