Fred the Head: And Other Unsolved Crimes

 In March 1971 an off-duty special police constable found the macabre remains of a body...  The skull, protruding from the ground, revealed the skeleton of a man who had been violently murdered and buried in a shallow grave by the river Trent in Staffordshire. The naked body, except for a pair of pink socks and a wedding ring, yielded little evidence and to this day has resisted all police efforts and appeals to the public to identify him. It remains an unsolved murder of an unknown man who, for want of a better name, is called Fred the Head.
