Who Killed Frank?

What would you do if someone murdered your best friend and mentor?

Private investigator Harry Starke owes his career to Frank Callahan, the tough-as-nails detective who trained him as a young cop. But when Frank is found brutally murdered in his own home, Harry can't let it go. 

The crime scene reveals a chilling connection: photos from the unsolved Riverside Strangler case-ten women killed along the Tennessee River a decade ago. Frank had spent his retirement obsessed with the case, convinced something vital had been overlooked. His final note left Harry reeling: "Catherine Wells is still alive." Wells was supposed to be the fourth victim.

As Harry follows the trail, he uncovers a conspiracy buried deep in the city's power structure-corruption so dangerous that people are willing to kill again to keep it hidden. Now, someone is watching Harry's every move… and they'll do whatever it takes to silence him.

Harry must decide: walk away, or risk his own life to expose the truth.

Perfect for fans of Michael Connelly, Lisa Gardner, and Robert Dugoni.
