#3 the curious incident of the dog in the night-time

In the part of the book after Christopher learns that his mother is alive and his father killed Wellington, he makes the decision to go and live with his mother in London. Although he is scared of his father, I would strongly disagree with the decision to run away. This trip is very dangerous for someone  in Christopher's age and state to be making alone. Christopher's dad could have handled the situation a little better and not have left him alone at home.
