What a fabulous book; superbly written and very entertaining. We have a child with Semantic Pragmatic Disorder (on the autism continuum aEUR" but less severe than AspergeraEUR(tm)s) in the family and I recognized lots of traits. I felt so sorry for ChristopheraEUR(tm)s dad in places. I thought that the policemen were portrayed as somewhat clueless though and I would expect them to be more aware of this condition in reality
