Treachery in Death (In Death, Bk. 32)

In this thriller in the #1 New York Times bestselling phenomenon, Eve Dallas tracks down those who break the law--including the ones sworn to uphold it.
 
Detective Eve Dallas and her partner, Peabody, are following up on a senseless crime--an elderly grocery owner killed by three stoned punks for nothing more than kicks and snacks. This is Peabody's first case as primary detective--good thing she learned from the master.

But soon Peabody stumbles upon a trickier situation. After a hard workout, she's all alone in the locker room when the gym door clatters open, and--while hiding inside a shower stall trying not to make a sound--she overhears two fellow officers arguing. It doesn't take long to realize they're both crooked--guilty not just of corruption but of murder. Now Peabody, Eve, and Eve's husband, Roarke, are trying to get the hard evidence they need to bring down the dirty cops--knowing all the while that the two are willing to kill to keep their secret.
