In "The Last Unicorn" by Peter S. Beagle, the narrative takes a turn when the characters hear an unexpected sound that lingers beyond the usual noises of the night. This sound, peculiar and haunting, is described as the tiny, dry sound of a spider weeping. It evokes a sense of sorrow and frailty, suggesting a deep emotional resonance in an otherwise fantastical tale.

This imagery serves to highlight the poignant themes of loss and longing that permeate the story. As the characters navigate their strange journey, the presence of the weeping spider symbolizes the underlying sadness that can accompany beauty and wonder, reminding readers that even in enchanting worlds, sorrow can echo through, quietly yet profoundly affecting all who hear it.
