The spiritual movement in the early twentieth century had few, if any, proponents greater than Sir Arthur Conan Doyle—a medical doctor, soldier, and world-renowned author. This book is a firsthand account of his investigation into the world of spiritualism.
An original Introduction to the book provides an insightful look at Doyle's personal life. His friendship with magician Harry Houdini is brilliantly captured in the book's original Afterword.
