Crime and the Crystal ( 1909 )

I leave it to the reader to decide how much of what follows is credible. Today, we take it for granted that images seen in the crystal - whatever their validity - are purely subjective, and cannot be shared by a third party. This Victorian account begs to differ. Otto Von Bourg, the crystal gazer mentioned in the text, did indeed garner worldwide headlines after his apparent discovery of the body of Mr Foxwell.  The Merstham tunnel murder was never solved .

It is only fair to warn the reader that one of the witnesses to the phenomena mentioned here - Miss
Ada Goodrich Freer - has been posthumously accused of plagiarism and fraud, though not  in connection with any of the 'crystal' cases.
