Jackaby: William Ritter

This was the first of the Jackaby series. We learn how Abigail Rook was hired on by Jackaby and how she got her first look and case into the supernatural. Someone in town was on a killing spree and Jackaby knew the murderer to be a "red cap" and to be in the police force. He found the monster and terminated him while also finding a canine shape shifter in the mix.
