I FEEL I have to write about the production of The Curious Incident Of The Dog In The Night Time at the Grand Opera House last Thursday.

I had looked forward to this production ever since I’d heard that the London-based play was touring, having seen something of how it was ‘miraculously’ staged via a BBC2 TV programme last September, and having read the book nearly a decade ago.

It was an amazing, uplifting and moving rendition of a unique book: it gave a real insight into Aspergers. It gripped the audience, many of whom were young people from (I’d hazard a guess) various sixth forms.

I found their roars of approval at the end almost as moving as the play, and a real accolade to the amazing physical and emotional performances that were in themselves acts of faith truly well invested.

Heartfelt thanks to the actors (Joshua Jenkins in particular, a 27-year-old giving us a convincing 15-year-old, who had a middle-aged streak just to make it even harder; there are two ‘Christophers’ as it would be impossible to do a year-long tour with one person playing the key role), the production team and stage crew; and above all to Simon Stephens and Mark Haddon for their mutual belief and risk-taking.

Oh yes and I understood Pythagoras for the first time.
