"So consider this a friendly warning, my dear." Moriarty purrs. "Back off." The words have a dangerous undertone, and his voice comes out in a growl.
Sherlock studies the criminal in front of him. He's shorter, dark brown hair, sharklike smile. Definitely even close to the timid gay man that he'd met earlier.
"Or what? You'll kill me, I suppose." Please, don't be dull. That would be such a disappointment. Such a... almost a betrayal.
"No. Don't be obvious. I mean, I'm obviously going to kill you anyway. No. If you don't stop prying... I'll burn you. I will burn the heart out of you."
He can do his worst. Sherlock is ready for him.
