The book describes a tragic story involving a young maiden of 'the rarest beauty'. She loved and wedded an eccentric painter who cared more about his work than anything else in the world, including his wife. The painter eventually asked his wife to sit for him, and she obediently consented, sitting "meekly for many weeks" in his turret chamber. The painter worked so diligently at his task that he did not recognize his wife's fading health, as she, being a loving wife, continually 'smiled on and still on, uncomplainingly'. As the painter neared the end of his work, he let no one enter the turret chamber and rarely took his eyes off the canvas, even to watch his wife. After 'many weeks had passed', he finally finished his work.
