This second clue was so out of context, and it really amuses me to have gone off on such a tangent - but what we were looking for was simply a saucer. And this is a rather spectacular saucer, though if you were sat drinking your afternoon tea you might be rather disturbed to see this view outside the window.
I have to admit that when I think of afternoon tea, or any tea it usually does not involve a saucer - but that is because in the curious and hazardous world of the dyspraxic it is just another thing to try to hold on to but end up dropping on the way to the table.
This set has become a cult classic, and, strangely, been the inspiration for a motion picture, rather than the usual practise where a successful film or tv series has cards produced off it. It feeds off the 1960s craze on alien invasion, which reflected the worries about war, threatened war, and nuclear weapons, but as usual is taken to a very gory conclusion, rather than our thinking the alien may be coming down to help us, and welcoming them with open arms.
