Eleven short stories assembled for American readers open with the courtroom drama that gives the collection its name, in which a barrister takes on the defence of a young man accused of murdering a wealthy widow, only to find the case turning on the testimony of the accused's own wife. The remaining ten tales range widely in tone. Several are crime puzzles built on deception, inheritance, and quietly murderous intent, while others move into the supernatural and the psychic: premonitions, seances, voices warning of danger, and minds that may be unraveling. A woman senses doom through a loaded revolver; a cottage marriage curdles into menace; a fortune drives a household toward violence; and a single Poirot story, the one recurring character here, threads classical detection into the mix. Drawn from earlier British collections that never reached the United States as a set, the stories were gathered to introduce a new audience to Christie's shorter work across her favorite registers. The mood shifts from controlled and clever to genuinely uneasy, with twists arriving in the final lines. Settings stay domestic and contained, country houses, train carriages, and drawing rooms, which sharpens the sense that danger sits close to ordinary life. Read together, the stories show Christie testing the boundaries between rational mystery and the inexplicable, returning again and again to the gap between what characters believe and what is actually true.
