Fall (Detective Harriet Foster, #2) by Tracy Clark

In the second book in the Detective Harriet Foster thriller series, author Tracy Clark weaves a twisted journey into the underbelly of Chicago as Harriet and her team work to unmask a serial killer stalking the city’s aldermen.

The Chicago PD is on high alert when two city aldermen are found dead: one by apparent suicide, one brutally stabbed in his office, and both with thirty dimes left on their bodies—a betrayer’s payment. With no other clues, the question is, Who else has a debt to pay?

Detective Harriet Foster is on the case before the killer can strike again. But even with the help of her partner, Detective Vera Li, and the rest of their team, Harriet has little to go on and a lot at risk. There’s no telling who the killer’s next target is or how many will come next.

To stop another murder, Harriet and her officers will have to examine what the victims had going on behind the scenes to determine who could be tangled up in this web of betrayal…and who could be out for revenge.
