Domnei by James Branch Cabell

Dame Melicent walked proudly through the Women's Garden, and presently entered a grove of orange trees, the most of which were at this season about their flowering. In this place was an artificial pool by which the trees were nourished. On its embankment sprawled the body of young Diophantus, a child of some ten years of age, Demetrios' son by Tryphera. Orestes had strangled Diophantus in order that there might be no rival to Orestes' claims. The lad lay on his back, and his left arm hung elbow-deep in the water, which swayed it gently.

Callistion sat beside the corpse and stroked its limp right hand. She had hated the boy throughout his brief and merry life. She thought now of his likeness to Demetrios.
