It was done ; he had won . The trip back should take only a couple of minutes . Replacing the wire cutters in his kit , he held the pencil flash before him and started retracing his route . He passed the twelve o'clock brace , pinned it in place again and saw one of his tools floating to the right of his head . He gathered it in and swept his tiny flash around in search of other jetsam from his tool kit . He collected a wrench and the skittish flashlight , started toward the last brace between him and the ladder , and felt his legs go limp . He was n't particularly alarmed about it ; his arms and vision failed him too , but his brain had n't enough incoming oxygen to care much , one way or the other .
