i whisper frantically , trying to find her in the screens , trying desperately to see if any of the probes are watching her ride thru the city- but i do n't see nothing- do n't see nothing but the huge wall of water come shooting out over the hilltop , pushing a town-sized cloud of fog and steam before it- `` viola , '' i whisper again- `` here she is , '' the mayor 's voice says- and he switches to a probe view that 's her and bradley on their horses , racing for their lives up the road thru town- and there are people running , too , but there ai n't no way under heaven they 're gon na outrun the water smashing into the bottom of the falls and flinging its way forward , thru clouds of steam and fog- a wave heading right for the city- `` faster , viola , '' i whisper , pressing my face close to the screen .
