Museum (II)

Mark's eyes shrunk, seeing the zombie clutching his feet. The zombie was going for his feet with its mouth wide open. He immediately took out his gun and shot it in its head, killing it. He looked back and saw the rest of them are very near and shot at the elbow. 

The body detached itself from the elbow and he pulled himself up. Jumping over the wall, he immediately kneeled down, catching his breath. He looked at his leg and could hear his heart beating. David's face was full of shock when he saw the zombie hand attached to his leg. 

He slowly reached out for the hand and pried it open. He threw away the hand and closely examined the ankle. He had a bruise because of its tight grip, but his skin was not cut. He exhaled in relief and slowly stood up. It relieved David when he saw nothing happened. 

"Mark, what just happened in there? Didn't we see the zombies making their way towards the parking lot? How were they back so quick?"
