Countess Grace’s new butler, Ovateron, is bewildered on his first day on the job. The Countess’s young lady, Emma, is a very different person from the one the world knows. Pitying Emma, who is ignored by her family and maids because of her disfigurement, Oberteron dutifully serves her, resisting all temptation, until one day she catches his eye and makes a bold proposal.
“Will you do anything for me that isn’t for Grace?”
