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."
Sir Arthur Ignatius Conan Doyle KStJ DL (22 May 1859 – 7 July 1930) was a British writer and physician. He created the character Sherlock Holmes in 1887 for A Study in Scarlet, the first of four novels and fifty-six short stories about Holmes and Dr. Watson. The Sherlock Holmes stories are milestones in the field of crime fiction.
