Hair of the Dog

S1 E3: Murphy brings Dresden to a Chicago park, where the latest in a series of bizarre killings has taken place. A young woman is dead, her hair shorn and her canine teeth pulled out. Further investigation reveals that the victim was a werewolf, and that she was killed by a lethal dose of silver iodide administered via an aerosol inhalant. It appears that the werewolf chased someone into the park, but the wolf's intended victim turned the tables and killed her with the silver iodide, then harvested the wolf's hair and teeth. But why? Meanwhile, Murphy finds herself forced off the case by an aggressive FBI agent who has been tracking the serial killer across the United States. But Dresden realizes that this is merely the agent's cover story - she's not tracking the killer, she's the mastermind behind this monstrous plot.
