Monster Quassim Winters Per.1

My book is called Monster by Jonathan Kellerman. Its a pretty good book so far. Currently, the detcetives are interrogating other suspects in the murder case. So far, they have found nothing or any information needed for the case. Not even from the victim's family. As the search for the killer goes on, it gets more difficult for the agents. With no lead or clue, it'll be a miracle if they manage to catch he or she.
