McTeague: A Story of San Francisco by Frank Norris:
There was no passion in the dentist's regard for his wife. He dearly liked to have her near him, he took an enormous pleasure in watching her as she moved about their rooms, very much at home, gay and singing from morning till night; and it was his great delight to call her into the "Dental Parlors" when a patient was in the chair and, while he held the plugger, to have her rap in the gold fillings with the little box-wood mallet as he had taught her. But that tempest of passion, that overpowering desire that had suddenly taken possession of him that day when he had given her ether, again when he had caught her in his arms in the B Street station, and again and again during the early days of their married life, rarely stirred him now. On the other hand, he was never assailed with doubts as to the wisdom of his marriage.
