Peril in the Park, the third in the Jamie Quinn series has Jamie's boyfriend Kip, the director of the city parks, trying to figure out who is behind a recent vandalism spree and under pressure from the city council (and a developer) to okay a new skyscraper to be built on wetlands. After being threatened by email and the murder of a PI connected to the threats, Kip goes missing. Jamie rushes to solve the mystery before Kip is the next to die.
This book had a great plot; there were several aspects to it: the vandalism, the murder of the PI and Kip's trouble at work spilling over into Jamie getting email threats. While it was pretty obvious they were all related (and, I figured out whodunit pretty easily) it was still a gripping read and hard to put down.
