Boxed

In this horrifying zombie short story, seven characters find themselves trapped inside an elevator during a zombie apocalypse. The narrator, the last passenger to occupy the elevator, tells them that his wife, who was murdered by a zombie, told him as she died in his arms that she saw one of the passengers get bitten by a zombie before the person ducked into the elevator, but she died before she could describe the victim to him. The terrified passengers know that the victim will soon turn and attack them. They must determine who it is and kill him or her before it is too late--if they don't kill each other first trying to find out.
