Promises in Death — J.D. Robb

Amaryllis Coltraine may have recently transferred to the New York Police and Security Department from Atlanta, but she had been a cop long enough to know how to defend herself. When Coltraine was taken down by an assailant and killed with her own weapon just steps away from her apartment, for Eve the victim wasn't simply "one of us." Dallas's friend Chief Medical Examiner Morris was in a serious relationship with Coltraine, and from all accounts, the two of them were headed toward a happy future together -- until someone put an abrupt end to all of that.

After breaking the news to Morris, Eve starts questioning everyone, including Coltraine's squad, informants, and neighbors, while Eve's husband, Roarke, digs into data on the dead woman's life back in Atlanta. To their shock, they discover a connection between this case and their own painful, shadowy pasts.

The truth will need to be uncovered one layer at a time, starting with the box that arrives at Cop Central addressed to Eve, containing Coltraine's guns, her badge and ID, and a note from her killer.

YOU CAN HAVE THEM BACK. MAYBE SOMEDAY SOON, I'LL BE SENDING YOURS TO SOMEBODY ELSE.

Eve Dallas doesn't take kindly to threats; she is going to break this case, whatever it takes. And that's a promise.
