Silent, but Deadly

You grab a rope from your backpack and toss the claw end up to the roof of the tower. The rope catches on the edge and you start to ascend upwards. Halfway up the forty-foot tower, the alarm blares. The alarm awakens the entire base camp
It seems that you forgot to take into consideration that the possibility of a sentry would be posted on the roof of the tower. The sentry peers over the edge and flashed his spotlight directly at you. You cannot see form the bright, intense light. You are blinded to the point that you do not realize a round has left the chamber of his rifle and penetrated your skull.
