Art Auctions - How do auctioneers and buyers transact sales in seconds? Laurie Taylor hears from Professor Christian Heath who discusses his detailed study into the tools and techniques which lead to the strike of a hammer. They're joined by the arts writer and critic, Georgina Adam. Also, the Guatemalan cemetery with no more room. The growth of the city combined with high death and murder rates means the cemetery is overflowing. The anthropologist, Kevin O'Neill, talks about the harsh effects of an aggressive policy of disinterment when poor relatives can't pay the dues.
