To Catch a Killer is a quick, fun read.

Erin's mother was killed fourteen years ago and the killer was never brought to justice. He's still out there somewhere. Her small town simply didn't have the resources to work such a complex case and large amounts of evidence still sit in a box in the police precinct. Well, that is until Erin snuck the box out of the precinct and up to her secret attic space at Rachel's house. Rachel was her mother's best friend and has been Erin's guardian for nearly all her life now.

Curious to work the case and to possibly find out who her mystery father might be, Erin partners with her biology teacher to process DNA. Unfortunately, the biology teacher is killed before she can do any of this work and it's Erin who discovers the body.

Now she's a "person of interest" in this recent murder case. But Erin knows she didn't commit the murder. She thinks the person who killed her teacher might also be the one who killed her mother and now, Erin's caught in a deadly game of cat and mouse as she tries to nab the killer before she and her friends are next.

I enjoyed this book, for the most part. Sure, the teenagers were smarter than everyone else around them and instalove is definitely at play, but for the most part, this was an enjoyable read. I greatly enjoyed Uncle Victor and how his novels drive and inform Erin's work.
