Elsewhere in the text: "After they had taken her body away, he had noticed her cup of coffee, still hot, on the table in front of the couch she'd died on—and he had numbly realized that he would not be able to bear it if the coffee were eventually to cool off, if it were to wind up as passively tepid as some careless guest's forgotten half can of soda pop. He had carefully carried the cup down the hall to the kitchen and put it in the stove and turned the broiler on low. And he had told the concerned neighbors that Susan had fainted, and later in the day he had explained that she was back, but resting." So, the answer to your question is "yes".
