Werewolves are everywhere, but which one is a killer?

There are five days each month when those cursed with lycanthropy are forced to change. The police called me early on day five. Four women dead, one killed each night. And the brutality of the four attacks implies the killer is a new werewolf, better known as a Wild Pooch. That gave me and my lady less than eighteen hours to find the killer werewolf and save a life.

Thing is, someone in power is blocking the investigation, and there are a lot of werewolves in town.
