He is a vampire

WARNING: Twilight reference

You took a deep breath, gathering all your courage into a fist. The words you had rehearsed in your head came out in a choked whisper:

"I know who you are..."

One step, two, and he was standing right in front of you, so close that you could feel the coolness coming from him. He leaned slightly forward, reducing the distance to a minimum. Now his eyes were right in front of yours.

"Say it... Out loud," he said softly. There was no threat in his voice, but rather a kind of lingering expectation. It was as if he was giving me the last chance to retreat, write everything off as fantasy, or take a step to the point of no return.
