This was one of those carefully planned jobs, as in a 60's film, down through the roof, while no-one in the streets looked up, so probably done to order.

I heard a tale once of the sort of person behind these things concerning a rare fossil, of which there were only two perfect examples. One fell into the hands of a rich collector, who then spent time and effort to purchase, eventually, the second one, thus removing it from the realms of academia, where it could be studied. He then (I am assuming, on internal evidence alone, he) smashed one of them, so he could say that he had the only one in the world. So I was told.

Emotional age of three?
