A Good Girl's Guide to Murder stays "true" to books – after author made a "lot" of changes

"So we worked a lot on bringing that back because I knew that the reason the books are where they are is because of the readers, and if we made a show that they weren't happy with, we're kind of screwing ourselves over there."

The victim's boyfriend confessed to the crime, before taking his own life, but Pip believes the killer is still out there...
