The River Thames looked lovely on this warm, sunny afternoon, Emma Morley thought. It was a work day, but Emma wasn't at school. Teaching had finished for the term but there was a very important staff meeting happening at the school. Emma was needed there, but she didn't really care about that. She had phoned the headteacher's secretary that morning and told her that she was ill and had to stay in bed. The woman clearly hadn't believed her. Emma didn't care about that either.
