The Jewelled Arrow by S.M. Mitra

So the king summoned his guards and ordered them to take his wife to a strong prison and leave her there. She went with them without making any resistance, only turning once to look lovingly at her husband as she was led away. Vira-Bhuja returned to his own palace and had not been there very long when he got a message from Ayasolekha, begging him to give her an interview, for she had something of very great importance to tell him. The king consented at once, thinking to himself, "perhaps she has found out that what she told me about my dear Guna-Vara is not true."

Great then was his disappointment when the wicked woman told him she had discovered a plot against his life. The son of Guna-Vara and some of the chief men of the kingdom, she said, had agreed together to kill him, so that Sringa-Bhuja might reign in his stead. She and some of the other wives had overheard conversations between them, and were terrified lest their beloved Lord should be hurt. The young prince, she declared, had had some trouble in persuading the nobles to help him, but he had succeeded at last.
