Ok! I think I know who the murderator is. That's the only thing we
have to send in to qualify huh?
Explanations are not necessary (I think) , but last time there were prizes for amusing explanations. (hey!

I won one, but lost it when my hard drive crashed

- that reminds me I should chase that up.)
My notes now run to several pages and would make your head spin, so maybe I should not send them in. I still have a couple of hours to work this out properly.
