While the six detectives are chasing Sunday through the streets of London, he keeps throwing notes back to his pursuers, notes such as "Fly at once; the truth about you trouser stretchers is known" or "What about Martin Tupper now?".
So, why did he throw these notes? Did any of them have the slightest bit of rhyme or reason in them? If so what did they mean?
Any thoughts, additions, theories, answers ... next discussion questions? If so please do comment with them.
