Arthur Conan Doyle 
Case for Spirit Photography 

Excerpt: "The publicity given to the recent attacks on Psychic Photography has been out of all proportion to their scientific value as evidence. When Sir Arthur Conan Doyle returned to Great Britain, after his successful tour in America, the controversy was in full swing. With characteristic promptitude he immediately decided to meet these negative attacks by a positive counter-attack, and this volume is the outcome of that decision."
