"Five seconds, at most"

	If I killed the girl first, I would have only fifteen or twenty seconds with her before the humans in the room reacted. Maybe a little longer if at first they did not realize what I was doing. She would not have time to scream or feel pain; I would not kill her cruelly. That much I could give this stranger with her horribly desirable blood.
	But then I would have to stop them from escaping. I wouldn't have to worry about the windows, too high up and small to provide an escape for anyone. Just the door- block that and they were trapped.
	It would be slower and more difficult, trying to take them all down when they were panicked and scrambling, moving in chaos. Not impossible, but there would be much more noise. Time for lots of screaming. Someone would hear...and i'd be forced to kill even more innocents in this black hour.
	And her blood would cool while I murdered the others.
	The scent punished me, closing my throat with dry aching....
	So the witnesses first, then.
	I mapped it out in my head. I was in the middle of the room, the row farthest from the front. I would take my right side first. I could snap four or five of their necks per second, I estimated. It would not be noisy. The right side would be lucky; they would not see me coming. Moving around the front and back down the left side, it would take me, at most, five seconds to end every life in this room.
