Sách nói: Master of Mysteries

"It so happened that the circumstances of fate allowed me to follow my own bent in the choice of a profession. From my earliest youth the weird, the mysterious had an irresistible fascination for me. Having private means, I resolved to follow my unique inclinations, and I am now well known to all my friends as a professional exposer of ghosts, and one who can clear away the mysteries of most haunted houses....I propose in these pages to relate the histories of certain queer events, enveloped at first in mystery, and apparently dark with portent, but, nevertheless, when grappled with in the true spirit of science, capable of explanation." - from the Introduction to "A Master of Mysteries"
