A Magician Among the Spirits by Harry Houdini examines the world of spiritualism, mediumship, séances, and alleged communication with the dead. Drawing on his experiences as a celebrated magician and escape artist, Houdini investigates claims of supernatural phenomena and describes the methods he believed were used to create convincing spiritualistic effects.

Houdini approaches the subject from the perspective of an experienced illusionist, explaining how deception, stagecraft, suggestion, and carefully constructed performances could produce seemingly mysterious results. His investigations also reflect his broader interest in distinguishing genuine phenomena from fraudulent practices.

Combining investigative writing, personal experiences, and descriptions of spiritualistic performances, A Magician Among the Spirits provides a fascinating historical perspective on the early twentieth-century debate surrounding spiritualism, mediumship, magic, and the supernatural.
