You looked at Francis, he looked normal, his ID was fine, there was nothing suspicious about him, so you let him in, you waited when you can go home thinking you did well, but...

Black hands gripped you by the throat, one was over your mouth to keep you from screaming as there appeared to be Francis, thought his eyes were wide open with a grin full of sharp teeth, as he says.

GAME OVER, you are mine NOW!

His eyes go wider when he says the last word, as so does his grin.
