Blood Money — James C. Paavola

Two bodies are discovered within a mile of one another, one a teenage prostitute, the other an investment counselor. Memphis Police Lieutenant Julia Todd and her team's investigations take them in two directions: Mexican cartels and Ponzi schemes. The two inquiries eventually intersect at a common theme -- the multi-billion dollar business of money laundering. A Mexican cartel orders hitmen to track down targeted Americans. Julia's name is on that hit list. This is Paavola's fourth book in the Murder In Memphis series.
