my mum is looking for a book and it's driving her mad. she has read it before but can't remember what it's called or who wrote it. she's tried all kinds of Google searches but can't find it. she said it starts with a helicopter search for a small boy who is up a tree but he is initially missed because of the way the light is shining. A main part of the book is that a man hates women so he urinates around the house, I think it's a murdery kind of book. does this sound familiar to anyone?
