Dr Michael Parker Pearson is a lecturer in the Department of Archaeology at the University of Sheffield, which specialises in this field. He has also written 'The Red Slave' for Sutton Publishing.
This is the standard text for mortuary archaeology. Parker-Pearson has now moved to UCL and has become ever more prominent in the field. I suppose that this could do with some updating with spectacular recent finds but it still the best book of its kind currently available.
another excellant book by M.P.P. well written, good slant on probability and possibility. with good evidence...(Whats next Neolithic cannibalism, or may be the use of drugs in the stone age .
