"L'hôte inconnu" by Maurice Maeterlinck is a nonfiction treatise on psychical research written in the early 20th century. It examines apparitions, haunted houses, telepathy, clairvoyance, and psychometry, balancing spiritist claims against psychological and empirical interpretations grounded in contemporary casework. Expect a cautious, case-driven inquiry that favors sober analysis over sensationalism.

The opening of the treatise frames the project with a wartime preface that dismisses popular occultism’s theatrics while affirming that carefully observed psychic phenomena persist, then lays out a two-part plan: first apparitions, hauntings, premonitions, and psychometry (plus the Elberfeld horses); later, Lourdes miracles, materializations, and dowsing. Establishing scope, it leans on the Society for Psychical Research to move from legend to controlled facts, lists the main phenomena, and warns about fraud even as it cites tightly run séances (such as Bottazzi’s work with Paladino). It then surveys phantasms of the living and the dead and “haunted houses,” stressing their quiet, domestic character and weighing spirit-survival against telepathic or memory-based explanations through cases that remain suggestive but not conclusive. Next it defines psychometry—using a handled object to access distant or hidden information—illustrating it with experiments (notably with a medium dubbed Mme M) and a striking missing-person case traced via a scarf, which seems to force either postmortem communication or an object acting as a link in a vast web of forces. The section concludes by favoring this latter, non-spiritist reading, noting cross-correspondences and urging strict controls while attributing the key faculty to gifted mediums rather than to general latent intuition.
