Two can keep a secret . . . but only if one dies!

With NYPD's finest on the hunt to find who killed one of their own, the newly-promoted Jessie Kensington won't stop until she finds her best friend's killer, even pushing her wedding plans aside.  

Convalescing after being shot during a hostage situation, Jessie's partner, Zach Gerard, is doing whatever he can to help her solve this crime because he knows she won't focus on their wedding if he doesn't.

When the case appears to be at a dead-end, Jessie remembers Maureen's compulsion for detail and the nagging feeling that tells her she's missed something. A late-night visit to the crime scene reveals a carefully constructed, chess-like sequence of clues left behind in the dangerous game Maureen played that is so devastating it will leave her community of brothers and sisters reeling.

Now, the focus is on discovering where those clues lead, even if it means putting her own life at risk!
