This is the story of a girl who is mistaken for a werewolf. A professor is called in to solve the mystery of the werewolf that appears every year at this time. A werewolf is a vampire, a dead human being that leaves its grave at night and takes any form it chooses, usually that of a wolf. Anybody whose throat is slashed and blood drunk by a werewolf will die and turn in to another vampire. 

The story  appeared in The American Weekly under the title, "Lived Like A Little Wild Beast For Seven Years."
