Gated Prey by Lee Goldberg
Gated Prey is a popcorn book for me. It's the kind of book that seems like a mystery/action movie or tv show. I mean that as a good thing. It's action-packed and the setting and characters are described well.
Eve and Duncan are on an undercover sting operation, trying to catch some home invaders. The sting goes wrong and all three of the perpetrators end up dead. While still investigating the robberies and whether there was an accomplice, they get called to what should be a routine stillbirth in another of the gated communities, but it turns out to be much more complicated. For once, the two mysteries are not actually connected. Gated Prey is the third in the series and I would recommend reading them in order. Eve's background and previous cases definitely affect what's going on here and even though they're mentioned, you'll have a better idea of what's going on in the background if you've read the others...
