In the StoryEdit
In Storm Front, Gimpy stole Harry's hair. Harry was pretty sure he was going to give it to the sorcerer casting the spells that blasts the heart of people, like: Jennifer Stanton. And, that he's next. Harry becomes desperate to find Gimpy and get his hair back. He uses a Thaumaturgy tracking spell that locates Gimpy at the Varsity where Marcone and Hendricks are.  Harry reveals Gimpy's dual loyalty to Marcone, refusing to show his wrist where Harry scratched him, and during the resulting fight, he is shot dead by Hendricks.
