Think Like the Killer

Harmon Bliss thinks he's a psychopath.
Harmon has an odd obsession with death, especially when it revolves
around murder. He knows about many popular crimes but when a local
girl introduces him to a eight-year-old cold case it's the only thing he can
think about. Who killed Julia Manhattan and why?
Suddenly, this case is taking over his life and he thinks he may actually be
able to solve this unsolved murder and the case of his missing classmate
in the process. Can he do it?
