It's a real triumph, the original book relies on the internal monologue of the protagonist Christopher Boone. He describes himself as a 'mathematician with behavioural difficulties' in the book. His owns descriptions of his personality, his adventures and problems means instant if slightly disturbing identification with the reader. That kind of instant link is quite difficult to transpose to a play format. But the national does it brilliantly, much of the book is read out word for word. Christopher's teacher, the one non-dysfunctional character in the tale also becomes part narrator.
The set is made up of a set of squares on the floor which light up and move. Objects are created by actors moving and mimicking gestures. There is virtually no furniture, only costume and the trains Christopher plays with constantly. Most of the actors also play different parts which works surprisingly well as it helps the audience to feel Christopher's own disorientation when he has to face the real world.
The stories centres around the killing of the neighbour's dog which Christopher finds speared with a gardening folk. He is initially blamed for the 'incident' but as he 'liked' that and knows he didn't do it sets out to find the killer.
This is a great show to watch, staged in the tiny Cottsloe theatre, the audience is taken into the weird and wonderful of Christopher's brain and gets a sense of how at least to him the world doesn't quite make sense.
