If illness became him, it was only because he was fond of ritual, the children thought — even the hideous ceremonial of pain. But Irina had not been intended for sickness and suffering; she was meant to be burned dry and consumed by the ritual of him. The children believed that the end of his life would surely be the death of their mother. They did not really expect Irina to turn her face to the wall and die, but an exclusive, even a selfish, alliance with Notte had seemed her reason for being. As their father grew old, then truly old, then old in mind, and querulous, and unjust, they observed the patient tenderness with which she heeded his sulks and caprices, his almost insane commands. They supposed this ardent submission of hers had to do with love, but it was not a sort of love they had ever experienced or tried to provoke. One of his sons saw Notte crying because Irina had buttered toast for him when he wanted it dry. She stroked the old man's silky hair, smiling. The son hated this. Irina was diminishing a strong, proud man, making a senile child of him, just as Notte was enslaving and debasing her. At the same time the son felt a secret between the two, a mystery. He wondered then, but at no other time, if the secret might not be Irina's invention and property.
