Twelve stories step away from the drawing-room puzzle and into the uncanny, where the dead press at the edges of the living and ordinary people meet forces they cannot reason away. Premonitions arrive uninvited, a wireless set carries voices it should not, a séance asks more of its medium than she can give, and an inheritance arrives wrapped in something older and stranger than money. Detection takes a back seat here; instead the stories turn on fate, suggestion, the wavering line between sanity and delusion, and the question of whether what a character sees is real or a symptom. Several pieces read as outright tales of the supernatural, while others keep one foot in psychological dread, letting the reader wonder whether the haunting is external or internal. Among the twelve sits the original short version of "The Witness for the Prosecution," a courtroom story that would later become a celebrated play and film, and "The Last Séance," widely regarded as one of the bleakest things its author wrote. The tone shifts from quiet unease to genuine horror across the collection, and the brevity of each piece sharpens its sting. Read together, the stories show a familiar mystery writer working in a register of premonition, mediumship, and dread rather than deduction, with twist endings that reward attention without depending on a recurring sleuth.
