Dorian walked to the door with a look of pain in his face. As he drew the curtain aside, a hideous laugh broke from the painted lips of the woman who had taken his money. "There goes the devil’s bargain!" she hiccoughed, in a hoarse voice.
"Curse you!" he answered, "don’t call me that."
She snapped her fingers. "Prince Charming is what you like to be called, ain’t it?" she yelled after him.

– Oscar Wilde

The Picture of Dorian Gray, Chapter 16. When Dorian enters a squalid opium den, his face full of pain and haunted by the memory of Basil Hallward, a woman jeers him. She mockingly refers to him as "the devil’s bargain" and what he once liked to be called – "Prince Charming." She sums up perfectly how Dorian has progressed from being Sibyl’s innocent Prince to what he is now – a corrupt disciple of the devil who made a Faustian bargain to trade his soul for eternal youth and beauty.
