I need to get this off of my chest before I even attempt a proper review: Rebecca is the best character, if only for this: (view spoiler)["[J]ust didn't realize you had time for this in between a police investigation and your missing roommate." This is in regards to arriving at Leah's place to find Kyle sneaking out the backdoor. (hide spoiler)] Talk about speaking for the reader. Thank you for that, Rebecca. 
 There are few tropes that have kept me from finishing otherwise good books and even better series, but the (view spoiler)["LEO sleeps with victim/witness/suspect" trope (hide spoiler)] is at the top of that list. I literally groaned aloud when it happened in this otherwise good story about two incredibly interesting women. To make it quite worse in the case of The Perfect Stranger, there's some acknowledgement of the ridiculousness but then it happens all over again! Look at me and my exclamation points--this idiocy has me using exclamation points, and I apologize for the extra. 
 Overall, a story that kept me turning pages and the overall themes of identity subjective truths are always goodies, especially in the hands of a writer willing to make her characters a little bad, very flawed, and multi-dimensional. The last quarter made up for the missteps in the first half hence the four stars.
