The Devil's Smile

"You have the devil's smile." That's what she told me; before we kissed unseen under the bloated moon. I remember the air was chill. Wisps of our breath escaped into the air as we parted our kiss. "That was a devil's kiss." She teased, with an expression so coy.
"What is it?" She exclaimed, a hint of panic trembled in her voice. She had seen the glint of steel in the moon's cold light. "You have the devil's eyes!" She cursed as I plunged the knife deep.
"I have the devil's smile." I whispered alone and slipped into the night.
