Thank you all for trying to help. I appreciate that. Most of the questions are mine Boxtops, because despite help from a few ABers I still haven't found a sweet of 1 word of 12 letters that fits the criteria for the story, ie they look like UFOs, and at the same time are deadly and terrorised travellers. As with anything space themed, the setters imagination has got us all guessing this time, and I hate to be beaten, but I do like to support the Macmillan cause.
