Cupples is the quiet hinge of the affair: it is through his friendship with Trent and his loyalty to his niece that the detective is drawn into the Manderson household at all. He is a man of disquisitions and moral reflections, alert as a bird at breakfast, delighted by the prospect of an inquest, and utterly without guile. His trust in Trent and his anxious care for Mabel give the investigation its human stakes, and his talkative, well-read presence is the calm counterweight to Trent's restless suspicion.
