Now that we've covered the story essentials of the strange case of Mary Lurancy Vennum, known as "The Watseka Wonder," it's time to take a look at the possible causes and mechanics of this apparent miracle. Suppose Lurancy's possession was merely the imaginative prank of an attention-seeking impressionable teenager. How then did she know intimate, inscrutable details of her possessor Mary Roff and that of her family, when Mary had died over ten years before she was born and the Roff family were vague acquaintances? It's perhaps possible that this naive fourteen-year-old had mastered the manipulation techniques employed by experienced Mentalists and charlatan psychic mediums to fool desperate parents, but how likely is that? In Part Two of our series, we consider the investigation of a noted psychical researcher at the time, Dr. Richard Hodgson, who interviewed witnesses and studied case notes about thirteen years after the significant events in light of contemporary hypotheses.
