Not Above Suspicion — Joe Krogman

What do a wily county sheriff, a hard-driving Kansas City homicide detective, and a former NIS agent turned PI have in common? Frustration over two unresolved cases: murders with insufficient evidence to prosecute the leading suspects. John Harwell is determined to solve one cold case with the sketchy evidence from another cold case. But he has a major problem. The leading suspect in the murder of a state senator's wife is dead: his charred body recovered from an incinerated car with a bullet hole in the back of his head.
