Sir Arthur Conan Doyle, the preeminent English writer, is known worldwide as an unrivaled master of the detective and adventure genres. However, despite the diversity of his creative legacy, it's easy to see how Doyle was always drawn primarily to mystical, enigmatic, and inexplicable phenomena, which permeate almost all of his works. Few can match his ability to create a disturbing atmosphere of mystery, in which the presence of a magical, unknown force is felt. This collection presents stories in which the mystical side of the writer's work is most vividly expressed: tales of ghosts, diabolical images, soul journeys, and much more, no less surprising and strange.
